• The mountains of the Tangale-Waja Uplands are inhabited by a number of small ethnic groups. They speak different languages which belong to two unrelated linguistic stocks. The Afroasiatic stock is represented by Chadic languages, especially Tangale, but also Pero and Kushi (further to the south along the slopes of the Muri Mountains) of the Bole-Tangale Group. But the majority of the languages belong to the Adamawa branch of the Niger-Congo stock. The study of the vocabulary, technical terms and expressions relating to farming in general and 'farming on terraces' in particular constitutes another important aspect of our multidisciplinary research project providing us with valuable information about the history of the settlements and cultures of the entire region. In this communication we will restrict ourselves to a few general observations which are mainly based on the comparison of selected items of the farming vocabularies of those communities which used to farm the slopes of the mountains in our research area. We want to focus on the various designations for "terraced farms" and "terraces" including any arrangement or setting of stones on farms to enhance and support the production of the staple food: guinea corn (sorghum) and/or millet (pennisetum).
