"The Spanish Acquisition: An Underground Grammar," by Tom Lathrop
The Spanish Aquisition is a play on “The Spanish Inquisition.” It has nothing to do with that institution, of course, and it also has nothing to do per se with acquiring language. Its purpose is to help make grammatical concepts easy for students to learn so that acquisition can come more easily. You are not going to be subjected here to simplified falsifications about the language, but rather how these concepts really work, and how easy they truly are.
