Morphosyntax Constructions of the World's Languages

Many types of event do not conform to the exemplar for transitivity -- namely, an agentive change of state event -- or the prototype of an argument structure construction, expressing an event with an acyclic (linear) causal chain. Reciprocal and reflexive events involve participants both acting on and being acted upon. Constructions for such events tend to recruit the prototypical transitive construction and evolve to an intransitive construction. Less prototypical bivalent events include motion, contact, and application/removal events. These events vary as to which non-agent participant is construed as core, and can be ranked on a hierarchy of transitivity. Experiential events involve an experiencer attending to a stimulus which in turn affects the experiencer; arguments of experiential events are expressed highly variably across languages. Ditransitive constructions are defined by the exemplar of the transfer event of giving. Ditransitive constructions differ as to the alignment of their nonsubject argument phrases with respect to the transitive construction, including the not infrequent neutral strategy in which both theme and recipient are encoded like transitive objects.
