![]() ![]() This is distinguished from second-language acquisition, which deals with the acquisition (in both children and adults) of additional languages. Language acquisition usually refers to first-language acquisition, which studies infants' acquisition of their native language, whether that be spoken language or signed language, though it can also refer to bilingual first language acquisition (BFLA), which refers to an infant's simultaneous acquisition of two native languages. state "The question of how these structures are acquired, then, is more properly understood as the question of how a learner takes the surface forms in the input and converts them into abstract linguistic rules and representations." ![]() Linguists who are interested in child language acquisition have for many years questioned how language is acquired. There are two main guiding principles in first-language acquisition: speech perception always precedes speech production, and the gradually evolving system by which a child learns a language is built up one step at a time, beginning with the distinction between individual phonemes. These three mechanisms are: relativization, complementation and coordination. Evidence suggests that every individual has three recursive mechanisms that allow sentences to go indeterminately. Even though human language capacity is finite, one can say and understand an infinite number of sentences, which is based on a syntactic principle called recursion. Human language capacity is represented in the brain. Language can be vocalized as in speech, or manual as in sign. ![]() The capacity to use language successfully requires one to acquire a range of tools including phonology, morphology, syntax, semantics, and an extensive vocabulary. Language acquisition involves structures, rules, and representation. Language acquisition is the process by which humans acquire the capacity to perceive and comprehend language (in other words, gain the ability to be aware of language and to understand it), as well as to produce and use words and sentences to communicate. ![]()
