The aim of this paper is to review the classification of the southern Moroccan dialects, advancing on the general description of these varieties. Recent descriptive studies provided us with new sources on the linguistic reality of southern Morocco, shedding light on the status of dialects commonly classified as Bedouin or ‘Hilāli’ within the Maghrebi context. To do so, the paper highlights conservative and innovative features which characterize the dialects of the area, focusing mainly—but not exclusively—on the updated data for two distant localities in southern Morocco: Essaouira and its rural outskirts—the Chiadma territory (Aquermoud and Sīdi Īsḥāq)—and Tafilalt, in south-eastern Morocco. The southern dialects have been situated in an intermediary zone between pre-Hilāli and Hilāli categories for a long time. Discussing their situation may contribute to understanding what distinguishes them as a dialectal group and also the validity of the ‘Hilāli’ category in the Moroccan context.
