Reddit reviews Los sonidos del espanol: Spanish Language Edition

Going off of what others have said regarding finding syllabi, I don't think you'll find an online Introduction to Hispanic/Spanish Linguistics course. As a doctoral student, wouldn't you be comfortable with some introductory texts on the subject?

While I think the materials /u/patricks12345 are good, I don't think they are actually introductory. There are some good (or at least, often used) texts that I've seen/used:

https://www.amazon.com/Spanish-English-Contrasts-Course-Linguistics/dp/0878403817/

https://www.amazon.com/Introducción-Lingüística-Hispánica-Ignacio-Hualde/dp/0521513987/

https://www.amazon.com/Introducción-lingüística-española-Milton-Azevedo/dp/0134840313/

https://www.amazon.com/Introduccion-Linguistica-Espanola-3rd-Spanish/dp/0205647049/

There are also books on specific subfields that can follow up to these, just as normal textbooks do for "basic/general" linguistics.
