英文词源

tan

tan: [OE] Tan was borrowed into late Old English from the medieval Latin verb tannāre. This was derived from tannum ‘oak bark’ (oak bark is used in tanning leather), which itself was probably a loan-word from Gaulish tanno- ‘oak’. The French noun tan ‘tan’ came ultimately from the same Latin source. From it was derived tanin, acquired by English as tannin [19]; and its immediate Old French predecessor formed the basis of an adjective tané ‘tancoloured, dark’, whose Anglo-Norman version tauné gave English tawny [14].
=> tannin, tawny

tan (v.)

late Old English tannian "to convert hide into leather" (by steeping it in tannin), from Medieval Latin tannare "tan, dye a tawny color" (c.900), from tannum "crushed oak bark," used in tanning leather, probably from a Celtic source (such as Breton tann "oak tree"). The meaning "make brown by exposure to the sun" (as tanning does to hides) first recorded 1520s; intransitive sense also from 1520s.
