"Wont to" is an outdated phrase that means inclined or accustomed to a particular habit or behaviour. There are plenty of synonyms that can be used to replace it, such as accustomed, familiar, habitual, used to, inclined, prone, and predisposed. All these words convey the idea that someone has developed a routine or tendency towards certain actions and are comfortable doing so. Another way to express this could be to say someone has a proclivity for something, which implies a natural inclination or tendency. In summary, "wont to" is an old-fashioned term that can be easily substituted with more contemporary language.
