Language Acquisition Device

The Langauge Acquisition Device is an inborn capacity (a genetic mechanism or apparatus) which is present in the brain right from the beginning and which enables children (by the age of 3 to 4) to extract the rules of language from speech when they are exposed to it and to use them productively. Animals do not possess this capacity.

Langue

Langue refers to the abstract system shared by all the speakers of the same language, like English, Arabic, French, etc. It is an underlying system of abstract rules of lexicon, grammar and phonology which is implanted in each individual’s mind resulting from his nurture in a given speech community.
