If you’d like some exposure to what linguistics is, and what kind of research linguists do, there’s a free course on Coursera that you can check out. (But if you want a “Verified Certificate” that you took the course, you have to pay $49.)
Here’s more info about it, over on Language Log. This is actually a better slate of info than the average lecture class, albeit it’s a bit harder to ask questions.
It does feature a short guest interview appearance by the dreaded Noam Chomsky, but hey, they promise that he actually talks about linguistics for once!
The course started yesterday, so you’ve only got one video class to catch up on.
Leiden University is a darned good school over in the Netherlands, but the class is in English.
