UK: ˌwɔːn ˈaʊt | US: ˌwɔːrn ˈaʊt
adj. (of an object) damaged or weakened from prolonged use; no longer functional.
adj. (of a person) extremely tired; exhausted.
The word "worn-out" combines "worn," the past participle of "wear" (from Old English werian, meaning "to carry or have on the body"), with "out," an adverb intensifying the sense of depletion. Originally literal (objects eroded by use), it later extended metaphorically to describe human fatigue. The logic mirrors physical erosion translating to human energy depletion.
