A tutor is a person who helps you learn new things, just like your teacher at school. Think of it like having your own personal teacher who gives you extra help with your homework or any subjects you find difficult.
When you have a tutor, they will sit with you and guide you through your homework, they will explain things to you in an easy and understandable way, and they will help you improve your skills.
It's like having a friend who is really really good at the subject you're struggling with, who can explain things to you in a way that makes sense to you.
So, if you ever need help with your schoolwork, you can ask your parents to get you a tutor who will work with you to help you understand and succeed in your studies.
