Noam Avram Chomsky is one of the central figures of modern linguistics. He was born in Philadelphia, Pennsylvania on December 7, 1928. In 1945, Chomsky enrolled in the University of Pennsylvania, where he met Zellig Harris (1909–1992), a leading Structuralist, through their shared political interests. His first encounter with Harris’s work was when he proof-read Harris’s book Methods in Structural Linguistics, published in 1951 but completed already in 1947. Chomsky grew dissatisfied with Structuralism and started to develop his own major idea that syntax and phonology are in part matters of abstract representations. This was soon combined with a psychobiological view of language as a unique part of the mind/brain.
Chomsky spent 1951–1955 as a Junior Fellow of the Harvard Society of Fellows, after which he joined the faculty at MIT under the sponsorship of Morris Halle. He was promoted to full professor of Foreign Languages and Linguistics in 1961, appointed Ferrari Ward Professor of Linguistics in 1966, and Institute Professor in 1976, retiring in 2002. Chomsky is still remarkably active, publishing, teaching, and lecturing across the world.
In 1967, both the University of Chicago and the University of London awarded him honorary degrees, and since then he has been the recipient of scores of honors and awards. In 1988, he was awarded the Kyoto Prize in basic science, created in 1984 in order to recognize work in areas not included among the Nobel Prizes. These honors are all a testimony to Chomsky’s influence and impact in linguistics and cognitive science more generally over the past 60 years. His contributions have of course also been heavily criticized, but nevertheless remain crucial to investigations of language.
Chomsky’s work has always centered around the same basic questions and assumptions, especially that human language is an inherent property of the human mind. The technical part of his research has continuously been revised and updated. In the 1960s phrase structure grammars were developed into what is known as the Standard Theory, which transformed into the Extended Standard Theory and X-bar theory in the 1970s. A major transition occurred at the end of the 1970s, when the Principles and Parameters Theory emerged. This theory provides a new understanding of the human language faculty, focusing on the invariant principles common to all human languages and the points of variation known as parameters. Its recent variant, the Minimalist Program, pushes the approach even further in asking why grammars are structured the way they are.
Nominalization refers both to the process by which complex nouns are created and to the complex nouns that are derived by that process. Nominalizations common in the languages of the world include event/result nouns, personal or participant nouns (agent, patient, location, etc.), as well as collectives and abstracts. It is common for nominalizations to be highly polysemous. Theoretical issues concerning nominalization typically stem from the question of how to account for this pervasive polysemy. Within generative grammar, both syntactic and lexicalist approaches have been proposed. The issue of polysemy in nominalization has also been of interest within cognitive and functional frameworks. The article considers, finally, the extent to which nominalization is subject to competition and blocking.
Nominal reference is central to both linguistic semantics and philosophy of language. On the theoretical side, both philosophers and linguists wrestle with the problem of how the link between nominal expressions and their referents is to be characterized, and what formal tools are most appropriate to deal with this issue. The problem is complex because nominal expression come in a large variety of forms, from simple proper names, pronouns, or bare nouns (Jennifer, they, books) to complex expressions involving determiners and various quantifiers (the/every/no/their answer). While the reference of such expressions is varied, their basic syntactic distribution as subjects or objects of various types, for instance, is homogeneous. Important advances in understanding this tension were made with the advent of the work of R. Montague and that of his successors. The problems involved in understanding the relationship between pronouns and their antecedents in discourse have led to another fundamental theoretical development, namely that of dynamic semantics. On the empirical side, issues at the center of both linguistic and philosophical investigations concern how to best characterize the difference between definite and indefinite nominals, and, more generally, how to understand the large variety of determiner types found both within a language and cross-linguistically. These considerations led to refining the definite/indefinite contrast to include fine-grained specificity distinctions that have been shown to be relevant to various morphosyntactic phenomena across the world’s languages. Considerations concerning nominal reference are thus relevant not only to semantics but also to morphology and syntax. Some questions within the domain of nominal reference have grown into rich subfields of inquiry. This is the case with generic reference, the study of pronominal reference, the study of quantifiers, and the study of the semantics of nominal number marking.
