An assistant language teacher is someone who helps people learn a new language. For example, if you are learning how to speak French, an assistant language teacher might come to your school and help teach you. They might help you with pronunciation, grammar, and vocabulary. They might also help you with things like reading and writing in the language. They are like a helper that is there to make learning a new language easier and more fun. They might even be from a different country and speak the language you are learning as their first language!
