معنا
Possibility means that something can happen or can be done, without saying that it will. It can describe what might be true or what the situation makes possible. Languages use helper verbs, endings, or words such as maybe, and some have no special verb form for this. Unlike Ability, Possibility need not depend on anyone's skill or strength.
