وَهْمٌ

A thought, or an idea, occurring in the mind: (Mgh, Msb, * K: *) plural أَوْهَامٌ: (Msb:) or of the two extremes [or different opinions or ideas] between which one wavers, that which is outweighed [in probability]. (K.) An [indecisive] opinion or idea outweighed in probability [or formed from evidence outweighed in probability; a presumption; a surmise; a fancy; a supposition]: opposed to ظَنٌّ, q. v. (Kull, p. 376.)

Also Doubt, or suspicion: but for this I have found no authority; though it is well known, and plainly indicated in the Msb, in article خيل; voce خَيَّلَ, q. v. in this Lex.

Also The object of a thought, or of an idea, occurring in the mind. (Mgh.) And The mind itself, or intellect; synonym عَقْلٌ. (MF, TA.) In modern Arabic it signifies An imagination, a fancy, a chimera, and a conjecture.
