Acceptability judgments are reports of a speaker’s or signer’s subjective sense of the well-formedness, nativeness, or naturalness of (novel) linguistic forms. Their value comes in providing data about the nature of the human capacity to generalize beyond linguistic forms previously encountered in language comprehension. For this reason, acceptability judgments are often also called grammaticality judgments (particularly in syntax), although unlike the theory-dependent notion of grammaticality, acceptability is accessible to consciousness. While acceptability judgments have been used to test grammatical claims since ancient times, they became particularly prominent with the birth of generative syntax. Today they are also widely used in other linguistic schools (e.g., cognitive linguistics) and other linguistic domains (pragmatics, semantics, morphology, and phonology), and have been applied in a typologically diverse range of languages. As psychological responses to linguistic stimuli, acceptability judgments are experimental data. Their value thus depends on the validity of the experimental procedures, which, in their traditional version (where theoreticians elicit judgments from themselves or a few colleagues), have been criticized as overly informal and biased. Traditional responses to such criticisms have been supplemented in recent years by laboratory experiments that use formal psycholinguistic methods to collect and quantify judgments from nonlinguists under controlled conditions. Such formal experiments have played an increasingly influential role in theoretical linguistics, being used to justify subtle judgment claims or new grammatical models that incorporate gradience or lexical influences. They have also been used to probe the cognitive processes giving rise to the sense of acceptability itself, the central finding being that acceptability reflects processing ease. Exploring what this finding means will require not only further empirical work on the acceptability judgment process, but also theoretical work on the nature of grammar.
Japanese is a language where the grammatical status of arguments and adjuncts is marked exclusively by postnominal case markers, and various argument realization patterns can be assessed by their case marking. Since Japanese is categorized as a language of the nominative-accusative type typologically, the unmarked case-marking frame obtained for transitive predicates of the non-stative (or eventive) type is ‘nominative-accusative’. Nevertheless, transitive predicates falling into the stative class often have other case-marking alignments, such as ‘nominative-nominative’ and ‘dative-nominative’. Consequently, Japanese provides much more varying argument realization patterns than those expected from its typological character as a nominative-accusative language.
In point of fact, argument marking can actually be much more elastic and variable, the variations being motivated by several linguistic factors. Arguments often have the option of receiving either syntactic or semantic case, with no difference in the logical or cognitive meaning (as in plural agent and source agent alternations) or depending on the meanings their predicate carry (as in locative alternation). The type of case marking that is not normally available in main clauses can sometimes be obtained in embedded contexts (i.e., in exceptional case marking and small-clause constructions). In complex predicates, including causative and indirect passive predicates, arguments are case-marked differently from their base clauses by virtue of suffixation, and their case patterns follow the mono-clausal case array, despite the fact that they have multi-clausal structures.
Various case marking options are also made available for arguments by grammatical operations. Some processes instantiate a change on the grammatical relations and case marking of arguments with no affixation or embedding. Japanese has the grammatical process of subjectivization, creating extra (non-thematic) major subjects, many of which are identified as instances of ‘possessor raising’ (or argument ascension). There is another type of grammatical process, which reduces the number of arguments by virtue of incorporating a noun into the predicate, as found in the light verb constructions with suru ‘do’ and the complex adjective constructions formed on the negative adjective nai ‘non-existent.’

Words are sensitive to syntactic context. Argument realization is the study of the relation between argument-taking words, the syntactic contexts they appear in and the interpretive properties that constrain the relation between them.
Blocking can be defined as the non-occurrence of some linguistic form, whose existence could be expected on general grounds, due to the existence of a rival form. *Oxes, for example, is blocked by oxen, *stealer by thief. Although blocking is closely associated with morphology, in reality the competing “forms” can not only be morphemes or words, but can also be syntactic units. In German, for example, the compound Rotwein ‘red wine’ blocks the phrasal unit *roter Wein (in the relevant sense), just as the phrasal unit rote Rübe ‘beetroot; lit. red beet’ blocks the compound *Rotrübe. In these examples, one crucial factor determining blocking is synonymy; speakers apparently have a deep-rooted presumption against synonyms. Whether homonymy can also lead to a similar avoidance strategy, is still controversial. But even if homonymy blocking exists, it certainly is much less systematic than synonymy blocking.
