" Language acquisition" refers to the subconscious process leading to the development of "competence" and is not dependent on the .teaching of grammatical rules. "Language learning" refers to the conscious study and knowledge of grammatical rules. Acquisition takes place during real communication in the language and is considered to be the source of the students’ ability to use the language. Learning may contribute to the self-monitoring, or self-editing, of language output that sometimes occurs when speakers have time to reflect and focus on the form of their utterances.