The noun-modifying clause construction (NMCC) in Japanese is a complex noun phrase in which a prenominal clause is dependent on the head noun. Naturally occurring instances of the construction demonstrate that a single structure, schematized as [[… predicate (finite/adnominal)] Noun], represents a wide range of semantic relations between the head noun and the dependent clause, encompassing some that would be expressed by structurally distinct constructions such as relative clauses, noun complement clauses, and other types of complex noun phrases in other languages, such as English. In that way, the Japanese NMCC demonstrates a clear case of the general noun-modifying construction (GNMCC), that is, an NMCC that has structural uniformity across interpretations that extend beyond the range of relative clauses.
One of the notable properties of the Japanese NMCC is that the modifying clause may consist only of the predicate, reflecting the fact that referential density is moderate in Japanese—arguments of a predicate are not required to be overtly expressed either in the main clause or in the modifying clause. Another property of the Japanese NMCC is that there is no explicit marking in the construction that indicates the grammatical or semantic relation between the head noun and the modifying clause. The two major constituents are simply juxtaposed to each other.
Successful construal of the intended interpretations of instances of such a construction, in the absence of explicit markings, likely relies on an aggregate of structural, semantic, and pragmatic factors, including the semantic content of the linguistic elements, verb valence information, and the interpreter’s real-world knowledge, in addition to the basic structural information.
Researchers with different theoretical approaches have studied Japanese NMCCs or subsets thereof. Syntactic approaches, inspired by generative grammar, have focused mostly on relative clauses and aimed to identify universally recognized syntactic principles. Studies that take the descriptive approach have focused on detailed descriptions and the classification of a wide spectrum of naturally occurring instances of the construction in Japanese. The third and most recent group of studies has emphasized the importance of semantics and pragmatics in accounting for a wide variety of naturally occurring instances.
The examination of Japanese NMCCs provides information about the nature of clausal noun modification and affords insights into languages beyond Japanese, as similar phenomena have reportedly been observed crosslinguistically to varying degrees.
Number is the category through which languages express information about the individuality, numerosity, and part structure of what we speak about. As a linguistic category it has a morphological, a morphosyntactic, and a semantic dimension, which are variously interrelated across language systems. Number marking can apply to a more or less restricted part of the lexicon of a language, being most likely on personal pronouns and human/animate nouns, and least on inanimate nouns. In the core contrast, number allows languages to refer to ‘many’ through the description of ‘one’; the sets referred to consist of tokens of the same type, but also of similar types, or of elements pragmatically associated with one named individual. In other cases, number opposes a reading of ‘one’ to a reading as ‘not one,’ which includes masses; when the ‘one’ reading is morphologically derived from the ‘not one,’ it is called a singulative. It is rare for a language to have no linguistic number at all, since a ‘one–many’ opposition is typically implied at least in pronouns, where the category of person discriminates the speaker as ‘one.’ Beyond pronouns, number is typically a property of nouns and/or determiners, although it can appear on other word classes by agreement. Verbs can also express part-structural properties of events, but this ‘verbal number’ is not isomorphic to nominal number marking. Many languages allow a variable proportion of their nominals to appear in a ‘general’ form, which expresses no number information. The main values of number-marked elements are singular and plural; dual and a much rarer trial also exist. Many languages also distinguish forms interpreted as paucals or as greater plurals, respectively, for small and usually cohesive groups and for generically large ones. A broad range of exponence patterns can express these contrasts, depending on the morphological profile of a language, from word inflections to freestanding or clitic forms; certain choices of classifiers also express readings that can be described as ‘plural,’ at least in certain interpretations. Classifiers can co-occur with other plurality markers, but not when these are obligatory as expressions of an inflectional paradigm, although this is debated, partly because the notion of classifier itself subsumes distinct phenomena. Many languages, especially those with classifiers, encode number not as an inflectional category, but through word-formation operations that express readings associated with plurality, including large size. Current research on number concerns all its morphological, morphosyntactic, and semantic dimensions, in particular the interrelations of them as part of the study of natural language typology and of the formal analysis of nominal phrases. The grammatical and semantic function of number and plurality are particularly prominent in formal semantics and in syntactic theory.
