The intention of this research is to shed light on what notions the linguists’ and grammarians had thought , imagined and put into there minds about illusion . They used these notions in order to interpret linguistic and morphological phenomena in the Arabic speech that departed form Arab’s habits and convention which they used to call abnormals and/or anecdotes in an attempt to subjugate them to the popular standards of analogy .

Such phenomena are, in my convention, nothing but speech patterns, from or styles approved and used in Arabic, and known by experts and those who cares for it . They are also evidences of Arabic  vastness and rhetorical versatility
