[3] The people live on the Nkambe Plateau, a dramatic grassy highland cut by wooded ravines, about a mile above sea level.
[5] Most are farmers, growing maize, beans, potatoes, yams, vegetable, tomatoes, bananas, and also plantains and coffee in lower, warmer areas.
The three dialects cut across the three clans, and may result from influence of the neighboring languages to the north and south.
[8] Limbum is closely related to some neighboring languages like Yamba and more geographically distant ones like Bamum, Ngemba and Bamileke.
