chestnut

Etymology and origin of the English word chestnut

Pronunciation

  • IPA: /ˈt͡ʃɛs(t)nʌt/ (UK); /ˈt͡ʃɛs(t)ˌnʌt/ (US)[1]

Etymology

Formed from chesten nut (1519),[2][3] from inherited from Middle English chesteine and nut,[4][2][3][5] borrowed from Old French chastaigne,[4][2][3] from Latin castanea (“chestnut, chestnut tree”),[4][2][3][5][6] from Ancient Greek καστανέα (kastanéa, “chestnut tree”).[4][2][3][5] The Greeks explained it as “nut from Castana” or “from Castanea”, place names, but these are probably named after the trees,[3] and the word is probably borrowed from a language of Asia Minor (compare Armenian kask “chestnut”).[2][3]

Earliest recorded meaning

The edible nut of the chestnut tree (1519).[7][2]

Semantic evolution

The name passed to the tree (1578) and its wood (1823),[7] and to the reddish-brown colour, as an adjective by 1555 and a noun from the 1650s.[5][3] It was applied to the horse chestnut from 1832[7][3] and to the hard knob on the inside of a horse's foreleg (1859).[7] The slang sense “old, often-repeated joke” is from 1885 in the United States;[3] the actor Joseph Jefferson traced it to a scene in the 1816 melodrama The Broken Sword in which a character keeps retelling a story involving a chestnut tree.[3]
