everyone, everybody, nobody is or are?

Hi, welcome to my channel! In this lesson, you will learn about everyone, everybody, and anybody.

A short introduction about myself:
My name is WY (Wy Yee) I am an ESL instructor and I have created this channel so that people from all around the world can learn English remotely. It began when the whole world was in a state of lockdown and many students and instructors have resorted to teaching online. I hope my video lessons will be able to help students from all around the world.
