Origin of federal
First recorded in16205–30; earlier foederal, from Latin foeder- (stem of foedus ) “formal agreement, treaty, league” + -al1
historical usage of federal
English federal comes from the Latin noun foedus (stem foeder- ) “a formal agreement between states, peoples, or private persons, a league, treaty (of alliance or peace), a marriage compact.” Foedus is related to the Latin verb fīdere “to trust, trust in, have confidence in,” the adjective fīdus “faithful loyal” (Abraham Lincoln owned a dog named Fido), and the noun fidēs “trust, state of being trusted.” Latin fidēs is the ultimate source of English words such as fidelity, fealty, infidel, and faith. The earliest use of federal had to do with a treaty or covenant, especially a covenant between God and an individual. The meaning “relating to a union of states under a central government” appeared in 1703, probably arising from the contextual meaning of the term federal union —in other words, a union based on a treaty. Soon after American independence, federal was used to refer specifically to the national government of the United States.
