agave (n.) Look up agave at Dictionary.com
American aloe plant, 1797, from Latin Agave, from Greek Agaue, proper name in mythology (mother of Pentheus), from agauos "noble, illustrious," a word of uncertain origin, perhaps from agasthai "wonder at," from gaiein "to rejoice, exult," with intensive prefix a-. The name seems to have been taken generically by botanists, the plant perhaps so called for its "stately" flower stem.
