The many facets of serial verbs

A single language can have more than one kind of serial verb construction. Serial verbs may differ along the parameters of wordhood and contiguity. Different types of serial verbs may differ in their meanings and the degree of their grammaticalization or lexicalization. The closer the components are in surface structure, the more likely they are to grammaticalize or to lexicalize, and the more restrictions they will display. We expect single-word serial verbs to be more cohesive in their semantics than multi-word serial verbs, in accordance with the principle of iconic motivation. Semantic groups of verbs which are likely to occur in serial verb constructions form a hierarchy, with verbs of direction and motion being most likely, and stative verbs the least likely to occur. If a language has serial verb constructions, we expect directional serial verbs to develop before any other type. All the languages with symmetrical serial verbs also have asymmetrical ones.