In all the examples mentioned above, it is a word stored in the mental lexicon that blocks a rival formation. However, besides such cases of lexical blocking, one can observe blocking among productive patterns. Dutch has three suffixes for deriving agent nouns from verbal bases, -er, -der, and -aar. Of these three suffixes, the first one is the default choice, while -der and -aar are chosen in very specific phonological environments: as Geert Booij describes in The Morphology of Dutch (2002), “the suffix -aar occurs after stems ending in a coronal sonorant consonant preceded by schwa, and -der occurs after stems ending in /r/” (p. 122). Contrary to lexical blocking, the effect of this kind of pattern blocking does not depend on words stored in the mental lexicon and their token frequency but on abstract features (in the case at hand, phonological features).
Blocking was first recognized by the Indian grammarian Pāṇini in the 5th or 4th century

Morphological case is conventionally defined as a system of marking of a dependent nominal for the type of relationship they bear to their heads. While most linguists would agree with this definition, in practice it is often a matter of controversy whether a certain marker X counts as case in language L, or how many case values language L features. First, the distinction between morphological cases and case particles/adpositions is fuzzy in a cross-linguistic perspective. Second, the distinctions between cases can be obscured by patterns of case syncretism, leading to different analyses of the underlying system. On the functional side, it is important to distinguish between syntactic (structural), semantic, and “pragmatic” cases, yet these distinctions are not clear-cut either, as syntactic cases historically arise from the two latter sources. Moreover, case paradigms of individual languages usually show a conflation between syntactic, semantic, and pragmatic cases (see the phenomenon of “focal ergativity,” where ergative case is used when the A argument is in focus). The composition of case paradigms can be shown to follow a certain typological pattern, which is captured by case hierarchy, as proposed by Greenberg and Blake, among others. Case hierarchy constrains the way how case systems evolve (or are reduced) across languages and derives from relative markedness and, ultimately, from frequencies of individual cases. The (one-dimensional) case hierarchy is, however, incapable of capturing all recurrent polysemies of individual case markers; rather, such polysemies can be represented through a more complex two-dimensional hierarchy (semantic map), which can also be given a diachronic interpretation.
Clinical linguistics is the branch of linguistics that applies linguistic concepts and theories to the study of language disorders. As the name suggests, clinical linguistics is a dual-facing discipline. Although the conceptual roots of this field are in linguistics, its domain of application is the vast array of clinical disorders that may compromise the use and understanding of language. Both dimensions of clinical linguistics can be addressed through an examination of specific linguistic deficits in individuals with neurodevelopmental disorders, craniofacial anomalies, adult-onset neurological impairments, psychiatric disorders, and neurodegenerative disorders. Clinical linguists are interested in the full range of linguistic deficits in these conditions, including phonetic deficits of children with cleft lip and palate, morphosyntactic errors in children with specific language impairment, and pragmatic language impairments in adults with schizophrenia.
Like many applied disciplines in linguistics, clinical linguistics sits at the intersection of a number of areas. The relationship of clinical linguistics to the study of communication disorders and to speech-language pathology (speech and language therapy in the United Kingdom) are two particularly important points of intersection. Speech-language pathology is the area of clinical practice that assesses and treats children and adults with communication disorders. All language disorders restrict an individual’s ability to communicate freely with others in a range of contexts and settings. So language disorders are first and foremost communication disorders. To understand language disorders, it is useful to think of them in terms of points of breakdown on a communication cycle that tracks the progress of a linguistic utterance from its conception in the mind of a speaker to its comprehension by a hearer. This cycle permits the introduction of a number of important distinctions in language pathology, such as the distinction between a receptive and an expressive language disorder, and between a developmental and an acquired language disorder. The cycle is also a useful model with which to conceptualize a range of communication disorders other than language disorders. These other disorders, which include hearing, voice, and fluency disorders, are also relevant to clinical linguistics.
