The Arbore language is classified as a member of the Omo-Tana group within Lowland East Cushitic, together with Daasanach, Elmolo, Bayso, Rendille, Boni and the various Somali dialects.

[1] The people who also call themselves the Hor (Hoor) live in four villages in the delta of the Limo River (also known as Dullay or Weito) at the northern end of Lake Stephanie (Bau or Chew Bahr) in South Omo Zone.

[6] The Arbore practice pastoralism, sorghum cultivation, seasonal fishing and hunting and engage in a wide regional network of bond friendship for the exchange of gifts.

Each generation class (herr) comes to power after an initiation which is held once in about 40 years in rituals known as ner and chirnan.

Both the Arbore and their neighbors enter the sacred cattle-gates of qawots (ritual chiefs) with gifts of heifers, bulls, honey, coffee, tobacco and herbs to receive blessings for human, animal and crop fertility, for rain and for victory against their enemies.
