Pronunciation

Forms

châtain (feminine (rare) châtaine or (obsolete) chataigne, masculine plural châtains, feminine plural (rare) châtaines or (obsolete) chataignes)[1] First found as a feminine adjective chastaigne (late 12th or early 13th century); masculine chastain before 1345; the feminine châtaine only from 1839, in Balzac.[2][3][4]

Etymology

It is a back-formation from French châtaigne (“chestnut”): the noun was used as an adjective beside feminine nouns, and a masculine adjective was made from it, as happened with violet; the feminine châtaine was then made from the masculine.[2][5][3][1] The Petit Robert and Wiktionary also point to Latin castaneus.[6][1]

The noun itself is from Latin castanea, which is from Ancient Greek κάστανον (kástanon).[5]

Earliest recorded meaning

The Covenant Vivien (late 12th or early 13th century) has espee chastaigne, a chestnut-coloured sword; the word was very rare at first.[2][3]

Semantic evolution

Before 1345 a manuscript of Rutebeuf has the masculine chastain of wine, and Christine de Pizan writes chasteins en couleur.[2][7] The adjective came to be used mostly of hair that is neither fair nor dark, and of a person with such hair.[3][2] Richelet stated in 1680 that it was used only in the masculine,[2] and Littré still gave it as masculine only, but châtaine is found from Balzac (1839) on and passed into literary use.[2][7][8] As a noun it has meant a person with chestnut hair, and the colour itself, since 1704.[2][3]
