A wont is a custom or habit, like my wont to drink at least ten cups of coffee a day. (In this particular example, some people might call my wont an addiction.)

Pronunciation: / wɔnt/
English description: an established custom
Synonyms: habit
Chinese Translation: 习惯(xi2 guan4)
Spanish Translation: la costumbre
ORIGIN: Wont is a tricky word, in terms of pronunciation; some people argue it sounds like want, while others insist it's pronounced like won't. Perhaps the confusion over pronunciation explains why this word is used relatively infrequently in everyday speech. It's most people's wont to use a synonym like custom or habit.

EXAMPLE SENTENCE:

He spins off his marker in midfield and, as is his wont, powers towards the Spain penalty area.
But they also like to talk — sometimes quite a lot — as well-educated and successful people are wont to do.
