The lexical definition of a term, also known as the dictionary definition, is the definition closely matching the meaning of the term in common usage. As its other name implies, this is the sort of definition one is likely to find in the dictionary. A lexical definition is usually the type expected from a request for definition, and it is ...

The verb phrase of a sentence is generally headed by a lexical verb. [1] Lexical verbs are categorized into five categories: copular, intransitive, transitive, ditransitive, and ambitransitive. [2] [3] The descriptor lexical is applied to the words of a language's lexicon, often to indicate a content word, as distinct from a function word. [4]
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. [2]
In lexicography [citation needed], a lexical item is a single word, a part of a word, or a chain of words that forms the basic elements of a language's lexicon (≈ vocabulary). [ citation needed ] Examples are cat , traffic light , take care of , by the way , and it's raining cats and dogs .

[ 1 ] Linguistic theories generally regard human languages as consisting of two parts: a lexicon, essentially a catalogue of a language's words (its wordstock); and a grammar , a system of rules which allow for the ...
For example, a typical lexical analyzer recognizes parentheses as tokens but does nothing to ensure that each "(" is matched with a ")". When a lexer feeds tokens to the parser, the representation used is typically an enumerated type, which is a list of number representations. For example, "Identifier" can be represented with 0, "Assignment ...
