There are a number of other sign languages in towns and villages in Israel, in which we have conducted preliminary research:  Abu-Kaf, Al-Atrash, Arab El-Naim and Ein Mahel.
As signs from Israeli Sign Language are used in the education system, and as village signers have more contact with ISL signers through social and sports activities, it is not yet known whether this will result in marginal lexical borrowing, in creolization of village sign languages, or in their extinction over time.
