Etymology

Origin of sergeant

1150–1200; Middle English sergant, serjant, serjaunt < Old French sergent < Latin servient- (stem of serviēns ), present participle of servīre. See serve, -ent

Explanation

Sergeant describes a certain rank for a police or military officer. If you've been promoted to sergeant, congratulations are in order. Sergeant comes from the Old French sergent and originally from the Latin verb servire meaning "to serve," as in "to serve and protect," a police sergeant's job. Remember that sergeant is spelled with an "e" after the "s" (it's often misspelled with an "a").
