لَهْوٌ
1.
Diversion; pastime; sport; play: or especially, such as is vain, or frivolous; idle sport: (from various explanations:) what occupies a man so as to divert him from that which would render him sad or solicitous, &c.: (TA:) or relief of the mind by means which wisdom does not require: this [it is said] is the original signification: (Et-Tarasoosee, Msb:) a thing in which a man delights himself, and which occupies him so as to divert him, and then ceases. (KT.) It has a more general application than لَعِبٌ: for example, the hearing of musical instruments or the like is لَهْوٌ, but not لَعْبٌ. (TA.)
