خاصي في نفسه غريب لا ينال إلا بفكر
A distinctive, rare idea reached only through reflection.
When the method of conveying a meaning is unusual and intellectually inventive, matching it exactly differs from using a known convention. Conversely, an ordinary image may become distinctive through a poet's transformation, arrangement or elaboration.
A rare idea and a familiar idea given a rare treatment therefore require distinct analysis. The question is precisely which special feature has been taken.
