What kind of materials are out there to learn ASL?
There are all kinds of materials. The most prominent are the sign language books, which have loads of vocabulary mixed with a summary of what Deaf Culture is all about. Some have small sections saying that ASL is nothing like English, but don’t really tell you how it’s different. But there are books out there for grammar! One I use is American Sign Language Phrase Book by Lou Fant. It shows many basic phrases which are used in everyday language. I will be updating my Basic Books section soon to include the many dictionary and phrase books out there.
