These are argued to have direct impact acquisition basic reading processes in Arabic. then reviews recent psycholinguistic research addressing directly effect evidence reviewed demonstrates children’s phonological awareness recoding skills affected by affiliation target unit (Standard versus Spoken). As such, find structures only available significantly more difficult process than those familiar them from their spoken vernacular.
