haughty (adj.)

"proud and disdainful," 1520s, a redundant extension of haught (q.v.) "high in one's own estimation" by addition of -y (2) on model of might/mighty, naught/naughty, etc. Middle English also had hautif in this sense (mid-15c., from Old French hautif), and hautein "proud, haughty, arrogant; presumptuous" (c. 1300), from Old French hautain.
