Lexeme
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 . One form, the lemma (or citation form), is chosen by convention as the canonical form of a lexeme. The lemma is the form used in dictionaries as an entry's headword. Other forms of a lexeme are often listed later in the entry if they are uncommon or irregularly inflected. Description The notion of the lexeme is central to morphology, the basis for defining other concepts in that field. For example, the difference between inflection and derivation can be stated in terms of lexemes: * Inflectional rules relate a lexeme to its forms. * Derivational rules relate a lexeme to anothe ...

Morphology (linguistics)
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. While words, along with clitics, are generally accepted as being the smallest units of syntax, in most languages, if not all, many words can be related to other words by rules that collectively describe the grammar for that language. For example, English speakers recognize that the words ''dog'' and ''dogs'' are closely related, differentiated only by the plurality morpheme "-s", only found bound to ...

Word
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. The concept of "word" is distinguished from that of a morpheme, which is the smallest unit of language that has a meaning, even if it cannot stand on its own. Words are made out of at least on ...

Lemma (morphology)
In morphology and lexicography, a lemma (plural ''lemmas'' or ''lemmata'') 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. Morphology The form of a word that is chosen to serve as the lemma is usually the least marked form, but there are several exceptions s ...

Lexical Semantics
Lexical semantics (also known as lexicosemantics), as a subfield of linguistics, linguistic semantics, is the study of word meanings.Pustejovsky, J. (2005) Lexical Semantics: Overview' in Encyclopedia of Language and Linguistics, second edition, Volumes 1-14Taylor, J. (2017) Lexical Semantics'. In B. Dancygier (Ed.), The Cambridge Handbook of Cognitive Linguistics (Cambridge Handbooks in Language and Linguistics, pp. 246-261). Cambridge: Cambridge University Press. It includes the study of how words structure their meaning, how they act in grammar and Principle of compositionality, compositionality, and the relationships between the distinct senses and uses of a word. The units of analysis in lexical semantics are lexical units which include not only words but also sub-words or sub-units such as affixes and even compound words and phrases. Lexical units include the catalogue of words in a language, the lexicon. Lexical semantics looks at how the meaning of the lexical units correl ...

Inflection
In linguistic morphology, inflection (or inflexion) 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''. An inflection expresses grammatical categories with affixation (such as prefix, suffix, infix, circumfix, and transfix), apophony (as Indo-European ablaut), or other modifications. For example, the Latin verb ', meaning "I will lead", includes the suffix ', expressing person (first), number (singular), and tense-mood (future indicative or present subjunctive). The use of this suffix is an inflection. In contrast, in the English clause "I will lead", the word ''lead'' is not inflected for ...

Morphological Derivation
Morphological derivation, in linguistics, is the process of forming a new word from an existing word, often by adding a prefix or suffix, such as For example, ''unhappy'' and ''happiness'' derive from the root word ''happy.'' It is differentiated from inflection, which is the modification of a word to form different grammatical categories without changing its core meaning: ''determines'', ''determining'', and ''determined'' are from the root ''determine''. Derivational patterns Derivational morphology often involves the addition of a derivational suffix or other affix. Such an affix usually applies to words of one lexical category (part of speech) and changes them into words of another such category. For example, one effect of the English derivational suffix ''-ly'' is to change an adjective into an adverb (''slow'' → ''slowly''). Here are examples of English derivational patterns and their suffixes: * adjective-to-noun: ''-ness'' (''slow'' → ''slowness'') * adjective ...

Language
Language is a structured system of communication. The structure of a language is its grammar and the free components are its vocabulary. Languages are the primary means by which humans communicate, and may be conveyed through a variety of methods, including spoken, sign, and written language. Many languages, including the most widely-spoken ones, have writing systems that enable sounds or signs to be recorded for later reactivation. Human language is highly variable between cultures and across time. Human languages have the properties of productivity and displacement, and rely on social convention and learning. Estimates of the number of human languages in the world vary between and . Precise estimates depend on an arbitrary distinction (dichotomy) established between languages and dialects. Natural languages are spoken, signed, or both; however, any language can be encoded into secondary media using auditory, visual, or tactile stimuli – for example, writing ...

Morpheme
A morpheme is the smallest meaningful constituent of a linguistic expression. The field of linguistic study dedicated to morphemes is called morphology. In English, morphemes are often but not necessarily words. Morphemes that stand alone are considered roots (such as the morpheme ''cat''); other morphemes, called affixes, are found only in combination with other morphemes. For example, the ''-s'' in ''cats'' indicates the concept of plurality but is always bound to another concept to indicate a specific kind of plurality. This distinction is not universal and does not apply to, for example, Latin, in which many roots cannot stand alone. For instance, the Latin root ''reg-'' (‘king’) must always be suffixed with a case marker: ''rex'' (''reg-s''), ''reg-is'', ''reg-i'', etc. For a language like Latin, a root can be defined as the main lexical morpheme of a word. These sample English words have the following morphological analyses: * "Unbreakable" is composed of three ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emic Unit
In linguistics and related fields, an emic unit is a type of abstract object. cited in Kinds of emic units are generally denoted by terms with the suffix ''-eme'', such as ''phoneme'', ''grapheme'', and ''morpheme''. The term "emic unit" is defined by Nöth (1995) to mean "an invariant form obtained from the reduction of a class of variant forms to a limited number of abstract units". The variant forms are called etic units (from ''phonetic''). This means that a given emic unit is considered to be a single underlying object that may have a number of different observable "surface" representations. The various etic units that represent a given emic unit of a certain kind are denoted by a corresponding term with the prefix ''allo-'', such as ''allophone'', ''allograph'', and ''allomorph''. History and terminology The first emic unit to be considered, in the late 19th century, was the phoneme. The word ''phoneme'' comes from the el, φώνημα, , meaning "that which is sounded", ...
