This document discusses learner strategies in second language acquisition. It defines declarative and procedural knowledge, as well as learning strategies like memorization and inferencing. Formulaic speech involves memorized chunks of language that are used in particular contexts. Creative speech involves novel sentence production using the learner's internalized rules. Hypothesis formation and testing allow learners to develop and experiment with rules of the second language. Planning and production strategies help learners organize and articulate their language. Communication strategies help bridge gaps between the learner's language ability and that of their interlocutor.
