The serial verb construction, also known as (verb) serialization or verb stacking, is a syntactic phenomenon in which two or more verbs or verb phrases are strung together in a single clause. It is a common feature of many African, Asian and New Guinean languages. Serial verb constructions are often described as coding a single event; they can also be used to indicate concurrent or causally-related events.
The terms "serial verbs", "serialization", etc. are used by different authors to denote somewhat different sets of constructions. There are also differences in how the constructions are analyzed, in terms of both syntax and semantics.
In general, a structure described as a serial verb construction will consist either of two (or possibly more) consecutive verbs or of two or more consecutive verb phrases in which each verb may have its own object and possibly other modifiers. There will usually be no marking, by means of affixes or subordinating conjunctions, that one verb is dependent on the other, and they will not be linked by coordinating conjunctions. Some linguists insist that serial verbs cannot be dependent on each other; however, if a language does not mark dependent verbs with affixation, it can be hard to determine whether any dependency relation exists when verbs appear in sequence.
Serial verbs normally denote actions that are closely connected and can be considered to be part of the same event. They may be actions taking place simultaneously, or one may represent the cause, purpose or result of the other. In most cases, the serial verbs in a sequence are understood to share the same subject.
Certain expressions resembling serial verb construction are found in English (surviving from Early Modern English), such as let's go eat and come live with me. In such constructions, the second verb would normally be regarded as a bare infinitive (and can generally be replaced by a "full" infinitive by the insertion of to before it).
