Weak interest in the weaker language

Carroll's paper (Carroll) is most welcomed and shows that the weaker language is still to be explored from various points of views. Over twenty years after the publication of Schlyter's paper, “The weaker language in bilingual Swedish-French children”, not only is the topic of the weaker language of simultaneous bilinguals still a clearly under-researched area, but it is also, as Carroll shows, a crucial domain of research in the discussion of properties and constraints of the human Language Making Capacity (LMC).
