Etymology

It is inherited from Middle English tannen, from late Old English tannian, implied in getanned,[2][3][4] from Medieval Latin tannāre, to tan, dye a tawny colour (about 900),[3][2] from tannum, crushed oak bark used in tanning,[3][2] probably from a Celtic source, such as Breton tann, oak tree;[3][2][5] it was reinforced in Middle English by Old French tanner.[4][6]

Earliest recorded meaning

To make hides into leather: about 1000, in Ælfric's glossaries, as the participle getanned.[2][7]

Semantic evolution

To make the skin brown by exposure to the sun is first recorded in 1530, in Palsgrave.[2][3] To tan someone's hide, to thrash, is from the 1660s.[3][4] The noun, crushed oak bark, is from 1604 (about 1600),[2][7][3] earlier in tannedust (1392).[2] The brown colour of tanned skin is from 1749,[2][3][7] in allusion to the colour of tanned leather,[2] and the adjective, yellowish-brown, from 1630.[2] Tanner and tannery are early: tanner is Old English, tannery 15th century.[4] German Tanne, fir tree, may come from the same Celtic source.[3]
