Serial verbs

In terms of their composition, serial verb constructions divide into asymmetrical and symmetrical. Asymmetrical serial verbs consist of a minor component from a closed class of verbs, and a major component from an open class; this is the head of the construction. Symmetrical serial verbs consist of several components from open classes. Asymmetrical serial verb constructions cover a wide array of meanings—direction and orientation, aspect, extent and change of state, associated posture and motion, increasing and reducing valency, and marking the index of comparison. They are also used as complementation strategies with secondary concept verbs and with complement-taking verbs, and mark manner modification in event-argument constructions. The recurrent meanings of symmetrical serial verbs cover cause-effect, result, and manner, in addition to synonymous verb constructions. The established properties of asymmetrical and symmetrical serial verbs are defined in terms of their meanings, iconicity, internal structure, and grammaticalization and lexicalization.