Clinical linguistics draws on the conceptual resources of the full range of linguistic disciplines to describe and explain language disorders. These disciplines include phonetics, phonology, morphology, syntax, semantics, pragmatics, and discourse. Each of these linguistic disciplines contributes concepts and theories that can shed light on the nature of language disorder. A wide range of tools and approaches are used by clinical linguists and speech-language pathologists to assess, diagnose, and treat language disorders. They include the use of standardized and norm-referenced tests, communication checklists and profiles (some administered by clinicians, others by parents, teachers, and caregivers), and qualitative methods such as conversation analysis and discourse analysis. Finally, clinical linguists can contribute to debates about the nosology of language disorders. In order to do so, however, they must have an understanding of the place of language disorders in internationally recognized classification systems such as the 2013 Diagnostic and Statistical Manual of Mental Disorders (DSM-5) of the American Psychiatric Association.
Compound and complex predicates—predicates that consist of two or more lexical items and function as the predicate of a single sentence—present an important class of linguistic objects that pertain to an enormously wide range of issues in the interactions of morphology, phonology, syntax, and semantics. Japanese makes extensive use of compounding to expand a single verb into a complex one. These compounding processes range over multiple modules of the grammatical system, thus straddling the borders between morphology, syntax, phonology, and semantics. In terms of degree of phonological integration, two types of compound predicates can be distinguished. In the first type, called tight compound predicates, two elements from the native lexical stratum are tightly fused and inflect as a whole for tense. In this group, Verb-Verb compound verbs such as arai-nagasu [wash-let.flow] ‘to wash away’ and hare-agaru [sky.be.clear-go.up] ‘for the sky to clear up entirely’ are preponderant in numbers and productivity over Noun-Verb compound verbs such as tema-doru [time-take] ‘to take a lot of time (to finish).’
The second type, called loose compound predicates, takes the form of “Noun + Predicate (Verbal Noun [VN] or Adjectival Noun [AN]),” as in post-syntactic compounds like [sinsya : koonyuu] no okyakusama ([new.car : purchase] GEN customers) ‘customer(s) who purchase(d) a new car,’ where the symbol “:” stands for a short phonological break. Remarkably, loose compounding allows combinations of a transitive VN with its agent subject (external argument), as in [Supirubaagu : seisaku] no eiga ([Spielberg : produce] GEN film) ‘a film/films that Spielberg produces/produced’—a pattern that is illegitimate in tight compounds and has in fact been considered universally impossible in the world’s languages in verbal compounding and noun incorporation.
In addition to a huge variety of tight and loose compound predicates, Japanese has an additional class of syntactic constructions that as a whole function as complex predicates. Typical examples are the light verb construction, where a clause headed by a VN is followed by the light verb suru ‘do,’ as in Tomodati wa sinsya o koonyuu (sae) sita [friend TOP new.car ACC purchase (even) did] ‘My friend (even) bought a new car’ and the human physical attribute construction, as in Sensei wa aoi me o site-iru [teacher TOP blue eye ACC do-ing] ‘My teacher has blue eyes.’ In these constructions, the nominal phrases immediately preceding the verb suru are semantically characterized as indefinite and non-referential and reject syntactic operations such as movement and deletion. The semantic indefiniteness and syntactic immobility of the NPs involved are also observed with a construction composed of a human subject and the verb aru ‘be,’ as Gakkai ni wa oozei no sankasya ga atta ‘There was a large number of participants at the conference.’ The constellation of such “word-like” properties shared by these compound and complex predicates poses challenging problems for current theories of morphology-syntax-semantics interactions with regard to such topics as lexical integrity, morphological compounding, syntactic incorporation, semantic incorporation, pseudo-incorporation, and indefinite/non-referential NPs.

