The following outline is provided as an overview of and topical guide to second-language acquisition: Second-language acquisition – process by which people learn a second language. Second-language acquisition (often abbreviated to SLA) also refers to the scientific discipline devoted to studying that process. ''Second language'' refers to any language learned in addition to a person's first language, including the learning of third, fourth, and subsequent languages. It is also called second-language learning, foreign language acquisition, and L2 acquisition. == What is second-language acquisition? == Second-language acquisition can be described as all of the following: * Language acquisition – process by which humans acquire the capacity to perceive and comprehend language, as well as to produce and use words and sentences to communicate. Language acquisition is one of the quintessential human traits, because nonhumans do not communicate by using language. * Academic discipline – branch of knowledge that is taught or researched at the college or university level. Also called a ''field of study''. Disciplines are defined (in part) and recognized by the academic journals in which research is published, and the learned societies and academic departments or faculties to which their practitioners belong. A discipline incorporates relevant knowledge, expertise, skills, people, projects, communities, problems, challenges, studies, inquiry, approaches, and research areas. * Branch of science – systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. "Science" also refers to a body of knowledge itself, of the type that can be rationally explained and reliably applied. * * Branch of social science – academic discipline concerned with the society and the relationships of individuals within a society, which primarily rely on empirical approaches. * * * Branch of linguistics – scientific study of human language. * * * * Branch of applied linguistics – interdisciplinary field of study that identifies, investigates, and offers solutions to language-related real-life problems. Some of the academic fields related to applied linguistics are education, linguistics, psychology, computer science, anthropology, and sociology. * A form of language education – teaching and learning of a foreign or second language. Language education is a branch of applied linguistics. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Outline of second-language acquisition」の詳細全文を読む スポンサード リンク
