The word 好笑 is formed by directly combining two independent concepts: 好 (hǎo), meaning "good" or "well", and 笑 (xiào), meaning "to laugh" or "laughter". Their union creates a new, fused meaning where 好 acts not as a standalone adjective but as an intensifier describing the nature of the action, so the compound literally reads as "laugh-worthy" or "well-suited for laughter", effectively conveying the idea of something being funny or ridiculous.