Compounding is a word formation process based on the combination of lexical elements (words or stems). In the theoretical literature, compounding is discussed controversially, and the disagreement also concerns basic issues. In the study of compounding, the questions guiding research can be grouped into four main areas, labeled here as delimitation, classification, formation, and interpretation. Depending on the perspective taken in the research, some of these may be highlighted or backgrounded.
In the delimitation of compounding, one question is how important it is to be able to determine for each expression unambiguously whether it is a compound or not. Compounding borders on syntax and on affixation. In some theoretical frameworks, it is not a problem to have more typical and less typical instances, without a precise boundary between them. However, if, for instance, word formation and syntax are strictly separated and compounding is in word formation, it is crucial to draw this borderline precisely. Another question is which types of criteria should be used to distinguish compounding from other phenomena. Criteria based on form, on syntactic properties, and on meaning have been used. In all cases, it is also controversial whether such criteria should be applied crosslinguistically.
In the classification of compounds, the question of how important the distinction between the classes is for the theory in which they are used poses itself in much the same way as the corresponding question for the delimitation. A common classification uses headedness as a basis. Other criteria are based on the forms of the elements that are combined (e.g., stem vs. word) or on the semantic relationship between the components. Again, whether these criteria can and should be applied crosslinguistically is controversial.
The issue of the formation rules for compounds is particularly prominent in frameworks that emphasize form-based properties of compounding. Rewrite rules for compounding have been proposed, generalizations over the selection of the input form (stem or word) and of linking elements, and rules for stress assignment. Compounds are generally thought of as consisting of two components, although these components may consist of more than one element themselves. For some types of compounds with three or more components, for example copulative compounds, a nonbinary structure has been proposed.
The question of interpretation can be approached from two opposite perspectives. In a semasiological perspective, the meaning of a compound emerges from the interpretation of a given form. In an onomasiological perspective, the meaning precedes the formation in the sense that a form is selected to name a particular concept. The central question in the interpretation of compounds is how to determine the relationship between the two components. The range of possible interpretations can be constrained by the rules of compounding, by the semantics of the components, and by the context of use. A much-debated question concerns the relative importance of these factors.
Construction Morphology is a theory of word structure in which the complex words of a language are analyzed as constructions, that is, systematic pairings of form and meaning. These pairings are analyzed within a Tripartite Parallel Architecture conception of grammar. This presupposes a word-based approach to the analysis of morphological structure and a strong dependence on paradigmatic relations between words. The lexicon contains both words and the constructional schemas they are instantiations of. Words and schemas are organized in a hierarchical network, with intermediate layers of subschemas. These schemas have a motivating function with respect to existing complex words and specify how new complex words can be formed.
The consequence of this view of morphology is that there is no sharp boundary between lexicon and grammar. In addition, the use of morphological patterns may also depend on specific syntactic constructions (construction-dependent morphology).
This theory of lexical relatedness also provides insight into language change such as the use of obsolete case markers as markers of specific constructions, the change of words into affixes, and the debonding of word constituents into independent words. Studies of language acquisition and word processing confirm this view of the lexicon and the nature of lexical knowledge.
Construction Morphology is also well equipped for dealing with inflection and the relationships between the cells of inflectional paradigms, because it can express how morphological schemas are related paradigmatically.

