Forms

frontière f (plural frontières)[1]

Etymology

It is from French front + -ière.[2][3][1][4] The modern sense probably comes from phrases meaning “frontier country” (1405), a country guarded by an army or a fortress facing the enemy, rather than from the feminine of the Middle French adjective frontier (“bordering”);[2][3][5] Bloch and Wartburg, however, derive it from that adjective.[6] The noun front is inherited from Latin frōns (“forehead”).[6]

Compare Catalan frontera, Spanish frontera, Portuguese fronteira and Italian frontiera.[1]

Earliest recorded meaning

In the Faits des Romains (about 1213) a frontiere is the front line of an army.[2][3][6]

Semantic evolution

In 1292 the word was used of a fortified place facing the enemy.[2][3] Littré explains the shift: faire frontiere meant to draw up in battle order, and since this was done above all on the edges of a country, the word came to mean the limit between states.[7] That sense appears in Froissart about 1360 and in Eustache Deschamps at the end of the 14th century.[8][2]

By extension it was said of the limits of a region and of language boundaries (1770), and figuratively of a line dividing abstract or concrete domains (1700).[3][8] The compound garde-frontière is recorded in 1854, and in Swiss French it is a calque of German for a member of the border police.[3] Frontalier (1730) is not formed on it but borrowed from Provençal.[6]
