He doesn't have too many languages to offer, because of resources and lack thereof, as well as costs and finding people he can use, but what he does have... is fucking great if you want to learn, say, Greek, Italian, German, and a couple others. But by far, his best course he offers is Spanish.
It is a complete, as the title suggests in playlist, course. That does NOT teach you the redundant bullshit crap of structure and needless sentences, conjugations, etc., that every other channel and website teaches you, but he does what I love doing, and that makes it even the more enjoyable, and that is breaking down words in another language or even English, and "transferring" the meaning over to the target language. He makes it very simple and very easy to learn these things.
He explains in his book, that every language is basically just a dialect of another language. The amazing thing about learning (almost) any language is that we already know thousands, not dozens nor even hundreds of words but thousands! All that has to be done is to change a few things through a pattern for the respective word type, and you've just "transferred" the word over to that language.
He will show you just how easy it is to learn a language.
Anyways, enough of my talking, lol If you're interested, check it out below.
