A person who dyes fabric or other materials; a dyer (archaic or variant spelling).
From Middle English 'dyen' (to dye) + -er (one who does something). Related to Old English 'deag' (to dye), with roots possibly connecting to Proto-Indo-European color terminology.
Medieval diers were among the wealthiest artisans in Europe because they controlled secrets of color that were worth their weight in gold—a single batch of indigo or Tyrian purple could make a small fortune.
