The article focusses on derivation and compounding processes in Kambaata (Cushitic) that have cardinal numerals as input. After the formation of cardinal numerals has been summarised, the contribution decribes in detail the ordinal, distributive and multiplicative numeral derivations. Furthermore, one section of the paper is dedicated to adjectival and nominal compounds based on numerals. Finally, the article elaborates on the expression of fractions, approximation and mathematical operations. Whenever possible, denumeral formation in Kambaata is compared to that of the closely related Highland East Cushitic languages.
