haughty: [16] To be haughty is to be ‘above oneself’, or, to put it another way, to be ‘on one’s high horse’. For etymologically, haughty means simply ‘high’. It is an alteration of an earlier, now dead English adjective haught, which was borrowed from Old French haut ‘high’, a descendant of Latin altus (whence English altitude).

"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.