Despite its apparent formal simplicity, to define conversion as a word-formation technique is by no means a simple matter, even in respect of one language, let alone languages representing different typological groups or subgroups. The traditional claim that conversion is a derivationally unmarked word-class changing operation involving formally identical (homonymous) lexical items seems largely justifiable so far as English is concerned where this operation is exclusively word/lexeme-based (cf. to swap > (a) swap, clear > to clear). However, while this same claim is also true for Hungarian, a Finno-Ugric language (cf. este
To determine the linguistic nature of conversion and its place among other types of word formation is not a simple matter either, and, paradoxically, it is especially so in the case of the most extensively studied English conversion. The reasons for this to a great extent lie in the fact that practically each element of the traditional definition suggested in the previous paragraph has been called into question, giving rise to a diversity of interpretations of conversion not only in English, but also in a cross-linguistic perspective. Thus, if conversion is viewed as a kind of derivation, the assumptions can be made that being derivationally unmarked means either the presence of a zero formative, or, alternatively, the lack of any overt derivational marking on the converted item (consider for instance the English, Hungarian, German, and Old English examples above). Regardless of their long-debated justifiability, what these assumptions respectively suggest is that conversion after all should be treated either as a kind of derivation, namely zero derivation, or as a self-contained word-formation process different from derivation (affixation). In addition, being derivationally unmarked is also viewed in the corresponding literature as the absence of derivation altogether; and the suggestion is made that during conversion it is in effect the change in the inflectional paradigm that can only signal word-class shift. Because of this, so the argument goes, conversion should be seen as an inflectional and not as a derivational process.
The notion of word class itself and the uncertainties characterizing its understanding present further challenges to morphologists dealing with conversion. Concretely, it is a widely shared view that only the unmarked change of the entire word class can be recognized as conversion (see the examples above). However, there are opinions that insist that the change of a subclass or subcategory also qualifies as conversion, albeit partial or non-prototypical (cf. to run
Finally, treatments of conversion that focus on underlying semantic or conceptual motivations further add to the diversity of views of conversion. These treatments draw on the fact that there is a strong semantic link between the input and the output in the sense that normally the meaning of the latter is semantically derived (predictable) from that of the former. It is argued that this semantic link between the pair words of conversion is based on various types of conceptual, predominantly metonymic shifts whereby extralinguistic entities such as actions, instruments, properties, natural kinds, etc., undergo cognitive reanalyses (cf. instrument as action, property as action, action as actor/place) driven by the communicative needs of interlocutors. Consequently, along with the interpretations mentioned in the previous paragraphs, conversion can also be considered a word-formation process motivated by different types of conceptual shifts between formally identical input and output items.
Morphological defectiveness refers to situations where one or more paradigmatic forms of a lexeme are not realized, without plausible syntactic, semantic, or phonological causes. The phenomenon tends to be associated with low-frequency lexemes and loanwords. Typically, defectiveness is gradient, lexeme-specific, and sensitive to the internal structure of paradigms.
The existence of defectiveness is a challenge to acquisition models and morphological theories where there are elsewhere operations to materialize items. For this reason, defectiveness has become a rich field of research in recent years, with distinct approaches that view it as an item-specific idiosyncrasy, as an epiphenomenal result of rule competition, or as a normal morphological alternation within a paradigmatic space.
Derivational morphology is a type of word formation that creates new lexemes, either by changing syntactic category or by adding substantial new meaning (or both) to a free or bound base. Derivation may be contrasted with inflection on the one hand or with compounding on the other. The distinctions between derivation and inflection and between derivation and compounding, however, are not always clear-cut. New words may be derived by a variety of formal means including affixation, reduplication, internal modification of various sorts, subtraction, and conversion. Affixation is best attested cross-linguistically, especially prefixation and suffixation. Reduplication is also widely found, with various internal changes like ablaut and root and pattern derivation less common. Derived words may fit into a number of semantic categories. For nouns, event and result, personal and participant, collective and abstract noun are frequent. For verbs, causative and applicative categories are well-attested, as are relational and qualitative derivations for adjectives. Languages frequently also have ways of deriving negatives, relational words, and evaluatives. Most languages have derivation of some sort, although there are languages that rely more heavily on compounding than on derivation to build their lexical stock. A number of topics have dominated the theoretical literature on derivation, including productivity (the extent to which new words can be created with a given affix or morphological process), the principles that determine the ordering of affixes, and the place of derivational morphology with respect to other components of the grammar. The study of derivation has also been important in a number of psycholinguistic debates concerning the perception and production of language.

