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.
