petite adj.

late 14c., "small, little; minor, trifling, insignificant," from Old French petit "small, little, young, few in numbers" (11c.), which is probably from the stem of Late Latin pitinnus "small," a word of uncertain origin; it corresponds to no known Latin form and perhaps is from a Celtic root pett- "part, piece, bit" also found in Italian pezza, English piece.

Attested as a surname from 1086. Replaced by petty in most usages, except in established forms such as petit bourgeois "conventional middle-class" (1832; used in English by Charlotte Brontë earlier than by Marx or Engels); petit mal ("mild form of epilepsy," 1842, literally "little evil"); petit-maître ("a fop, a dandy," 1711, literally "little master"); and petit four "small, fancy dessert cake" (1884), which in French means "little oven," from Old French four "oven," from Latin furnus. In Middle English a petiteskole (mid-15c.) was a school for young children.