Within the Ryukyuan branch of the Japonic family of languages, present-day Okinawan retains numerous regional variants which have evolved for over a thousand years in the Ryukyuan Archipelago. Okinawan is one of the six Ryukyuan languages that UNESCO identified as endangered. One of the theoretically fascinating features is that there is substantial evidence for establishing a high central phonemic vowel in Okinawan although there is currently no overt surface [ï]. Moreover, the word-initial glottal stop [ʔ] in Okinawan is more salient than that in Japanese when followed by vowels, enabling recognition that all Okinawan words are consonant-initial. Except for a few particles, all Okinawan words are composed of two or more morae. Suffixation or vowel lengthening (on nouns, verbs, and adjectives) provides the means for signifying persons as well as things related to human consumption or production. Every finite verb in Okinawan terminates with a mood element. Okinawan exhibits a complex interplay of mood or negative elements and focusing particles. Evidentiality is also realized as an obligatory verbal suffix.
Old and Middle Japanese are the pre-modern periods of the attested history of the Japanese language. Old Japanese (OJ) is largely the language of the 8th century, with a modest, but still significant number of written sources, most of which is poetry. Middle Japanese is divided into two distinct periods, Early Middle Japanese (EMJ, 800–1200) and Late Middle Japanese (LMJ, 1200–1600). EMJ saw most of the significant sound changes that took place in the language, as well as profound influence from Chinese, whereas most grammatical changes took place between the end of EMJ and the end of LMJ. By the end of LMJ, the Japanese language had reached a form that is not significantly different from present-day Japanese.
OJ phonology was simple, both in terms of phoneme inventory and syllable structure, with a total of only 88 different syllables. In EMJ, the language became quantity sensitive, with the introduction of a long versus short syllables. OJ and EMJ had obligatory verb inflection for a number of modal and syntactic categories (including an important distinction between a conclusive and an (ad)nominalizing form), whereas the expression of aspect and tense was optional. Through late EMJ and LMJ this system changed completely to one without nominalizing inflection, but obligatory inflection for tense.
The morphological pronominal system of OJ was lost in EMJ, which developed a range of lexical and lexically based terms of speaker and hearer reference. OJ had a two-way (speaker–nonspeaker) demonstrative system, which in EMJ was replaced by a three-way (proximal–mesial–distal) system.
OJ had a system of differential object marking, based on specificity, as well as a word order rule that placed accusative marked objects before most subjects; both of these features were lost in EMJ. OJ and EMJ had genitive subject marking in subordinate clauses and in focused, interrogative and exclamative main clauses, but no case marking of subjects in declarative, optative, or imperative main clauses and no nominative marker. Through LMJ genitive subject marking was gradually circumscribed and a nominative case particle was acquired which could mark subjects in all types of clauses.
OJ had a well-developed system of complex predicates, in which two verbs jointly formed the predicate of a single clause, which is the source of the LMJ and NJ (Modern Japanese) verb–verb compound complex predicates. OJ and EMJ also had mono-clausal focus constructions that functionally were similar to clefts in English; these constructions were lost in LMJ.

The onomasiological approach is a theoretical framework that emphasizes the cognitive-semantic component of language and the primacy of extralinguistic reality in the process of naming. With a tangible background in the functional perspective of the Prague School of Linguistics, this approach believes that name giving is essentially governed by the needs of language users, and hence assigns a subordinate role to the traditional levels of linguistic description. This stance characterizes the onomasiological framework in opposition to other theories of language, for example, structuralism or generativism, which first tackle the form of linguistic material and then move on to meaning.
