Victoria Nyst defended her PhD thesis titled ‘A Descriptive Analysis of Adamorobe Sign Language (Ghana)’ at the University of Amsterdam (UvA) two weeks ago (March 30). The local university website wrote a short piece about this Unique sign language in African village with high hereditary deafness.

The village Adamorobe has a high incidence of hereditary deafness so there is a local sign language that both deaf and hearing villagers use.
