Word Origin and History for tiering



"row, rank, range," 1560s, from Middle French tire, from Old French tire "rank, sequence, order" (early 13c.), probably from tirer "to draw, draw out" (see tirade). Some suggests the French noun is from a Germanic source akin to Old High German ziari, German Zier "adornment," Old English tir "glory, honor."
