This study examines the acquisition of the linguistic mass/count distinction in English by bilingual (Spanish-English) children. The goal of the study is to explore whether bilingual children, like their monolingual peers, can draw information from the linguistic context in which a new noun id presented to determine whether the new word refers to an object or a substance. Results indicate that at 7 years of age, even bilinguals who are strong in English do not yet draw such inferences. By 9 years of age, however, bilinguals who are strong in English have response patterns similar to those of their monolingual peers but bilinguals who have lower English abilities still lag behind their monolingual peers in drawing such inferences.
