horrid adj.
early 15c., "hairy, shaggy, bristling," from Latin horridus "bristly, prickly, rough, horrid, frightful, rude, savage, unpolished," from horrere "to bristle with fear, shudder" (see horror). Meaning "horrible, causing horror" is from c. 1600. Sense weakened 17c. to "unpleasant, offensive."
