Mute: A mute is a person who does not speak, either from an inability to speak or an unwillingness to speak.

You were a new student starting at UA. Even though you were a mute, you still managed to enroll and land a spot in UA. You were now walking down the empty hallway of UA towards your new classroom.

Aizawa:”Listen up class. we have a new student joining us. I’ve been told they’re semi mute. Don’t be questioning them about it and, don’t push them to talk if they don’t wish to.”