The late 20th and early 21st centuries have witnessed the emergence of several cognitive-onomasiological models, all of which share an extensive use of semantic categories as working units and a particular interest in the area of word formation. Despite a number of divergences, such proposals all confront mainstream morphological research by heavily revising conventional concepts and introducing model-specific terminology regarding, for instance, the independent character of the lexicon, the (non-)regularity of word-formation processes or their understanding of morphological productivity. The result is a small set of models that have earned a pivotal position as an alternative to dominant theories of word formation.
The Northeast Asia is one of the unique points on the globe where there are many language isolates and portmanteau families. From a conservative point of view, the Japanese language is a member of such a portmanteau family that has recently and increasingly been called Japonic in the Western literature. While Japanese is unquestionably a member of this Japonic language family, which consists of two Japanese languages (Japanese itself and the moribund Hachijō language) and four or five relatively closely related Ryūkyūan languages (Amami, Okinawan, Miyako, Yaeyama, and possibly Yonaguni), attempts have also been made to establish a genetic relationship between Japanese and various other language families. Most of these attempts have been amateurish, a major exception being the Koreo-Japonic hypothesis, which still remains unproven as well. It is also quite likely that the Japonic language family (or, more precisely, Insular Japonic) is the only linguistic grouping whose genetic relationship can be established beyond any doubt. A genetic relationship is also likely to exist between Japonic and a number of fragmentarily attested languages that once flourished in the south and center of the Korean Peninsula, but that died out no later than 9th century A.D. The paucity of material available does not allow one to establish solid predictive-productive regular correspondences in many cases, but intuitively the genetic relationship seems to be a matter of fact. Anything beyond intuition, however, lies in the realm of conjecture and speculation. The alleged Koreo-Japonic relationship is best explained by a centuries-long contact relationship rather than by common origin, given such factors as the virtual absence of any kind of shared paradigmatic morphology, as well as by multiple problems in establishing the real (and not imaginable or made-to-fit) regular correspondences. The Japanese-“Altaic” hypothesis is even more speculative and far-fetched. Consequently, the conclusion is that the Japanese language or the Japonic language family has no demonstrable relationship with any other language family or language isolate on the planet.
Relative clauses of which the predicate contains a present, past, or passive participle can be used in a reduced form. Although it has been shown that participial relative clauses cannot always be considered to be non-complete variants of full relative clauses, they are generally called reduced relative clauses in the literature. Since they differ from full relative clauses in containing a non-finite predicate, they are also called non-finite relative clauses. Another type of non-finite relative clause is the infinitival relative clause. In English, in participial relative clauses, the antecedent noun is interpreted as the subject of the predicate of the relative clause. Because of this restriction, the status of relative clause has been put into doubt for participial adnominal modifiers, especially, because in a language such as English, they can occur in pre-nominal position, whereas a full relative clause cannot. While some linguists analyze both pre-nominal and post-nominal participles as verbal, others have argued that participles are essentially adjectival categories. In a third type of analysis, participles are divided into verbal and adjectival ones. This also holds for adnominal participles. Besides the relation to full relative clauses and the category of the participle, participial relative clauses raise a number of other interesting questions, which have been discussed in the literature. These questions concern the similarity or difference in interpretation of the pre-nominal and the post-nominal participial clause, restrictions on the type of verb used in past participial relative clauses, and similarities and differences between the syntax and semantics of participial clauses in English and other languages. Besides syntactic and semantic issues, participial relative clauses have raised other questions, such as their use in texts. Participial relative clauses have been studied from a diachronic and a stylistic point of view. It has been shown that the use of reduced forms such as participial relative clauses has increased over time and that, because of their condensed form, they are used more in academic styles than in colloquial speech. Nonetheless, they have proven to be used already by very young children, although in second language acquisition they are used late, because their condensed form is associated with an academic style of writing. Since passive or past participles often have the same form as the past tense, it has been shown that sentences containing a subject noun modified by a post-nominal past or passive participle are difficult to process, although certain factors may facilitate the processing of the sentence.
