Findings from a longitudinal study of bilingual children acquiring
Cantonese and English pose a challenge to the noun phrase accessibility
hierarchy (NPAH; Keenan & Comrie, 1977),
which predicts that object relatives should not be acquired before subject
relatives. In the children's Cantonese, object relatives emerged
earlier than or simultaneously with subject relatives, and in their
English, prenominal relatives based on Cantonese emerged first, with
object relatives followed by subject relatives. These findings are
discussed in light of findings on the typology and acquisition of relative
clauses (RCs) and the underlying processing motivations of the NPAH.
Prenominal object relatives in the bilingual children's Cantonese and
English have the same word order as main clauses and can be analyzed as
internally headed RCs. The reconceptualization of RCs as attributive
clauses (Comrie, 1998a, 1998b, 2002) is supported by
children's early RCs lacking a strict grammatical relationship
between the head noun and the predicate. Furthermore, as observed by
Diessel and Tomasello (2000, 2005) for English, bilingual children's earliest
RCs consist of isolated noun phrases (NPs). The early object relatives
produced by bilingual children are therefore essentially NPs with the
linear order of a main clause, resulting in a configuration that is
conducive to early production.We thank

of RCs at Cornell University in January 2006, where this paper was

this paper. We thank all the participants at the workshop and two
anonymous SSLA reviewers for their comments. Additional feedback
