What is the difference between acquisition and learning? Illustrate with examples.
Acquisition refers to the gradual and subconscious development of ability in the first language by using it naturally in daily communicative situations. Learning, however, is defined as a conscious process of accumulating knowledge of a second language usually obtained in school settings. It is recognized that children acquire their native language without explicit learning. A second language is more commonly learned but to some degree may also be acquired, depending on the environmental setting and the input received by the L2 learner.
