Heritage speakers offer a unique window into how the human brain processes language
In short: Researchers argue that studying heritage speakers—individuals who grow up with a minority language but do not reach native-like fluency—can fundamentally change our understanding of linguistics. By moving away from the traditional focus on monolingual speakers, scientists can better observe how the human language faculty operates under diverse conditions.
Because heritage speakers often don't reach full native-like fluency in their first language, their grammar offers a natural test case for ideas about case, aspect, and other interface phenomena, challenging theories built mainly on monolingual speakers.
This is a theoretical review that draws together existing research rather than reporting new experiments, so it maps out promising questions for the field without presenting new data of its own.
Why it matters: Studying speakers who are bilingual but not fully native-fluent could reshape how linguists test theories about language acquisition.
