Description:Signed languages are the naturally-evolved visual-gestural languages of deaf communities. The realization that they are true languages is one of the great discoveries of the last thirty years of linguistic research. This book examines the linguistic properties of many, including detailed case studies of Hong Kong, British, Mexican and German signed languages. The contributors focus on determining the extent that linguistic structure is influenced by whether a language is signed or spoken. Their answers contribute to further understanding the organization of languages.
