Arabic grammar

Arabic grammar (Arabic: النحو العربي‎ an-naḥw al-‘arabī or قواعد اللغة العربية qawā‘id al-lughah al-‘arabīyah) is the grammar of the Arabic language. Arabic is a Semitic language and its grammar has many similarities with the grammar of other Semitic languages.

The article focuses both on the grammar of Literary Arabic (i.e. Classical Arabic and Modern Standard Arabic, which have largely the same grammar) and of the colloquial spoken varieties of Arabic. The grammar of the two types is largely similar in its particulars. Generally, the grammar of Classical Arabic is described first, followed by the areas in which the colloquial variants tend to differ (note that not all colloquial variants have the same grammar). The largest differences between the two systems are the loss of grammatical case; the loss of the previous system of grammatical mood, along with the evolution of a new system; the loss of the inflected passive voice, except in a few relic varieties; and restriction in the use of the dual number.
