Al-Sayyid Bedouin Sign Language
Al-Sayyid Bedouin Sign Language (ABSL) is a village sign language used by about 150 deaf and many hearing members of the al-Sayyid Bedouin tribe in the Negev desert of southern Israel.
As deafness is so frequent (4% of the population is deaf, compared to 0.1% in the United States) and deaf and hearing people share a language, deaf people are not stigmatised in this community, and marriage between deaf and hearing people is common. There is also no Deaf culture or politics.
