QUESTION3-Discuss the process of acquisition of a second language. Describe the benefits of multilingualism.

ANS- Second-language acquisition (SLA), second-language learning, or L2 (language 2) acquisition, is the process by which people learn a second language. Second-language acquisition is also the scientific discipline devoted to studying that process. The field of second-language acquisition is a subdiscipline of applied linguistics, but also receives research attention from a variety of other disciplines, such as psychology and education.

A 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 that it is a complete language system in its own right, with its own systematic rules. This interlanguage gradually develops as learners are exposed to the targeted language. 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. However, languages that learners already know can have a significant influence on the process of learning a new one. This influence is known as language transfer.

The primary factor driving SLA appears to be the language input that learners receive. Learners become more advanced the longer they are immersed in the language they are learning, and the more time they spend doing free voluntary reading. The input hypothesis developed by linguist Stephen Krashen makes a distinction between language acquisition and language learning (acquisition–learning distinction), claiming that acquisition is a subconscious process, whereas learning is a conscious one. According to this hypothesis, the acquisition process in L2 is the same as L1 (Language 1) acquisition. The learning process is consciously learning and inputting the language being learned. However, this goes as far as to state that input is all that is required for acquisition. Subsequent work, such as the interaction hypothesis and the comprehensible output hypothesis, has suggested that opportunities for output and for interaction may also be necessary for learners to reach more advanced levels.