Cross-linguistic differences in passive formation and the differences between verbal and adjectival passives reveal some of the core properties of the passive. In earlier stages of the Principles and Parameters framework, differences in both these domains were taken as evidence that the grammar has two distinct components to build passives, namely the lexicon and the syntax. This intuition can be restated by adopting the view that all passive formation is syntactic. Indeed, it has been posited that there are two syntactic domains to build passives, and these two domains correlate with distinct properties of passive formations within a language and across languages.

The Penutian language family, Penutian phylum, or better still, Penutian hypothesis is one of the largest genealogical linguistic groupings to have been proposed for western North America. It involves 16 families or isolates. Only a few of these families are demonstrably relatable to one another according to current knowledge and diachronic techniques. Sometimes Penutian is split by observers into groups of languages assumed to be interrelated, and this is done without assumptions that the groups themselves are interrelated.
This article focuses on the Canadian and US languages in “Sapir’s Penutian,” the most commonly accepted version; the most southerly family within Penutian is thus held as Yokutsan of California’s Sierra Nevada. It discusses the subclassification of the so-called Penutian languages into families and smaller units; aspects of their phonology, morphosyntax, and contact histories; and issues in their revitalization and the potential reconstruction of Proto-Penutian.

As far as personal nouns are concerned, an agent noun is a derived noun whose general meaning is “person who usually/typically does . . .”. It is thus characterized by the feature [+ Human], irrespective of the fact that the person involved actually performs an action (e.g., French nageur “swimmer,” i.e., “a person who swims”), carries on a profession (e.g., Spanish carpintero “carpenter,” i.e., “a person who builds or repairs wooden structures”), adheres to a certain ideology or group (e.g., Italian femminista “feminist,” i.e., “a person who supports or follows the feminist movement”), etc.
Agent nouns can be both denominal and deverbal. Latin denominal agent nouns were mainly formed with –ARIUS, though the Latin agentive suffix par excellence was –TOR, which derived nouns from verbs. The reflexes of both –ARIUS and –TOR are widespread and highly productive in Romance: For the former, see Portuguese –eiro / –ario, Spanish –ero / –ario, Catalan –er, French –ier / –aire, Italian –aio / –aro / –ario, Romanian –ar, etc.; for the latter, Portuguese, Spanish, Catalan –dor, French –eur, Italian –tore, Romanian –tor, etc. At any rate, the distinction between denominal and deverbal agent nouns is not always straightforward, as is shown by the Romance forms connected with Latin present particle –NTE: Whereas most of them display a verbal base (see, e.g., Italian cantante “singer” ← cantare “to sing”), some others do not (see, e.g., Italian bracciante “hired hand” ← braccio “arm”), allowing them to be regarded as denominal derivations.
The distribution of agentive suffixes in Romance is sometimes conditioned by borrowing phenomena. For example, Italian –iere is not a direct outcome of Latin –ARIUS, but rather a borrowing from French –ier; Sardinian –eri is of Spanish/Catalan origin, whereas Piedmontese –aire and –eur are loans from Occitan and French, respectively.
A theoretical issue that is related to agent nouns in Romance is the so-called agent-instrument-locative polysemy. While traditionally attributed to the result of metaphorical and/or semantic extensions, this polysemy is better explained by such factors as homonymization, ellipsis, analogy, borrowing/calque, though, at least in some cases, we cannot exclude that a combination of both explanation types has taken place.

