headquarter

The word 'headquarter' is a back-formation from the noun 'headquarters'. The noun 'headquarters' originated in the mid-17th century, combining 'head', meaning the chief or principal part, with the plural form of 'quarter', which in a military context denoted a station or place of residence for troops. The literal sense was thus "the chief station or residence," the central place from which orders are issued. The verb 'to headquarter' emerged later, in the 19th century, meaning to establish or locate one's central offices in a specific place, reflecting the word's evolution from a physical military base to the administrative center of any organization.
