Masha on understanding heritage languages

Bilingualism features a new keynote article from Maria Polinsky and Gregory Scontras on Understanding heritage languages. The paper aims to "synthesize pertinent empirical observations and theoretical claims about vulnerable and robust areas of heritage language competence into early steps toward a model of heritage-language grammar[, ...] highlighting two key triggers for deviation from the relevant baseline: the quantity and quality of the input from which the heritage grammar is acquired, and the economy of online resources when operating in a less dominant language.''
