«التشبيه الدلالة على مشاركة أمر لأمر في معنى»
Simile is an indication that one thing shares a meaning or quality with another.
Sharing (مشاركة) does not make the two objects identical in every respect. The comparison picks out a particular attribute. “Zayd is brave like a lion” does not assert that Zayd belongs to the biological species of lions; it evokes resemblance in courage.
One term is ordinarily the subject being characterized and the other supplies a recognized model for the quality. Unless the relevant point of similarity can be identified, the comparison risks remaining vague.
