Abstract:
The contact of languages in a given geographic area is the basis of linguistic facts, such as bilinguism or linguistic borrowing. Our search here, tries to withdraw this last phenomenon and to show on one hand, that the algerian speaker in this everyday speech in dialectal arabic, uses lexical parts or phrastic segments belonging to a scientific an technical french vocabulary. On
the other hand, this use goes with a semantic split due to the undergoing of this items from a special field to a more fluctuant and larger one. Thus they may tend to be diffused. The speaker, in such a particular way, uses all linguistic means such as metaphor, analogy or word associations to split this vocabulary from specialised to a current language.
