Cognate object


In linguistics, a cognate object is a verb's object that is etymologically related to the verb. More specifically, the verb is one that is ordinarily intransitive, and the cognate object is simply the verb's noun form. This verb also has a passive form.For example, in the sentence He slept a troubled sleep, sleep is the cognate object of the verb slept.And the passive is A troubled sleep was slept by him.

Examples

In English, the construction can occur with a number of intransitive verbs, which then become transitive:
In some of these cases, the cognate object allows for a simpler construction. In others, it may be chosen for idiomatic or rhetorical reasons. In general, the cognate object's modifiers are in some sense modifying the verb: for example, He slept a troubled sleep tells how he slept. Semantically, many of these verbs denote modes of nonverbal expression and bodily actions or motions, specifically including what Levin calls "waltz verbs," those that are zero-related to the names of dances.
