You can find out a lot more about language on my YouTube channel. The videos are meant for university students, but I try to design them in such a way that they are accessible to everyone. Here, I just highlight three videos that my viewers have found particularly useful: 1. If you're interested in dialects, you will like this video on sociolinguistics, which expands on the topics that were covered in this Ted-Ed lesson. 2. I created a series of videos on varieties of English around the world. 3. More generally, if you are interested in linguistics and you are thinking about studying it at university, there is a video with a few thoughts on that here.
