Imāla

Imāla (also transliterated imālah ; Arabic: إمالة‎, literally "slanting") is a vowel shift exhibited in many dialects of Arabic, where the open vowel, be it long or short, is raised to or even in certain morphological or phonological contexts. Imāla occurs in modern colloquial as well as classical variants of Arabic, including several qirāʾāt ("styles of recitation") of the Quran. As a very noticeable phenomenon, imāla is often one of the most distinguishing features in dialects in which it occurs, such as Lebanese Arabic.
