Wont

The word wont, not to be confused with want, has several meanings, but it is most often used as an adjective, usually followed by to and meaning accustomed, given, or likely—for example:

“Stats are for losers,” as head coach John Fox is wont to say. [Panthers.com]

It made me introspective, as talks with Kris are wont to do. [Chiron Training]

Wont may also be a noun, its definition being habit or accustomed behavior—for example:

Kerry, as is his wont, offered a turbid synonym … [Emory Wheel]

And wonted has another adjectival use, meaning usual or habitual:

Sofiane Sylve lent the sugar plum fairy the wonted regality and line without completely dispensing a generosity of spirit. [San Francisco Chronicle]

Dictionaries list a verb sense of wont—namely, to make accustomed to—but this definition is archaic.
