Hi, Cathy. I see that my brain's wires must have been crossed when I sent my last message. There, I mentioned Búscalo, whereas in my initial recommendation I talked about *English Grammar for Students of Spanish*. Duh. :oops: Perhaps I'll go back and change the message mentioning Búscalo. Though I own and love *Búscalo: A Quick Reference Guide to Spanish Grammar and Usage*, your first message makes me think that you need a book that explains _English_ grammar in more detail than Búscalo does. That's why I recommended *English Grammar for Students of Spanish*. But I can't tell you anything more about it, since I've never used it. I've known people who like it a lot, and it gets very good reviews on Amazon, so I thought I'd let you know about it, since it seems as if it would be very helpful to you. I suspect that you could use it more or less like a dictionary or encyclopedia, just looking up and reading about the grammar terms you want to understand. You can get a little idea of what it's like by clicking on the "Look Inside the Book" feature in its listing on Amazon.com.
At some point, you may decide that you also want Búscalo. It offers lots of clear, concise information about Spanish grammar. I use it a lot. However, though Búscalo does not throw a lot of technical jargon at you, I think you need to know English grammar a little better than you do now to make the best use of it.
I hope this helps.
