Sidaamu-afoo

Sidaama or Sidaamu Afoo is an Afro-Asiatic language, belonging to the Highland East Cushitic branch of the Cushitic family. It is spoken in parts of southern Ethiopia by the Sidama people, particularly in the densely populated Sidama state. Sidaamu Afoo is the ethnic autonym for the language, while Sidaminya is its name in Amharic. Although it is not known to have any specific dialects, it shares over 64% lexical similarity with Alaba-K'abeena, 62% with Kambaata, and 53% with Hadiyya, all of which are other languages spoken in southwestern Ethiopia. The word order is typically SOV. Sidaama has over 100,000 L2 speakers. The literacy rate for L1 speakers is 1%-5%, while for L2 speakers it is 20%. In terms of its writing, Sidaama used an Ethiopic script up until 1993, from which point forward it has used a Latin script.

The term Sidamo has not used by some authors to refer to larger groupings of East Cushitic and even Omotic languages. The languages within this Sidamo grouping contain similar, alternating phonological features. The results from a research study conducted in 1968-1969 concerning mutual intelligibility between different Sidamo languages suggest that Sidaama is more closely related to the Gedeo language, which it shares a border with to the south, than other Sidamo languages. According to the Ethnologue, the two languages share a lexical similarity of 60%. Sidaama vocabulary has been influenced by Ge'ez and Amharic, and has in turn influenced Oromo vocabulary.
