Compound verb

In linguistics, a compound verb or complex predicate is a multi-wordcompound that functions as a single verb. One component of the compound is a light verb or vector, which carries any inflections, indicating tense, mood, or aspect, but provides only fine shades of meaning. The other, "primary", component is a verb or noun which carries most of the semantics of the compound, and determines its arguments. It is usually in either base or [in Verb + Verb compounds] conjunctive participial form.

A compound verb is also called a "complex predicate" because the semantics, as formally modeled by a predicate, is determined by the primary verb, though both verbs appear in the surface form. Whether Noun+Verb (N+V) compounds are considered to be "compound verbs" is a matter of naming convention. Generally, the term complex predicate usually includes N+V compounds, whereas the term compound verb is usually reserved for V+V compounds. However, several authors [especially Iranists] refer to N+V compounds as compound verbs.

Compound verbs are to be distinguished from serial verbs which typically signify a sequence of actions, and in which the verbs are relatively equal in semantic and grammatical weight. They are also to be distinguished from sequences of auxiliary plus main verbs.
