Dime is an endangered South Omotic language. The major researches done on Dime are Fleming (1990) and Mulugeta Seyoum (2014c, 2013b, 2012, 2011, 2010a, 2009a-b, 2008a-d, 2007a-b, 2005, 1997). The former dealt with a survey of Dime grammar, while the later work focused on extensive descriptions of phonology, morphology and syntax. Dime people are declining through time due to diseases, hunger and war according to Fleming (1990). The other factor is bilingualism. Except a few numbers of monolingual Dime speaker most of them speaks one or more neighboring languages next to their mother tongue. Their positive attitude to learn another languages rather than learning Dime activates their language endangerment. This may be due to economical or political reasons. Because of wealth resource conflict with the neighboring communities a lot of Dime migrated. They have some cultural affinities with the neighboring ethnic groups. For instance, their musical instruments resemble with other Omotic people such as the Aari.
