Sign languages are of great interest to linguists because, while they are produced by the same brain, their physical transmission differs greatly from that of spoken languages. Wendy Sandler and Diane Lillo-Martin compare spoken languages with those that are signed, in order to seek universal properties of human languages. No prior background in sign language linguistics is assumed, and numerous pictures are provided to make descriptions accessible to readers. | Sign Language and Linguistic Universals by Wendy Sandler, Hardcover | Indigo Chapters
