The book explores the change over time in language-society relations in a multilingual periphery of Egypt. Based on extensive fieldwork and interviews, it is the first of its kind to portray the inventory of linguistic and accompanying non-linguistic behaviors observed within and between different ethnolinguistic groups in the Siwa Oasis. It provides first-hand information about the linguistic habits of Siwan women, an aspect which is generally difficult to access in this gender-segregated community. The book sheds light on Berber-Arabic contact at the core of the Arab world and at a critical time when individual linguistic repertoires are expanding and Arabic is emerging as a powerful resource.