Babbling is made up of meaningless speechlike syllables called canonical syllables. Canonical syllables are characterized by the coordination of consonantal and vocalic elements in syllables that have speechlike timing, phonation, and resonance characteristics. Infants begin to babble on average at approximately seven months of age. Babbling continues in parallel with less mature noncanonical vocalizations that make up the majority of utterances through the first year. Babbling also continues in parallel with the emergence of meaningful speech during the second year. Regardless of the language that the infant is learning, most canonical syllables have a CV shape with the consonant being a labial or alveolar stop or nasal and the vowel most likely to be central or low- to mid-front in place (e.g., [bʌ], [da], [mæ]). Approximately 15% of canonical utterances consist of multisyllable strings; in other words, most babbled utterances contain only a single CV syllable. The onset of the canonical babbling stage is crucially dependent upon normal hearing, permitting access to language input and feedback of self-produced speech. Many studies have reported differences in the phonetic and acoustic characteristics of babble produced by infants learning different languages. These differences include the frequency with which certain consonants are produced, the location, size, and shape of the vowel space, and the rhythmic and intonation qualities of multisyllable babbles, in each case reflecting specificities of the input language. However, replications of these findings are rare and further research is required to better understand the learning mechanisms that underlie language specific acquisition of articulatory representations during the prelinguistic stage of vocal development.
The function of the voice organ is basically the same in classical singing as in speech. However, loud orchestral accompaniment has necessitated the use of the voice in an economical way. As a consequence, the vowel sounds tend to deviate considerably from those in speech. Male voices cluster formant three, four, and five, so that a marked peak is produced in spectrum envelope near 3,000 Hz. This helps them to get heard through a loud orchestral accompaniment. They seem to achieve this effect by widening the lower pharynx, which makes the vowels more centralized than in speech. Singers often sing at fundamental frequencies higher than the normal first formant frequency of the vowel in the lyrics. In such cases they raise the first formant frequency so that it gets somewhat higher than the fundamental frequency. This is achieved by reducing the degree of vocal tract constriction or by widening the lip and jaw openings, constricting the vocal tract in the pharyngeal end and widening it in the mouth. These deviations from speech cause difficulties in vowel identification, particularly at high fundamental frequencies. Actually, vowel identification is almost impossible above 700 Hz (pitch F5).
Another great difference between vocal sound produced in speech and the classical singing tradition concerns female voices, which need to reduce the timbral differences between voice registers. Females normally speak in modal or chest register, and the transition to falsetto tends to happen somewhere above 350 Hz. The great timbral differences between these registers are avoided by establishing control over the register function, that is, over the vocal fold vibration characteristics, so that seamless transitions are achieved.
In many other respects, there are more or less close similarities between speech and singing. Thus, marking phrase structure, emphasizing important events, and emotional coloring are common principles, which may make vocal artists deviate considerably from the score’s nominal description of fundamental frequency and syllable duration.

Speech sounds are commonly divided into two main categories in human languages: vowels, such as ‘e’, ‘a’, ‘o’, and consonants, such as ‘k’, ‘n’, ‘s’. This division is made on the basis of both phonetic and phonological principles, which is useful from a general linguistic point of view but problematic for detailed description and analysis. The main differences between vowels and consonants are that (1) vowels are sounds produced with an open airway between the larynx and the lips, at least along the midline, whereas consonants are produced with a stricture or closure somewhere along it; and (2) that vowels tend to be syllabic in languages, meaning that they embody a sonorous peak in a syllable, whereas only some kinds of consonants tend to be syllabic. There are two main physical components needed to produce a vowel: a sound source, typically a tone produced by vocal fold vibration at the larynx, and a resonator, typically the upper airways. When the tone resonates in the upper airways, it gets a specific quality of sound, perceived and interpreted as a vowel quality, for example, ‘e’ or ‘a’. Which vowel quality is produced is determined by the shape of the inner space of the throat and mouth, the vocal tract shape, created by the speaker’s configuration of the articulators, which include the lips, tongue, jaw, hard and soft palate, pharynx, and larynx. Which vowel is perceived is determined by the auditory and visual input as well as by the listener’s expectations and language experience. Diachronic and synchronic studies on vowel typology show main trends in the vowel inventories in the worlds’ languages, which can be associated with human phonetic aptitude.
Reduplication is a word-formation process in which all or part of a word is repeated to convey some form of meaning. A wide range of patterns are found in terms of both the form and meaning expressed by reduplication, making it one of the most studied phenomenon in phonology and morphology. Because the form always varies, depending on the base to which it is attached, it raises many issues such as the nature of the repetition mechanism, how to represent reduplicative morphemes, and whether or not a unified approach can be proposed to account for the full range of patterns.

