algae (n.)
(plural), 1794, from alga (singular), 1550s, from Latin alga "seaweed," which is of uncertain origin. Perhaps connected to Latin ulva "grass-like or rush-like aquatic plant," or perhaps from a PIE root meaning "to putrefy, rot," but de Vaan considers this unlikely and suggests it might be a foreign loan-word.