Distributed Morphology (DM) is a framework in theoretical morphology, characterized by two core tenets: (i) that the internal hierarchical structure of words is, in the first instance, syntactic (complex words are derived syntactically), and (ii) that the syntax operates on abstract morphemes, defined in terms of morphosyntactic features, and that the spell-out (realization, exponence) of these abstract morphemes occurs after the syntax. Distributing the functions of the classical morpheme in this way allows for analysis of mismatches between the minimal units of grammatical combination and the minimal units of sound. Much work within the framework is nevertheless guided by seeking to understand restrictions on such mismatches, balancing the need for the detailed description of complex morphological data in individual languages against an attempt to explain broad patterns in terms of restrictions imposed by grammatical principles.
In the Early Modern English period (1500–1700), steps were taken toward Standard English, and this was also the time when Shakespeare wrote, but these perspectives are only part of the bigger picture. This chapter looks at Early Modern English as a variable and changing language not unlike English today. Standardization is found particularly in spelling, and new vocabulary was created as a result of the spread of English into various professional and occupational specializations. New research using digital corpora, dictionaries, and databases reveals the gradual nature of these processes. Ongoing developments were no less gradual in pronunciation, with processes such as the Great Vowel Shift, or in grammar, where many changes resulted in new means of expression and greater transparency. Word order was also subject to gradual change, becoming more fixed over time.
Evaluative morphology is a field of linguistic studies that deals with the formation of diminutives, augmentatives, pejoratives, and amelioratives. Actually, evaluative constructions cross the boundaries of morphology, and are sometimes realized by formal strategies that cannot be numbered among word formation processes. Nevertheless, morphology plays a dominant role in the formation of evaluatives. The first attempt to draw an exhaustive account of this set of complex forms is found in the 1984 work Generative Morphology, by Sergio Scalise, who made the hypothesis that evaluatives represent a separate block of rules between inflection and derivation. This hypothesis is based on the fact that evaluatives show some properties that are derivational, others that are inflectional, and some specific properties that are neither derivational nor inflectional. After Scalise’s proposal, almost all scholars have tried to answer the question concerning the place of evaluative rules within the morphological component. What data reveal is that, in a cross-linguistic perspective, evaluatives display a uniform behavior from a semantic and functional point of view, but exhibit a wide range of formal properties. In other words, functional identity does not imply formal identity; consequently, we can expect that constructions performing the same function display different formal properties in different languages. So, if evaluatives are undoubtedly derivational in most Indo-European languages (even if they cannot be considered a typical example of derivation), they are certainly quite close to inflection in some Bantu languages. This means that the question about the place of evaluatives within the morphological component probably is not as crucial as scholars have thought, and that other issues, sometimes neglected in the literature, deserve the same attention. Among them, the role of pragmatics in the description of evaluatives is no doubt central. According to Dressler and Merlini Barbaresi, in their 1994 work, Morphopragmatics: Diminutives and Intensifiers in Italian, German and Other Languages, evaluative constructions are the more typical instantiation of morphopragmatics, which is “defined as the area of general pragmatic meanings of morphological rules, that is of the regular pragmatic effects produced when moving from the input to the output of a morphological rule.” Evaluatives include “a pragmatic variable which cannot be suppressed in the description of [their] meaning.” Another central issue in studies on evaluative morphology is the wide set of semantic nuances that usually accompany diminutives, augmentatives, pejoratives, and amelioratives. For example, a diminutive form can occasionally assume a value that is attenuative, singulative, partitive, appreciative, affectionate, etc. This cluster of semantic values has often increased the idea that evaluatives are irregular in nature and that they irremediably avoid any generalization. Dan Jurafsky showed, in 1996, that these different meanings are often the outcome of regular and cross-linguistically recurrent semantic processes, both in a synchronic and in a diachronic perspective.
