The subgroups are composed of descent groups and lineages. Often these are called "Deqqi-...", sometimes also "Ad...", after a common ancestor, such as the Deqqi Tesfa of the western lowlands of Seraye or the Ad Deggiyat, a name for the Seazzega dynasty of the Mereb Melash. In addition, there are ancient, more vague group-designations above the level of subgroups, used by elders as identity-markers: Agaziyan (descendants of the Agazi) for the inhabitants of Agame and Akkele Guzay, and Sabawiyan for the people of Aksum and Yeha.
