Acquisition of English relative clauses by native speakers of Kurdish Sorani

The present study investigates several linguistic factors that might be determinants of differences in the ease of acquisition of relative clauses (RCs) in L2 contexts, using the acquisition of English relative clauses by Kurdish Sorani native speakers. The analysis of 1440 subject and object RCs formed by Kurdish Sorani-speaking learners of English in a sentence combination task and a sentence translation task indicates that the syntactic functions of the noun phrase (NP) relativized in the RC, the position of the RC in the matrix clause (whether centre- or right-embedded), and the properties of RCs in L1 affect the acquisition and the formation of RCs in L2. The study also provides evidence that the syntactic functions of the relativized NP in the matrix clause, and the consistency/inconsistency of word orders in L1 and L2 do not influence the acquisition of RCs in L2.
