Conform means to change or adapt your behavior or way of thinking to fit in with what's considered normal or accepted by others. It can also mean to shape or form something into a particular mold or design.
When you conform, you're often trying to blend in and not stand out from the crowd. For example, if you join a new school and see that most kids like to listen to hip-hop music, you might start listening to it too because it's what everyone else likes. This is conforming, as you're changing your tastes to fit in with others. But being true to yourself can also mean refusing to conform when others try to make you change who you are or what you believe in.
(transitive, intransitive) To adapt to something by more closely matching it, especially something normative.
