6. (grammar) Deviation from standard word order, as for example by putting the predicate before the subject. It takes place in questions with auxiliary verbs; in normal, affirmative clauses beginning with a negative particle, for the purpose of emphasis; and in other rhetorical devices or unusual situations.Examples: "Inversion takes place in the sentence 'Is she here?' — 'is', the predicate, is before 'she', the subject."; "Inversion takes place in the sentence 'Never have I done that.' — 'have', the predicate, is before 'I', the subject, due to 'never' being the first word of the sentence."; "Question formation involves the phenomenon commonly known as subject-auxiliary inversion, a change in word order in which the auxiliary moves in front of the subject. (a) Here we shall describe this phenomenon in terms of movement of the element under INFL into COMP position. (b) According to this analysis, what looks like an exchanging of positions between the subject and auxiliary (or INFL element, in GB terms) is actually the movement of the INFL element past the subject position into COMP. (c) INFL-to-COMP movement seems to be triggered by the presence of the [+WH] feature in COMP."Synonyms: anastrophe#Noun, hyperbatoncountableuncountable
