  Word History: In modern English, metal and mettle are pronounced the same, and

  they are in fact all related. Middle English borrowed metal from Old French in

  the 14th century; Old French metal, metail, came from Latin metallum, from

  Greek metallon, "mine, quarry, ore, metal." By the 16th century, metal had

  also come to mean "the stuff one is made of, one's character," but there was

  no difference in spelling between the literal and figurative senses until

  about 1700, when the spelling mettle, originally just a variant of metal, was

  fixed for the sense "fortitude." The history of English has numerous examples

  of pairs of words, like metal and mettle, that are spelling variants of the

  same word; two other such pairs are trump/triumph, and through/thorough.
