Syn. -- Ludicrous; laughable; amusing; ridiculous -- Risible, Ludicrous, Ridiculous. Risible differs from ludicrous as species from genus; ludicrous expressing that which is playful and sportive; risible, that which may excite laughter. Risible differs from ridiculous, as the latter implies something contemptuous, and risible does not.
