Ridiculous → It is formed from "ridere" (meaning to laugh) and the suffix "-ous" (meaning full of). The word "ridiculous" means full of laughter or deserving to be laughed at, often implying something is absurd or nonsensical.
Think of something that makes you 'laugh' ('ridere') and is 'full of' ('-ous') absurdity — that's why ridiculous means something that is laughably absurd.
