Etymology

The word traces back to the Latin accidere, which metaphorically linked "falling" (cadere) to unforeseen events. Over time, accident evolved to mean "unplanned occurrence," with -al and -ly later added to form the adverbial form. The progression reflects a shift from physical falling to abstract happenings.