This article revisits Grimshaw's (1990) tripartition of nominalization, which introduced an important correlation between particular types of nominalization and the readings associated with these nominal forms, Event and Referential. The article discusses criteria that may be used to distinguish between the two readings and the limitations of these criteria. It further offers a selective discussion of how different approaches to nominalization implement Event and Referential readings.
A fundamental difference in theoretical models of morphology and, particularly, of the syntax–morphology interface is that between endoskeletal and exoskeletal approaches. In the former, more traditional, endoskeletal approaches, open-class lexical items like cat or sing are held to be inherently endowed with a series of formal features that determine the properties of the linguistic expressions in which they appear. In the latter, more recent, exoskeletal approaches, it is rather the morphosyntactic configurations, independently produced by the combination of abstract functional elements, that determine those properties. Lexical items, in this latter approach, are part of the structure but, crucially, do not determine it.
Conceptually, although a correlation is usually made between endoskeletalism and lexicalism/projectionism, on the one hand, and between exoskeletalism and (neo)constructionism, on the other, things are actually more complicated, and some frameworks exist that seem to challenge those correlations, in particular when the difference between word and morpheme is taken into account.
Empirically, the difference between these two approaches to morphology and the morphology-syntax interface comes to light when one examines how each one treats a diversity of word-related phenomena: morphosyntactic category and category shift in derivational processes, inflectional class, nominal properties like mass or count, and verbal properties like agentivity and (a)telicity.

Until recently, theoretical linguists have paid little attention to the frequency of linguistic elements in grammar and grammatical development. It is a standard assumption of (most) grammatical theories that the study of grammar (or competence) must be separated from the study of language use (or performance). However, this view of language has been called into question by various strands of research that have emphasized the importance of frequency for the analysis of linguistic structure. In this research, linguistic structure is often characterized as an emergent phenomenon shaped by general cognitive processes such as analogy, categorization, and automatization, which are crucially influenced by frequency of occurrence.
There are many different ways in which frequency affects the processing and development of linguistic structure. Historical linguists have shown that frequent strings of linguistic elements are prone to undergo phonetic reduction and coalescence, and that frequent expressions and constructions are more resistant to structure mapping and analogical leveling than infrequent ones. Cognitive linguists have argued that the organization of constituent structure and embedding is based on the language users’ experience with linguistic sequences, and that the productivity of grammatical schemas or rules is determined by the combined effect of frequency and similarity. Child language researchers have demonstrated that frequency of occurrence plays an important role in the segmentation of the speech stream and the acquisition of syntactic categories, and that the statistical properties of the ambient language are much more regular than commonly assumed. And finally, psycholinguists have shown that structural ambiguities in sentence processing can often be resolved by lexical and structural frequencies, and that speakers’ choices between alternative constructions in language production are related to their experience with particular linguistic forms and meanings. Taken together, this research suggests that our knowledge of grammar is grounded in experience.
Linguistic change not only affects the lexicon and the phonology of words, it also operates on the grammar of a language. In this context, grammaticalization is concerned with the development of lexical items into markers of grammatical categories or, more generally, with the development of markers used for procedural cueing of abstract relationships out of linguistic items with concrete referential meaning. A well-known example is the English verb go in its function of a future marker, as in She is going to visit her friend. Phenomena like these are very frequent across the world’s languages and across many different domains of grammatical categories. In the last 50 years, research on grammaticalization has come up with a plethora of (a) generalizations, (b) models of how grammaticalization works, and (c) methodological refinements.
On (a): Processes of grammaticalization develop gradually, step by step, and the sequence of the individual stages follows certain clines as they have been generalized from cross-linguistic comparison (unidirectionality). Even though there are counterexamples that go against the directionality of various clines, their number seems smaller than assumed in the late 1990s.
