c.1000, from Latin gladiolus “wild iris,” literally “small sword,” diminutive of gladius “sword” (see gladiator); so called by Pliny in reference to the plant’s sword-shaped leaves. The Old English form of the word was gladdon. Form gladiol is attested mid-15c.; the modern use perhaps represents a 1560s reborrowing from Latin.
