阿达莫罗贝手语

Adamorobe Sign Language or AdaSL is a village sign language used in Adamorobe, an Akan village in eastern Ghana. It is used by about 30 deaf and 1370 hearing people (2003).

Under these circumstances, AdaSL has developed as an indigenous sign language, fully independent from the country's standard Ghanaian Sign Language (which is related to American Sign Language). AdaSL is a shared sign language which differs from urban sign languages such as Ghanaian Sign Language because the majority of speakers of a shared sign language aren't actually deaf. National sign languages usually emerge for the purpose of use by deaf individuals such as those attending schools specifically for the deaf. This important feature of shared sign languages alters the way it is maintained, developed, and shared. A historical example of a shared signing community is the island Martha's Vineyard (Martha's Vineyard Sign Language).

For over a decade, the deaf children of the village have attended a boarding school in Mampong-Akuapem, where the ASL based Ghanaian Sign Language is used. As a consequence, this language has become the first language of these children and their command of AdaSL is decreasing. This is likely to lead to a complete shift of the deaf community in Adamorobe to Ghanaian Sign Language. As such, AdaSL is an endangered sign language.
