Weld


Definition:

  • (v. t.) To wield.
  • (n.) An herb (Reseda luteola) related to mignonette, growing in Europe, and to some extent in America; dyer's broom; dyer's rocket; dyer's weed; wild woad. It is used by dyers to give a yellow color.
  • (n.) Coloring matter or dye extracted from this plant.
  • (v. t.) To press or beat into intimate and permanent union, as two pieces of iron when heated almost to fusion.
  • (v. t.) Fig.: To unite closely or intimately.
