She’s a teacher at a Spanish school (that is, a school for foreigners that teaches Spanish) in Madrid. She’s a native speaker (unlike Señor Jordan), and obviously the Spanish she teaches is the Iberian dialect, specifically that from Madrid. What I like about her is that she not only speaks slowly and clearly, and provides Spanish subtitles for all her videos, but especially that she makes most of her videos out of lessons with actual students. That is, you learn a concept along with the student she’s teaching who is also learning it, that way the tempo of the instruction is matched to that of such a student, plus they tend to ask the same questions and have the same problems that you likely will have.

Check out her video about tan/tanto to see what I mean:

Yes, the dictionary. They have their own YouTube channel where they’ve put a lot of fairly high-quality content, mostly about various grammar concepts and common phrases. I will warn you that most of their videos are fairly old and as such the audio and video quality is not so great, but the explanations are pretty good. The below video illustrates this (yeah, that’s 240p):

These are much more recent/modern, and very well-made. God does she love her whiteboard, though (not criticizing). She’s a native speaker, Latin American, though I’m not sure from which country. She’s covered a ton of topics already, explains things slowly and comprehensively, and does so mostly in English (though I notice that subtitles are provided for when she speaks Spanish! excellent!). Check out this video on describing how you feel in Spanish:

He’s a native English speaker living in (I believe) Spain at the moment. He makes fairly long videos (30-45mins) explaining various Spanish concepts, principally using very simple, Powerpoint-like graphics. He does a good job of explaining things though and people seem to think he’s a very good teacher. See his explanation of the preterite tense in Spanish below for an example:

Yes, the professional podcasting company. For what it’s worth, by the way, I think their podcast lessons are excellent and it’s absolutely worth the money to get a membership.

They tend to focus more on how to say various common phrases, expressions, how to talk about certain subjects and events (New Years, your birthday, vegetables, vehicles, “kitchen vocabulary”, etc.), than grammar – if you’re looking for YouTube Spanish lessons for beginners this is an excellent choice. This is what some people prefer so it’s a nice change from most of the rest that do largely focus on grammar. Check out their video below on fruit to see what I mean:

I’ve just spent nearly an hour watching this guy’s videos and I’m pretty impressed overall, but I will add the significant forewarning that his style definitely will not suit some people: it’s very grammar-oriented and he presumes that you already know all the relevant grammatical terminology that he uses (e.g. “dependent clause”, “relative pronoun”, “modal verb”, “imperfect tense”, etc.).

Other than that, I must say that he does an excellent and thorough job of explaining the concepts that he does. His videos tend to be long (20-40 minutes) but given what they’re about that’s a good thing, even a necessary one I would say. The concepts he discusses are complex and cover a lot of ground, they need time and plenty of examples to be explained properly. When you finish one of his videos you’ll feel like you not only have a good understanding of the topic discussed but also like it’s had a chance to sink in fairly well, not like it wasn’t just crammed down your throat as quickly as possible.

Check out his video below about the differences between aquí, acá, allí, and allá for an excellent example of what I’m talking about: it’s thirty minutes long but is probably the best video you can find online about this topic.

This is one of those series like Destinos or Extr@ that’s formulated to help people learn Spanish, so they speak slowly and clearly and at a level slightly below what adults normally would. They do seem to offer a transcription they’ll email you, but they want a small donation for it. Have a look at the first episode:

This is a channel run by a Colombian lady who operates a Spanish school specifically for intermediate and advanced students. The videos are very well done with explanations in English, e.g. the following about Colombian slang:
