Hi,
What's relationship between these three concepts, Approximative system, Interlanguage and Idiosyncratic system?
Mehrgan has a point.
As you may remember, I've already mentioned both Interlanguage and Idiosyncrasy in other posts.
Approximate system was first hypothesized by Nemser, and emphasizes the continual development of language through systematic stages. What a learner learns may undergo modifications and may be restructured gradually. The main difference between interlanguage and Aproximate system hypothesis lies in the fact that the former believes the learner's language is a phenomenon between the first and second languages (intermediate status), while the latter emphasizes the dynamic essence of the learner's language (transitional and developmental) .
The theory of Idiosyncratic dialect, proposed by Pit Corder, maintains that each learner possesses her particular and unique system of language. language of poems, aphasic speech, and peculiarities of an infant's language learning his mother tongue all fall into this category. A learner's sentences may be well-formed, but idiosyncratic (
covert), or may be superficially ill-formed (
overt). If the case is something other than the two conditions, the learner's language will be considered to be non-idiosyncratic, which is an acceptable state.
Matters beyond the language-learner's mother tongue usually come to play; for example, the subject matter and the manner of teaching are thought to be effective, according to this theory.
