Origin of the word Tier

  1. "row, rank, range," 1569, from M.Fr. tire, from O.Fr. tire "rank, sequence, order" (c.1210), probably from tirer "to draw, draw out" (see tirade). Some suggests the O.Fr. noun is from a Gmc. source akin to O.H.G. ziari, Ger. Zier "adornment," O.E. tir "glory, honor." more
