Using the word in parentheses, we can rewrite the sentence in the following manner while maintaining the meaning:
Mike is keen on playing football.
What does "keen" mean?
- We say someone is "keen on something" when that person is very interested in that thing. Therefore, it is a good way to substitute the common use of "like" or "love".
- For example, instead of saying, "I really like studying calculus," you could say "I'm keen on studying calculus." You can also use this expression to talk about being interested in people, for example, "She is keen on him."
