Arabic and Judeo-Arabic were widely spoken among Algerian Jewish communities, although usage varied by region, generation and social setting. During the colonial period, French became increasingly prominent, especially in northern cities and formal education. In some regions there were Berber-language connections, including Judeo-Berber speech. Hebrew remained the language of prayer and study.
Daily life turned on religious observance, family ritual and the calendar, and on work: crafts such as metalwork and tailoring, commerce large and small, and the community institutions that ran schools, charity and burial. In cities such as Constantine, Jewish and Muslim musicians took part together in the same Arabic musical traditions, including Arabo-Andalusian repertoire and popular urban song.
Relations between Jewish and Muslim Algerians were neither uniformly harmonious nor uniformly hostile. They varied by city, by period and by circumstance, and colonial policy would later change them substantially.
