Interlanguage

Article summary

An interlanguage is an idiolect developed by a learner of a second language (L2) which preserves some features of their first language (L1) and can overgeneralize some L2 writing and speaking rules. These two characteristics give an interlanguage its unique linguistic organization. It is idiosyncratically based on the learner's experiences with L2. An interlanguage can fossilize, or cease developing, in any of its developmental stages. Several factors can shape interlanguage rules, including L1 transfer, previous learning strategies, strategies of L2 acquisition, L2 communication strategies, and the overgeneralization of L2 language patterns. Interlanguage theory posits that a dormant psychological framework in the human brain is activated with study of a second language. The theory is credited to Larry Selinker, who coined the terms interlanguage and fossilization. Uriel Weinreich is credited with providing the basis for Selinker's research. Selinker noted in 1972 that in a given situation, the utterances of a learner differ from those of a native speaker to convey an identical meaning. This comparison suggests a separate linguistic system, which can be observed in the utterances of a learner attempting to convey meaning in L2. It is not seen when the learner performs form-focused tasks, such as oral drills in a classroom.…