Child phonological templates are idiosyncratic word production patterns. They can be understood as deriving, through generalization of patterning, from the very first words of the child, which are typically close in form to their adult targets. Templates can generally be identified only some time after a child’s first 20–50 words have been produced but before the child has achieved an expressive lexicon of 200 words. The templates appear to serve as a kind of ‘holding strategy’, a way for children to produce more complex adult word forms while remaining within the limits imposed by the articulatory, planning, and memory limitations of the early word period. Templates have been identified in the early words of children acquiring a number of languages, although not all children give clear evidence of using them. Within a given language we see a range of different templatic patterns, but these are nevertheless broadly shaped by the prosodic characteristics of the adult language as well as by the idiosyncratic production preferences of a given child; it is thus possible to begin to outline a typology of child templates. However, the evidence base for most languages remains small, ranging from individual diary studies to rare longitudinal studies of as many as 30 children. Thus templates undeniably play a role in phonological development, but their extent of use or generality remains unclear, their timing for the children who show them is unpredictable, and their period of sway is typically brief—a matter of a few weeks or months at most. Finally, the formal status and relationship of child phonological templates to adult grammars has so far received relatively little attention, but the closest parallels may lie in active novel word formation and in the lexicalization of commonly occurring expressions, both of which draw, like child templates, on the mnemonic effects of repetition.
The phonology of Italian is subject to considerable variability both at the segmental and at the prosodic level. Changes affect different features of the phonological system such as the composition of the inventory of phonemes and allophones, the phonotactic patterning of phonemes, and their lexical distribution. On the prosodic level, the variability takes the form of a composite collection of intonational patterns. In fact, the classification of intonational contours in geographical varieties appears fuzzier and less precise than the traditional division into geographical areas based on segmental features.
The reasons for the high variability must be traced back, on the one hand, to the rapid and recent standardization and, on the other hand, to the prolonged contact with Romance dialects of Italy. Variation in Italian phonology can be traced back to two main dimensions: A geographic dimension, accounting for a large proportion of the total variability, and a social dimension that regulates variety-internal variation.
The overall picture can be understood as a combination of vertical and horizontal sociolinguistic forces. Horizontal dynamics is responsible for the creation of a pluricentric standard, that is, a multiplicity of models of pronunciation that could be considered as geographical versions of the standard. Vertical dynamics brings about the formation of new norms at a local level and, most important, it generates a continuum of dialects ranging from the (regional) standard to the most local variety. Moving along this vertical continuum from the standard down to the local variety, there is an increasing of variability that represents a source for the emergence of social and stylistic values.
Pidgin languages sometimes form in contact situations where a means of communication is urgently needed between groups lacking a common code. They are typically less elaborate than any of the languages involved in their formation, and in comparison to those, reduction characterizes all linguistic levels.
The process is relatively uncommon, and the life span of pidgins is usually short – most disappear when the contact situation changes, or when another medium of intergroup communication becomes available. In some rare cases, however, they expand (both socially and structurally), and may even nativize, i. e. become mother tongues to their speakers (when they may be re-labelled “creoles”).
Pidgins are severely understudied, and while they are often mentioned as precursors to creoles, few linguists have shown a serious interest in them. As a result, many generalizations have been based on extremely limited amounts of data or even on intuition. Some frequently occurring ones is that pidginization is a case of second language acquisition, that power and prestige are important factors, and that most structures are derived from the input languages. My work with pidgins has led me to believe the opposite to be true in these cases: pidgins form through a trial-and-error process, where anything that is understood by the other party is sanctioned, this process is one of collaborative language creation (rather than one involving one group of teachers and one group of learners), and much of what finds its way in the resultant contact language do so independently of what the creators spoke prior to their encounter.
As for theoretical implications, pidgins may shed light on which features in traditional languages are necessary for communication, and which are superfluous from the point of view of pure information transmission.
