Langfocus is a YouTube channel where a polyglot details the history of various languages, how they work, and a few reviews of products. He mixes a small blend of humor but mostly focuses on education content. He is a polyglot as well, being an expat currently living in Japan.

SleepyPolyglot:
 * Whenever I start learning about a language, I will normally go to LangFocus first so I can get a good grasp of what I am dealing with, as it talks quite a bit on the origins, spread of the language, and the basics of the grammar system. He is really informative.  I have seen small complaints about the voices that he uses for his video, especially in the comments sections, but, as he has grown the series, the complaints are a lot less, and his videos have become quite numerous. 9/10
