تلب

تَوْلَبٌ تولب , perfectly decl. [when used as a proper name as well as when used as an appellative], because it is of the measure فَوْعَلٌ; (Sb, S;) for we judge its ت to be a radical, and its و to be augmentative, because فَوْعَل is more common [as the measure of a noun] than تَفْعَل; (M;) but accord. to Suh, the ت is a substitute for و, and, if so, it should be mentioned in art. ولب; (TA;) A young ass; syn. جَحْشٌ: (S, K:) or the foal of a wild ass, when he has completed a year. (M.) And أُمُّ تَوْلَب is an appellation given to The she-ass. (S.) ― -b2- The former is sometimes metaphorically applied to (tropical:) A [ young ] man: (M:) or a boy. (S.)
