This sociolinguistic study describes and analyzes an Israeli Palestinian border village in the Little Triangle and another village artificially divided between Israel and the West Bank, tracing the political transformations that they have undergone, and the accompanying social and cultural changes. These political, social and cultural forces have resulted in distinctive sociolinguistic patterns.The primary explanation offered for the persisting linguistic frontier found in rural Palestinian communities is the continuing social, political, economic and cultural differences between Palestinian villages in Israel, and Palestinian villages in the West Bank. In the geopolitical and economic history of the villages, these distinctions have been maintained by the dissimilar treatment received by the two communities and their inhabitants under Israeli government policy. Exacerbated by the Palestinian Intifada, the relations of the Palestinian divided communities to each other and to the rest of the world have produced noticeable differences in economic, educational and cultural development. The sociolinguistic facts revealed in the language situation in the villages are study shown to be correlated with political and demographic differences.
