Vulnerability and Cross-linguistic Influence in Heritage Spanish: Comparing Different Majority Languages

Abstract

This paper compares Dutch-dominant and English-dominant heritage speakers of Spanish regarding their sensitivity to the various factors that play a role in subject position. An acceptability judgment task and an elicited production task demonstrated that both groups were sensitive to the effect of verb type on word order, but not to the effect of focus. To account for the specific vulnerability of focus, several possible accounts are proposed. An interesting difference occurred between the two heritage speaker groups regarding their knowledge of the effect of definiteness on word order. The Dutch-dominant group outperformed the English dominant group in this condition, arguably helped by the similarity between Dutch and Spanish regarding the definiteness effect on word order. This finding shows that properties inherent to the heritage language and cross-linguistic influence from the majority language are both crucial elements in explaining vulnerability in heritage grammars.
