ABSTRACT
Deaf people have gathered to use sign language over the millennia, and where there have been deaf people, there have been sign languages. There are records of deaf people in antiquity from Greek, Roman, and Jewish writings (Woll & Adam, 2012; Woll & Ladd, 2003), and deaf people have been philosophised and written about ever since. It follows also that where there are deaf people, sign languages have arisen, and where there are sign languages, there has been a need for sign language interpreting, sign language translation, language brokering, and sign language intervention between language communities, whether spoken or signed.
