Light verb

In linguistics, a light verb is a verb that has little semantic content of its own and forms a predicate with some additional expression, which is usually a noun. Common verbs in English that can function as light verbs are do, give, have, make, and take. Other names for light verb include delexical verb,vector verb, explicator verb, thin verb, empty verb and semantically weak verb (a semantically weak verb is not to be confused with a weak verb of the Germanic weak inflection, however). While light verbs are similar to auxiliary verbs regarding their meaning contribution to the clauses in which they appear, light verbs fail the diagnostics that identify auxiliary verbs and are therefore distinct from auxiliaries.

Light verb constructions challenge theories of compositionality because the words that form such constructions do not together qualify as constituents although the word combinations qualify as catenae.

Most light verb constructions in English include a noun and are sometimes called stretched verbs. Some light verb constructions also include a preposition, e.g.

The light verbs are underlined, and the words in bold together constitute the light verb constructions. Each of these constructions is the (primary part of the) main predicate of the sentence. Note that the determiner a is usually NOT part of the light verb construction. We know that it is not part of the light verb construction because it is variable, e.g. I took a long/the first/two/the best nap. The light verb contributes little content to its sentence; the main meaning resides with the noun in bold.

Many light verb constructions are closely similar in meaning to a corresponding full verb, e.g.

Alternative formulations such as these lead to the insight that light verb constructions are predicates just like the corresponding full verb alternatives. There can be, however, nuanced differences in meaning across these alternative formulations. The light verb constructions produce possibilities for modification that are less available with the corresponding full verb alternatives.
