Lexical semantics in the context of "Meaning (linguistics)"

Choronym (from Greek: χώρα 'region' or 'country' and Greek: ὄνομα 'name') is a linguistic term that designates a proper name of an individual region or a country. The study of regional and country names is known as choronymy, or choronymics. Since choronyms are a subclass of toponyms, choronymic studies represent a distinctive subfield of toponymic studies and belong to the wider field of onomastic studies.

Choronymic studies are primarily focused on questions related to the origin (etymology) and meanings (semantics) of choronyms. Since names of regions and countries have great historical, cultural, political and social significance, the field of choronymic studies is closely related to sociolinguistic and ethnolinguistic studies.

In lexical semantics, opposites are words lying in an inherently incompatible binary relationship. For example, something that is even entails that it is not odd. It is referred to as a 'binary' relationship because there are two members in a set of opposites. The relationship between opposites is known as opposition. A member of a pair of opposites can generally be determined by the question: "What is the opposite of X?"

The term antonym (and the related antonymy) is commonly taken to be synonymous with opposite, but antonym also has other more restricted meanings. Graded (or gradable) antonyms are word pairs whose meanings are opposite and which lie on a continuous spectrum (hot, cold). Complementary antonyms are word pairs whose meanings are opposite but whose meanings do not lie on a continuous spectrum (push, pull). Relational antonyms are word pairs where opposite makes sense only in the context of the relationship between the two meanings (teacher, pupil). These more restricted meanings may not apply in all scholarly contexts, with Lyons (1968, 1977) defining antonym to mean gradable antonyms, and Crystal (2003) warning that antonymy and antonym should be regarded with care.

Conceptual semantics is a framework for semantic analysis developed mainly by Ray Jackendoff in 1976. Its aim is to provide a characterization of the conceptual elements by which a person understands words and sentences, and thus to provide an explanatory semantic representation (title of a Jackendoff 1976 paper). Explanatory in this sense refers to the ability of a given linguistic theory to describe how a component of language is acquired by a child (as proposed by Noam Chomsky; see Levels of adequacy).

Recently, conceptual semantics in particular, and lexical semantics in general, have taken on increasing importance in linguistics and psycholinguistics. Many contemporary theories of syntax (how sentences are constructed from individual words) rely on elements that are idiosyncratic to words themselves. As a result, a sound theory accounting for the properties of the meanings of words is required.

Computational semantics is a subfield of computational linguistics. Its goal is to elucidate the cognitive mechanisms supporting the generation and interpretation of meaning in humans. It usually involves the creation of computational models that simulate particular semantic phenomena, and the evaluation of those models against data from human participants. While computational semantics is a scientific field, it has many applications in real-world settings and substantially overlaps with Artificial Intelligence.

Broadly speaking, the discipline can be subdivided into areas that mirror the internal organization of linguistics. For example, lexical semantics and frame semantics have active research communities within computational linguistics. Some popular methodologies are also strongly inspired by traditional linguistics. Most prominently, the area of distributional semantics, which underpins investigations into embeddings and the internals of Large Language Models, has roots in the work of Zellig Harris.

In linguistics, specifically the sub-field of lexical semantics, the concept of lexical innovation includes the use of neologism or new meanings (so-called semantic augmentation) in order to introduce new terms into a language's lexicon. Most commonly, this is found in technical disciplines where new concepts require names, which often takes the form of jargon. For example, in the subjects of sociology or philosophy, there is an increased technicalization in terminology in the English language for different concepts over time. Many novel terms or meanings in a language are created as a result of translation from a source language, in which certain concepts were first introduced (e.g. from Plato's Ancient Greek into Latin or from Kant's German into English).

A lexeme (/ˈlɛksiːm/ ) 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 the English language, run, runs, ran and running are forms of the same lexeme, which can be represented as RUN.

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.
