On the acquisition of event culmination

There is quite a high rate of acceptance of telic-perfective predicates as descriptions of non-culminating events in children learning Germanic and Romance languages. What causes children, much more so than adults, to accept non-culminating interpretations of telic-perfective sentences? In this review, I discuss learners’ difficulties in each of three grammatical dimensions that contribute to event culmination: the notion of ‘result’ as encoded in the lexical semantics of verbs, telicity of verb phrases, and perfectivity of tense-aspect morphology. I conclude that telicity and perfectivity do not cause the non-culmination acceptance patterns. Instead, the learnability challenge for event culmination lies in the acquisition of verb meanings. I sketch several new angles for further research, including the role of agentivity of the subject.
