arabiser

To Arabize — to make something Arabic in language or character, most often discussed in the context of language policy (arabiser l'enseignement, education policy replacing French with Arabic) in North African and Middle Eastern countries.

• Le pays a arabisé son système éducatif après l'indépendance. — The country Arabized its education system after independence.
• Ce mot a été arabisé avant d'entrer dans la langue locale. — This word was Arabized before entering the local language.
• La politique d'arabisation a modifié l'administration. — The Arabization policy changed the administration.

This is a politically and historically loaded term in Maghreb contexts (Algeria, Morocco, Tunisia), tied to post-colonial language policy — learners encountering it in news or history texts should read it with that specific background in mind, not as a neutral linguistic term.
