By replicating Cho (2017), this article investigates how second language (L2) learners with an article-less first language acquire two types of English definiteness, anaphoric and nonanaphoric. Mandarin Chinese, as an article-less language, has a demonstrative determiner that shares the same feature set as the English definite article "the": [+definite, +/-anaphoric]. In the current study, the participants were 28 advanced and 25 intermediate L1-Chinese L2-English learners and the native control data were from Cho. The results from an acceptability judgment task revealed that intermediate Chinese speakers, unlike advanced speakers, had difficulties in the nonanaphoric definite condition where, without a potential antecedent, definiteness is established through pragmatic knowledge and acquisition of nonanaphoric definiteness essentially takes place at the semantics-pragmatics interface. The findings of this article suggest that accommodating presuppositions at the semantics-pragmatics interface is challenging to L2 learners, even when feature reassembly is not required.
