I’ve recently been giving a lot of thought to ‘acquisition’ versus ‘learning’ of a second (or subsequent) language. In brief, the difference is related to communicative competence versus “explicit rule-based grammar teaching” (Lightbown & Spada, 2013, p. 193). (For more on the distinction, click here). In my mind, acquisition is perhaps the longer-lasting state or the point at which conscious rule-based practice becomes automatic communication, as in Skill Acquisition Theory.
