  1. Nunation. ============

When a noun or an adjective is indefinite it carries Nunation, which is any of the short vowels plus /n/ sound.

(a)** ** -ٌٌ indicates Nominative case as in استاذةٌ

(b) ** ** indicates Accusative case as in استاذةً

(c)**-ٍ ** ** ** indicates Genitive case as in  ** ** استاذةٍ

Please notice that the accusative Nunation    is always written on (ا ) as inبيتاً . An exception to that is when the final consonant is either the feminine marker, Taa' MarbuTaطالبة ً , or Hamza,سماءً
