BACKGROUND TO LANGUAGE LEARNING
(Spratt et al)
Exposure to language means being in contact with language by hearing it or reading it. We can learn another language through exposure to it. We can learn a language without realising we are learning it and without studying it, in the same way that children learn their mother tongue. Learners can get exposure to language outside the classroom by watching movies in English and reading books or magazines in English.
Acquisition is to learn a language without studying it, just by hearing and/or reading it and then using it. This is the way people usually learn their first language.
To pick up a language is to learn a language without studying it, just by hearing and/or reading and then using it. This is the way we learn our first language.
