 In Hauser et al. (2002) (henceforth HCF) a further pair of contrasting terms is introduced. They draw a distinction quite separate from the competence/performance and ‘I-language’/‘E-language’ distinctions: the “language faculty in the narrow sense” (FLN) is distinguished from the “language faculty in the broad sense” (FLB). According to HCF, FLB “excludes other organism-internal systems that are necessary but not sufficient for language (e.g., memory, respiration, digestion, circulation, etc.)” but includes whatever is involved in language, and FLN is some limited part of FLB (p. 1571) This is all fairly vague, but it is clear that FLN and FLB are both internal rather than external, and individual rather than social.
