The Sio counting system is a base-five system which has an element of body part counting. The numbers up to and including five, the 10 and 20, each have a unique name. All other numbers represent combinations of these terms, with the word “kanaŋo” linking the terms. Outside of the counting system, this word is a noun that means “fruit” or “product of”, so within the numbering system it can be roughly translated as “produces”.

It should be emphasized that this original numbering system is rapidly being replaced by the English system. The original numbers are likely to be used up through 10, and may be used up to 20; but beyond this point, only a few older speakers retain the original counting system.