On (b): Models or scenarios of grammaticalization integrate various factors. Depending on the theoretical background, grammaticalization and its results are motivated either by the competing motivations of economy vs. iconicity/explicitness in functional typology or by a change from movement to merger in the minimalist program. Pragmatic inference is of central importance for initiating processes of grammaticalization (and maybe also at later stages), and it activates mechanisms like reanalysis and analogy, whose status is controversial in the literature. Finally, grammaticalization does not only work within individual languages/varieties, it also operates across languages. In situations of contact, the existence of a certain grammatical category may induce grammaticalization in another language.
On (c): Even though it is hard to measure degrees of grammaticalization in terms of absolute and exact figures, it is possible to determine relative degrees of grammaticalization in terms of the autonomy of linguistic signs. Moreover, more recent research has come up with criteria for distinguishing grammaticalization and lexicalization (defined as the loss of productivity, transparency, and/or compositionality of former productive, transparent, and compositional structures).
In spite of these findings, there are still quite a number of questions that need further research. Two questions to be discussed address basic issues concerning the overall properties of grammaticalization. (1) What is the relation between constructions and grammaticalization? In the more traditional view, constructions are seen as the syntactic framework within which linguistic items are grammaticalized. In more recent approaches based on construction grammar, constructions are defined as combinations of form and meaning. Thus, grammaticalization can be seen in the light of constructionalization, i.e., the creation of new combinations of form and meaning. Even though constructionalization covers many apects of grammaticalization, it does not exhaustively cover the domain of grammaticalization. (2) Is grammaticalization cross-linguistically homogeneous, or is there a certain range of variation? There is evidence from East and mainland Southeast Asia that there is cross-linguistic variation to some extent.
While in phonology Middle Indo-Aryan (MIA) dialects preserved the phonological system of Old Indo-Aryan (OIA) virtually intact, their morphosyntax underwent far-reaching changes, which altered fundamentally the synthetic morphology of earlier Prākrits in the direction of the analytic typology of New Indo-Aryan (NIA). Speaking holistically, the “accusative alignment” of OIA (Vedic Sanskrit) was restructured as an “ergative alignment” in Western IA languages, and it is precisely during the Late MIA period (ca. 5th–12th centuries
(a) We shall start with the restructuring of the nominal case system in terms of the reduction of the number of cases from seven to four. This phonologically motivated process resulted ultimately in the rise of the binary distinction of the “absolutive” versus “oblique” case at the end of the MIA period). (b) The crucial role of animacy in the restructuring of the pronominal system and the rise of the “double-oblique” system in Ardha-Māgadhī and Western Apabhramśa will be explicated. (c) In the verbal system we witness complete remodeling of the aspectual system as a consequence of the loss of earlier synthetic forms expressing the perfective (Aorist) and “retrospective” (Perfect) aspect. Early Prākrits (Pāli) preserved their sigmatic Aorists (and the sigmatic Future) until late MIA centuries, while on the Iranian side the loss of the “sigmatic” aorist was accelerated in Middle Persian by the “weakening” of s > h > Ø. (d) The development and the establishment of “ergative alignment” at the end of the MIA period will be presented as a consequence of the above typological changes: the rise of the “absolutive” vs. “oblique” case system; the loss of the finite morphology of the perfective and retrospective aspect; and the recreation of the aspectual contrast of perfectivity by means of quasinominal (participial) forms. (e) Concurrently with the development toward the analyticity in grammatical aspect, we witness the evolution of lexical aspect (Aktionsart) ushering in the florescence of “serial” verbs in New Indo-Aryan.
On the whole, a contingency view of alignment considers the increase in ergativity as a by-product of the restoration of the OIA aspectual triad: Imperfective–Perfective–Perfect (in morphological terms Present–Aorist–Perfect). The NIA Perfective and Perfect are aligned ergatively, while their finite OIA ancestors (Aorist and Perfect) were aligned accusatively. Detailed linguistic analysis of Middle Indo-Aryan texts offers us a unique opportunity for a deeper comprehension of the formative period of the NIA state of affairs.
