Exception (Istithna) in Arabic

Overview

Exception (الاستثناء, al-istithna') is the grammatical structure for expressing "except" or "other than" in Arabic. The main exception particle is إلا (except), with غير and سوى as alternatives. The case of the excepted noun depends on whether the sentence is complete and affirmative, complete and negative, or incomplete.

At the B2 level, understanding exception rules demonstrates command of Arabic's case system. In a complete affirmative sentence, the excepted noun is accusative: جاء الجميع إلا زيدًا (everyone came except Zaid). In a complete negative sentence, the excepted noun can match the case of the noun before إلا: ما جاء أحد إلا زيدٌ (no one came except Zaid, nominative).

This topic brings together case marking, negation, and sentence analysis in a way that deepens your overall Arabic grammar skills.
