amused

the word amused originates from the old french muser, which meant to ponder, stare in wonder, or even to waste time, possibly linked to the idea of an animal standing with its muzzle in the air. the latin prefix ad- (to, towards) was added, forming amuser, which evolved to mean "to divert the attention, beguile, or entertain." the past participle form amused thus came to describe the state of having one's attention pleasantly diverted or occupied by something entertaining or comical. the semantic journey moved from a sense of idle staring or wonderment to the modern, more specific sense of finding something humorous or enjoyable.

Structure: a (towards) + muse (to think/stare) + ed (adjective suffix) a- (from latin ad-, meaning "to, towards"), muse (from old french muser, meaning "to ponder, stare, or waste time", of uncertain origin, possibly from a vulgar latin root related to the muzzle of an animal), -ed (old english past participle/adjective-forming suffix).
