Wont
Old English gewunod, past participle of wunian, ‘dwell, be accustomed’, of Germanic origin.
wiktionary
Origin uncertain; apparently a conflation of wone(“ custom, habit, practice”) and wont ( participle adjective, below). Compare German Low German Gewohnte(“custom, habit”) and Dutch gewoonte. Likely related to wone, wonder, wean, and win, ultimately from Proto-Indo-European *wenh₁-(“to wish for, strive for, pursue; to succeed, win”); more there.
