'headquarters' originates from the combination of 'head' and 'quarters,' where 'head' refers to the main or leading part, and 'quarters' refers to a place of residence or station.

'headquarters' evolved from the military term used to describe the place where the commanding officer's quarters were located.

Initially, it meant 'the place where the commanding officer's quarters were located,' but over time it evolved into its current meaning of 'main office or center of operations.'
