"pollen-bearing organ of a flower," 1660s, from Modern Latin (1625, Spigelus), from Latin stamen "stamen" (Pliny), literally "foundation in weaving, thread of the warp" in the upright loom (related to stare "to stand"), from PIE *sta-men- (source also of Greek stēmōn "warp in the upright loom," also used by Hesychius for some part of a plant, Gothic stoma, Sanskrit sthaman "place," also "strength"), from root *sta- "to stand, make or be firm." The usual English plural is stamens because of the special use of the classical plural, stamina.
