In a way that is narrow-minded or lacking in generosity, often refusing to accept different ideas or opinions.
The policy was implemented illiberally, restricting freedom of expression.
Illiberally → It is formed from "il-" (meaning not) and "liberalis" (from Latin, meaning generous or free). The word "illiberally" means in a manner that is not generous or free, often implying a lack of openness or tolerance.
Think of 'not' ('il-') being combined with 'generous' ('liberalis') to remember that 'illiberally' means acting in a way that is not generous.
