The order in which learners acquire features of their new language stays remarkably constant, even for learners with different native languages and regardless of whether they have had language instruction.
This interlanguage gradually develops as learners are exposed to the targeted language. The field of second-language acquisition is regarded by some but not everybody as a sub-discipline of applied linguistics but also receives research attention from a variety of other disciplines, such as psychology and education.Ī central theme in SLA research is that of interlanguage: the idea that the language that learners use is not simply the result of differences between the languages that they already know and the language that they are learning, but a complete language system in its own right, with its own systematic rules.
Second-language acquisition is also the scientific discipline devoted to studying that process. Second-language acquisition ( SLA), sometimes called second-language learning - otherwise referred to as L2 ( language 2) acquisition, is the process by which people learn a second language.
