An extension of the sense of one word narrows the meaning of neighboring words, with the words in a field fitting neatly together like a mosaic. If a single word undergoes a semantic change, then the whole structure of the lexical field changes. The lexical field is often used in English to describe terms further with use of different words.
In systemic-functional linguistics, a lexis or lexical item is the way one calls a particular thing or a type of phenomenon. Since a lexis from a systemic-functional perspective is a way of calling, it can be realised by multiple grammatical words such as "The White House", "New York City" or "heart attack".
The origin of the field theory of semantics is the lexical field theory introduced by Jost Trier in the 1930s, [10]: 31 although according to John Lyons it has historical roots in the ideas of Wilhelm von Humboldt and Johann Gottfried Herder. [1] In the 1960s Stephen Ullmann saw semantic fields as crystallising and perpetuating the values of ...
Lexical semantics (also known as lexicosemantics), as a subfield of linguistic semantics, is the study of word meanings. [1] [2] It includes the study of how words structure their meaning, how they act in grammar and compositionality, [1] and the relationships between the distinct senses and uses of a word.
Studies beyond the analysis of single words have been started with the word-field analyses of Trier (1931), who claimed that every semantic change of a word would also affect all other words in a lexical field. [5] His approach was later refined by Coseriu (1964). Fritz (1974) introduced Generative semantics.
A straightforward method of introducing new terms in a language is to create a neologism, i.e. a completely new lexical item in the lexicon.For example, in the philosopher Heidegger's native German, he introduced neologisms to describe various concepts in his ontology (Dasein and Mitsein, for instance; both derived from common German words da and sein, etc.).
To facilitate the interoperability between lexical resources, linguistic annotations and annotation tools and for the systematic handling of linguistic categories across different theoretical frameworks, a number of inventories of linguistic categories have been developed and are being used, with examples as given below.
Lexical meaning is not limited to a single form of a word, but rather what the word denotes as a base word. For example, the verb to walk can become walks , walked , and walking – each word has a different grammatical meaning, but the same lexical meaning ("to move one's feet at a regular pace").
