Etymology

Earliest recorded meaning

It is first found in 1790 in the Moniteur, meaning “forming a supplement, additional”.[2][3] Bloch and Wartburg and the GLLF date it to 1792.[5][6]

Semantic evolution

In 1810 the Penal Code used it for a person appointed to stand in for another, as with jurés supplémentaires, a sense now replaced by suppléant.[2][6][4] Geometry has angles supplémentaires, two angles adding up to a straight angle (1875).[2][4] Music has lignes supplémentaires “ledger lines” (1837).[2] The phrases train supplémentaire (1894) and heures supplémentaires “overtime” (1938) followed.[2]
