The Dẹgẹma language is not also called "Atala" or "Udekaama", as stated in some publications. Atala is the alternative name for one of the Degema-speaking communities (Degema Town), and Udekaama is the name of a clan (which comprises Usokun-Degema and Degema Town). Similarly, "Dekema" is not an alternative name for the Degema language as contained in the entry for Degema in the Ethnologue.[<span title="This claim needs references to reliable sources.
