Second-language Acquisition
Second-language acquisition (SLA), sometimes called second-language learning—otherwise referred to as L2 (language 2) acquisition, is the process of learning a language other than one's native language (L1).

SLA research spans cognitive, social, and linguistic perspectives. Cognitive approaches investigate memory and attention processes; sociocultural theories emphasize the role of social interaction and immersion; and linguistic studies examine the innate and learned aspects of language.
