In linguistics, declension is the changing of the form of a word, generally to express its syntactic function in the sentence, by way of some inflection. Declensions may apply to nouns, pronouns, adjectives, adverbs, and articles to indicate number, case, gender, and a number of other grammatical categories. Meanwhile, the inflectional change of verbs is called conjugation.
In linguistics, conjugation is the creation of derived forms of a verb from its principal parts by inflection. For instance, the verb break can be conjugated to form the words break, breaks, broke, broken and breaking. While English has a relatively simple conjugation, other languages such as French and Arabic or Spanish are more complex, with each verb having dozens of conjugated forms. Some languages such as Georgian and Basque have highly complex conjugation systems with hundreds of possible conjugations for every verb.
A lexicon is the vocabulary of a language or branch of knowledge. In linguistics, a lexicon is a language's inventory of lexemes. The word lexicon derives from Greek word λεξικόν, neuter of λεξικός meaning 'of or for words'.
A lexeme is a unit of lexical meaning that underlies a set of words that are related through inflection. It is a basic abstract unit of meaning, a unit of morphological analysis in linguistics that roughly corresponds to a set of forms taken by a single root word. For example, in English, run, runs, ran and running are forms of the same lexeme, which can be represented as RUN.
A morpheme is the smallest meaningful constituent of a linguistic expression. The field of linguistic study dedicated to morphemes is called morphology.
In linguistics, morphology is the study of words, how they are formed, and their relationship to other words in the same language. It analyzes the structure of words and parts of words such as stems, root words, prefixes, and suffixes. Morphology also looks at parts of speech, intonation and stress, and the ways context can change a word's pronunciation and meaning. Morphology differs from morphological typology, which is the classification of languages based on their use of words, and lexicology, which is the study of words and how they make up a language's vocabulary.
Dyirbal is an Australian Aboriginal language spoken in northeast Queensland by the Dyirbal people. In 2016, the Australian Bureau of Statistics reported that there were 8 speakers of the language. It is a member of the small Dyirbalic branch of the Pama–Nyungan family. It possesses many outstanding features that have made it well known among linguists.
Realizational morphology or "word-and-paradigm" (WP) was a theory first created by linguist, Charles F. Hockett. WP morphology focuses on the whole of a word rather than morphemes or internal structure. This theory also denies that morphemes are signs. Instead, inflections are stem modifications which serve as exponents of morphological feature sets. It serves as an alternative for the Item-and-Arrangement (IA) and Item-and-Process (IP) Models.
In linguistics, a word stem is a part of a word responsible for its lexical meaning. The term is used with slightly different meanings depending on the morphology of the language in question. In Athabaskan linguistics, for example, a verb stem is a root that cannot appear on its own and that carries the tone of the word. Athabaskan verbs typically have two stems in this analysis, each preceded by prefixes.
A word is a basic element of language that carries an objective or practical meaning, can be used on its own, and is uninterruptible. Despite the fact that language speakers often have an intuitive grasp of what a word is, there is no consensus among linguists on its definition and numerous attempts to find specific criteria of the concept remain controversial. Different standards have been proposed, depending on the theoretical background and descriptive context; these do not converge on a single definition. Some specific definitions of the term "word" are employed to convey its different meanings at different levels of description, for example based on phonological, grammatical or orthographic basis. Others suggest that the concept is simply a convention used in everyday situations.
In morphology and lexicography, a lemma is the canonical form, dictionary form, or citation form of a set of word forms. In English, for example, break, breaks, broke, broken and breaking are forms of the same lexeme, with break as the lemma by which they are indexed. Lexeme, in this context, refers to the set of all the inflected or alternating forms in the paradigm of a single word, and lemma refers to the particular form that is chosen by convention to represent the lexeme. Lemmas have special significance in highly inflected languages such as Arabic, Turkish and Russian. The process of determining the lemma for a given lexeme is called lemmatisation. The lemma can be viewed as the chief of the principal parts, although lemmatisation is at least partly arbitrary.
Epistemic modality is a sub-type of linguistic modality that encompasses knowledge, belief, or credence in a proposition. Epistemic modality is exemplified by the English modals may, might, must. However, it occurs cross-linguistically, encoded in a wide variety of lexical items and grammatical structures. Epistemic modality has been studied from many perspectives within linguistics and philosophy. It is one of the most studied phenomena in formal semantics.
In linguistics, word formation is an ambiguous term that can refer to either:
In linguistics, syncretism exists when functionally distinct occurrences of a single lexeme, morph or phone are identical in form. The term arose in historical linguistics, referring to the convergence of morphological forms within inflectional paradigms. In such cases, a former distinction has been 'syncretized'. The term syncretism is often used when a fairly regular pattern can be observed across a paradigm.
In linguistics, periphrasis is the use of one or more function words to express meaning that otherwise may be expressed by attaching an affix or clitic to a word. The resulting phrase includes two or more collocated words instead of one inflected word. The word periphrasis originates from the Greek word periphrazein, which means talking around.
Deflexion is a diachronic linguistic process in inflectional languages typified by the degeneration of the inflectional structure of a language. All members of the Indo-European language family are subject to some degree of deflexional change. This phenomenon has been especially strong in Western European languages, such as English, French, and others.
Meaning–text theory (MTT) is a theoretical linguistic framework, first put forward in Moscow by Aleksandr Žolkovskij and Igor Mel’čuk, for the construction of models of natural language. The theory provides a large and elaborate basis for linguistic description and, due to its formal character, lends itself particularly well to computer applications, including machine translation, phraseology, and lexicography.
In linguistic morphology, inflection is a process of word formation in which a word is modified to express different grammatical categories such as tense, case, voice, aspect, person, number, gender, mood, animacy, and definiteness. The inflection of verbs is called conjugation, and one can refer to the inflection of nouns, adjectives, adverbs, pronouns, determiners, participles, prepositions and postpositions, numerals, articles, etc., as declension.
The term morphome refers to a function in linguistics which is purely morphological or has an irreducibly morphological component. The term is particularly used by Martin Maiden following Mark Aronoff's identification of morphomic functions and the morphomic level—a level of linguistic structure intermediate between and independent of phonology and syntax. In distinguishing this additional level, Aronoff makes the empirical claim that all mappings from the morphosyntactic level to the level of phonological realisation pass through the intermediate morphomic level.
