The study aimed to explore cross-linguistic contributions of morphological awareness to Chinese reading acquisition among Chinese heritage language (CHL) learners who had grown up speaking Chinese at home, received English medium education throughout schooling, and were studying Chinese at the time of the study. The sample thus represents a growing number of heritage-language (HL) speakers in US schools whose literacy development is not yet well documented. Little is known, to date, as to how HL literacy development benefits from the linguistic and metalinguistic resources gained through early oral language exposure. In the study, college-level CHL students (N = 195) completed a series of reading measures in their dominant language (English) and heritage language (Chinese). Path analysis was employed to test the cross-linguistic relationships in morphological awareness and lexical inference ability. The findings showed that dominant-language morphological awareness was significantly related to lexical inference skills in two languages. More critically, the current study tested the direct and indirect contributions of dominant-language morphological awareness to HL lexical inference. The results showed that dominant-language morphological awareness contributed only indirectly to HL lexical inference through HL morphological awareness and dominant-language lexical inference. Based on the findings, four tentative conclusions can be drawn: morphological awareness and lexical inference skills transfer across languages; cross-linguistic interaction only occurs between corresponding subskills; transferred subskills are modified to accommodate the target language properties; and the benefits of transferred subskills are realized only through their corresponding subskills in the target language. Practical implications of the findings are also discussed regarding HL instruction and learning.
