title: Language Combinations, Subtypes, and Severity in the Study of Bilingual Children with Specific Language Impairment.
abstract: I commend Johanne Paradis not only for her interesting keynote article but also for the careful research that she has conducted along with her collaborators in the area of bilingual language development and disorders. Her contributions have been significant and are sure to shape our theoretical as well as clinical understanding of specific language impairment (SLI). In this commentary, I focus on three issues. The first stems quite directly from ideas raised in the keynote article; the second and third deal with factors that we need to consider when conducting research involving comparison groups of bilingual and monolingual children with SLI.
