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 ...
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.
A word can have two kinds of meaning: grammatical and lexical. Grammatical meaning refers to a word's function in a language, such as tense or plurality, which can be deduced from affixes. Lexical meaning is not limited to a single form of a word, but rather what the word denotes as a base word.
The words in a lexicon (the set of words used in some language) have a conventional ordering, used in dictionaries and encyclopedias, that depends on the underlying ordering of the alphabet of symbols used to build the words. The lexicographical order is one way of formalizing word order given the order of the underlying symbols.
Lexical aspect, a characteristic of the meaning of verbs; Lexical form, the canonical form of a word, under which it appears in dictionaries; Lexical definition or dictionary definition, the meaning of a term in common usage; Lexical semantics, a subfield of linguistic semantics that studies how and what the words of a language denote
[2] [3] The root word is the primary lexical unit of a word, and of a word family (this root is then called the base word), which carries aspects of semantic content and cannot be reduced into smaller constituents. Content words in nearly all languages contain, and may consist only of, root morphemes.
Surface forms of words are those found in natural language text. The corresponding lexical form of a surface form is the lemma followed by grammatical information (for example the part of speech, gender and number). In English give, gives, giving, gave and given are surface forms of the verb give. The lexical form would be "give", verb.
A major area of study, psycholinguistics and neurolinguistics, involves the question of how words are retrieved from the mental lexical corpus in online language processing and production. For example, the cohort model seeks to describe lexical retrieval in terms of segment-by-segment activation of competing lexical entries. [3] [4]
