The desire to learn is often related to the concept of motivation. Motivation is the most-used concept for explaining the failure or success of a language learner. Second language (L2) refers to a language an individual learns that is not his/her mother tongue, but is of use in the area of the individual. (It is not the same as a foreign language, which is a language learned that is not generally spoken in the individual's area.) Research on motivation can treat the concept of motivation as an internal process that gives behavior energy, direction and persistence (in other words, motivation gives behavior strength, purpose, and sustainability). Learning a new language takes time and dedication. Once achieved, fluency in a second language offers numerous benefits and opportunities. Learning a second language is exciting and beneficial at all ages. It offers practical, intellectual and many aspirational benefits. In learning a language, there can be one or more goals – such as mastery of the language or communicative competence – that vary from person to person. There are a number of language learner motivation models that were developed and postulated in fields such as linguistics and sociolinguistics, with relations to second-language acquisition in a classroom setting. The different perspectives on L2 motivation can be divided into three distinct phases: the social psychological period, the cognitive-situated period and the process-oriented period.
