The numeral system of Ikaan, a Benue-Congo language of Nigeria

"This study provides a comprehensive description of the Ikaan numeral system, based on data collected in Ikakumo where Ikaan is spoken. There are two major domains of investigation. First, the formation patterns of Ikaan numerals are investigated, detailing how, in the base '20' system of Ikaan, addition, multiplication and subtraction form higher numerals and which rules underlie these formation processes. Second, the diversity of the morphosyntax of Ikaan numerals is explored, determining the various parts of speech involved in Ikaan numerals and the way in which numerals interact with other constituents in a phrase. Additionally, the study aims to provide a holistic documentation of Ikaan numerals, describing their use in the speech community as well as their accompanying counting gestures. The structure of ordinals and distributives is also covered"--Page 4 of cover.
