This study aims at investigating the contemporary efforts of Arabic writing system from a linguistic perspective. The study is distinguished from previous studies by treating the writing system as a linguistic one with its own linguistic features. Thus, the study has revealed the consonant feature of Arabic writing and its relation to derivation, inflection, and dialectal variation. Therefore, the researcher concludes that proposals of replacing Arabic alphabet by Latin alphabet or modification of Arabic orthography are non-linguistic which are related to contemporary issues like learning, the printing, translation and culture. These efforts should have examined Arabic writing as a representative of a linguistic system. Consequently, the researcher concludes that Arabic orthography system can preferably represent the linguistic system.
