While already three-year-old German-speaking children produce transitive sentences in the non-canonical OVS word order, even seven-year-olds have problems understanding OVS sentences. Previous research showed that topic-first contexts ease OVS processing in adults and personal pronouns ease the comprehension of object relative clauses in preschoolers. This may be explained by a reduction of intervention effects or processing costs or by providing a cue to the subject status. We investigated the impact of context and type of referring expression on OVS sentence comprehension in German-speaking four-year-olds, five-year-olds, and seven-year-olds. Our data show that a topic-first context (compared to a neutral context) did not ease OVS comprehension when both arguments were realized as lexical NPs. However, realizing the topic as personal pronoun eased comprehension in topic-first (pronoun=object) and topic-last (pronoun=subject) contexts. This indicates that personal pronouns may reduce intervention effects or processing costs. Five-year-olds showed higher OVS comprehension accuracy in topic-last contexts. They may be influenced by the frequency-based link between personal pronouns, topic status, and word order.
