- An auxiliary verb is a verb that adds functional or grammatical meaning to the clause in which it appears — for example, to express tense, aspect, modality, voice, emphasis, etc. Auxiliary verbs usually accompany a main verb. The main verb provides the main semantic content of the clause.  An example is the verb have in the sentence I have finished my dinner. Here, the main verb is finish, and the auxiliary have helps to express the perfect aspect. Some sentences contain a chain of two or more auxiliary verbs. Auxiliary verbs are also called helping verbs, helper verbs, or (verbal) auxiliaries. They may be glossed with the abbreviation AUX.

- QUOTE: lexis (n.) A term used in LINGUISTIC to refer to the vocabulary of a LANGUAGE … A UNIT of vocabulary is generally referred to as a lexical item, or LEXEME. A complete inventory of the lexical items of a language constitutes that language's dictionary, or LEXICON … 'in the lexicon' as a set of lexical entries. … … Lexis may be seen in contrast with GRAMMAR, as in the distinction between grammatical WORDS and lexical words: the former refers to words whose sole function is to signal grammatical relationships (a role which is claimed for such words as of, to and the in English); the latter refers to words which have lexical meaning, i.e. they have semantic CONTENT. Examples include lexical verbs (versus auxiliary verbs) and lexical noun phrases (versus non-lexical NPs, such as PRO). A similar contrast distinguishes lexical morphology from derivational MORPHOLOGY.
