10 - Intergenerational Transmission

Summary

This chapter presents a more fine-grained analysis of why and how DOM vulnerability may have become more prevalent in Spanish than in Hindi and Romanian at the individual level. Specifically, linking language acquisition, language attrition and diachronic language change, it addresses the question of the potential relationship between the I-language of the heritage speakers and the E-language of the first-generation immigrants, who are often the heritage speakers’ main source of input. It presents follow-up studies of DOM in Spanish-speaking bilingual children and adults and their mothers and the results are not consistent with direct transmission of DOM omission from the first to the second-generation (the heritage speakers). It is suggested that that second-generation heritage speakers, who have as much difficulty mastering the morphology of their heritage language as typical L2 learners, can also change the grammars of the parental generation and be the innovators in the Spanish variety spoken in the United States.
