These YouTube channels are perfect for learning new phrases and clarifying grammar concepts. They're also a great way to learn about French culture. As they're spoken in French, they're useful for immersion, but do be sure to immerse in other materials - as these videos are usually spoken at a slower pace than normal conversation.
