Verbs + -ing
After some verbs like "enjoy", "don't mind", "avoid", "deny", "finish" etc., if there is a second verb, it takes the "-ing" form. In other words, the second verb is a gerund.
I enjoy playing football.

For special spelling rules when adding '-ing' to a verb, refer to the Present Continuous (A1 - A2) section on this website, where these rules are explained in detail.
