overhaul
UK: ˌəʊvəˈhɔːl | US: ˌoʊvərˈhɔːl
vt. to examine thoroughly and make repairs or improvements
n. a comprehensive examination or restoration
The word "overhaul" originated in the 17th century, combining "over" (implying thoroughness or excess) and "haul" (from Old English halian, meaning "to pull or drag"). Initially used in nautical contexts to describe the act of pulling ropes or sails for inspection, it later expanded to mean any exhaustive examination or repair. The logic reflects pulling something apart ("haul") completely ("over") to assess or restore it.
