In linguistics, the study of quantity is concerned with the behavior of expressions that refer to amounts in terms of the internal structure of objects and events, their spatial or temporal extension (as duration and boundedness), their qualifying properties, as well as how these aspects interact with each other and other linguistic phenomena. Quantity is primarily manifest in language for the lexical categories of noun, verb, and adjective/ adverb. For instance, the distinction between mass and count nouns is essentially quantitative: it indicates how nominal denotation is quantized—as substance (e.g., water, sand) or as an atomic individual (e.g., book, boy). Similarly, the aspectual classes of verbs, such as states (know), activities (run), accomplishments (drown), achievements (notice), and semelfactives (knock) represent quantitatively different types of events. Adjectives and adverbs may lexically express quantities in relation to individuals, respectively, events (e.g., little, enough, much, often), and one might argue that numerals (two, twenty) are intrinsic quantitative expressions. Quantitative derivation refers to the use of derivational affixes to encode quantity in language. For instance, the English suffix -ful attaches to a noun N1 to derive another noun N2, such that N2 denotes the quantity that fits in the container denoted by N1. N2 also employs a special use in quantitative constructions: see hand—a handful of berries. The challenge for the linguistic description of quantity is that it often combines with other linguistic notions such as evaluation, intensification, quality, and it does not have a specific unitary realization—it is usually auxiliary on other more established notions. Quantitative affixes either have limited productivity or their primary use is for other semantic notions. For instance, the German suffix ‑schaft typically forms abstract nouns as in Vaterschaft ‘fatherhood’, but has a (quantity-related) collective meaning in Lehrerschaft ‘lecturer staff’; compare English -hood in childhood and the collective neighborhood. This diversity makes quantity difficult to capture systematically, in spite of its pervasiveness as a semantic notion.
The words and word-parts children acquire at different stages offer insights into how the mental lexicon might be organized. Children first identify ‘words,’ recurring sequences of sounds, in the speech stream, attach some meaning to them, and, later, analyze such words further into parts, namely stems and affixes. These are the elements they store in memory in order to recognize them on subsequent occasions. They also serve as target models when children try to produce those words themselves. When they coin words, they make use of bare stems, combine certain stems with each other, and sometimes add affixes as well. The options they choose depend on how much they need to add to coin a new word, which familiar elements they can draw on, and how productive that option is in the language. Children’s uses of stems and affixes in coining new words also reveal that they must be relying on one representation in comprehension and a different representation in production. For comprehension, they need to store information about the acoustic properties of a word, taking into account different occasions, different speakers, and different dialects, not to mention second-language speakers. For production, they need to work out which articulatory plan to follow in order to reproduce the target word. And they take time to get their production of a word aligned with the representation they have stored for comprehension. In fact, there is a general asymmetry here, with comprehension being ahead of production for children, and also being far more extensive than production, for both children and adults. Finally, as children add more words to their repertoires, they organize and reorganize their vocabulary into semantic domains. In doing this, they make use of pragmatic directions from adults that help them link related words through a variety of semantic relations.
The onomasiological approach is a theoretical framework that emphasizes the cognitive-semantic component of language and the primacy of extra-linguistic 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, especially 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 models adhering to such a view of language have earned a pivotal position as an alternative to dominant theories of word-formation.

Affixation is the morphological process that consists of adding an affix (i.e., a bound morpheme) to a morphological base. It is cross-linguistically the most common process that human languages use to derive new lexemes (derivational affixation) or to adapt a word’s form to its morphosyntactic context (inflectional affixation). Suffixes (i.e., bound morphemes following the base) and prefixes (i.e., bound morphemes preceding the base) are the most common affixes, with suffixation being more frequently recorded in the world’s languages than prefixation. Minor types of affixation include circumfixation and infixation. Conversion and back-formation are related derivational processes that do not make use of affixation. Many studies have concentrated on the need to differentiate derivation from inflection, but these morphological processes are probably best described as two end points of a cline. Prototypically, derivation is used to change a word’s category (part of speech) and involves a semantic change. A word’s inflectional distinctions make up its paradigm, which amounts to the different morphological forms that correlate with different morphosyntactic functions. Form-function mapping in (derivational and inflectional) affixation is a key issue in current research on affixation. Many deviations from the canonical One Form-One Meaning principle can be observed in the field of affixation. From a diachronic point of view, it has been demonstrated that affixes often derive from free lexemes by grammaticalization, with affixoids being recognized as an intermediate step on this cline. More controversial, but still attested, is the opposite change whereby affixes and affixoids develop into free morphemes through a process of degrammaticalization.
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.
Due to the agglutinative character, Japanese and Ryukyuan morphology is predominantly concatenative, applying to garden-variety word formation processes such as compounding, prefixation, suffixation, and inflection, though nonconcatenative morphology like clipping, blending, and reduplication is also available and sometimes interacts with concatenative word formation. The formal simplicity of the principal morphological devices is counterbalanced by their complex interaction with syntax and semantics as well as by the intricate interactions of four lexical strata (native, Sino-Japanese, foreign, and mimetic) with particular morphological processes. A wealth of phenomena is adduced that pertain to central issues in theories of morphology, such as the demarcation between words and phrases; the feasibility of the lexical integrity principle; the controversy over lexicalism and syntacticism; the distinction of morpheme-based and word-based morphology; the effects of the stage-level vs. individual-level distinction on the applicability of morphological rules; the interface of morphology, syntax, and semantics, and pragmatics; and the role of conjugation and inflection in predicate agglutination. In particular, the formation of compound and complex verbs/adjectives takes place in both lexical and syntactic structures, and the compound and complex predicates thus formed are further followed in syntax by suffixal predicates representing grammatical categories like causative, passive, negation, and politeness as well as inflections of tense and mood to form a long chain of predicate complexes. In addition, an array of morphological objects—bound root, word, clitic, nonindependent word or fuzoku-go, and (for Japanese) word plus—participate productively in word formation. The close association of morphology and syntax in Japonic languages thus demonstrates that morphological processes are spread over lexical and syntactic structures, whereas words are equipped with the distinct property of morphological integrity, which distinguishes them from syntactic phrases.
