The Mesmes language is an extinctWest Gurage language, one of the Ethiopian Semitic languages spoken in Ethiopia. There are still many people who claim the Mesmes ethnic identity, but none who speak the language. The last speaker of the language was interviewed by a language survey team when he was approximately 80 years old. He had not spoken the language for 30 years, having nobody to speak it with when his brother had died.
The Mesmes have shifted to speaking the Hadiyya language. However, they still maintain some cultural distinctives, including their own style of house architecture.
