Purpose and Reason Clauses in Arabic

Overview

Purpose and reason clauses express why an action is performed (reason) or what it aims to achieve (purpose). Arabic uses specific particles for each: purpose is expressed with لِـ/كي/لكي/حتى + subjunctive, while reason uses لأنّ (because), إذ (since), and بسبب (because of).

At the B2 level, these clauses are essential for constructing logical arguments and explaining motivations. The purpose particles (لـ, كي, لكي, حتى) trigger the subjunctive mood on the following verb: جئت لأتعلمَ العربية (I came to learn Arabic). Reason particles introduce explanatory clauses: تأخر لأنّه مريض (he was late because he is sick).

Distinguishing between purpose and reason is important: purpose looks forward (in order to), while reason looks backward (because). Arabic marks this distinction grammatically.

How It Works

Expressing purpose: لـ/كي/لكي (in order to) + subjunctive, حتى (so that). Reason: لأن (because), إذ (since), بسبب (because of).
