[3] After his death in 1992, the Ubykh language went extinct despite the efforts and work of numerous linguists to revive it.

Nevertheless, Esenç is single-handedly responsible for the world's current knowledge of Ubykh language and culture being as extensive and detailed as it is.

Esenç was raised by his Ubykh-speaking grandparents for a time in the village of Hacıosman (Ubykh: Lek'uaşüa /lɜkʷʼɐ́ɕʷɜ/; Adyghe: Hundjahabl) in Turkey, and he served a term as the muhtar (mayor) of that village, before receiving a post in the civil service of Istanbul.

He spoke Turkish and Ubykh, and also a dialect of Adyghe (West Circassian), allowing some comparative work to be done between these two members of the Northwest Caucasian family.

This is where Ubykh comes to an end.Esenç died in the night of 7 October 1992, at the age of 88; he was buried in the village cemetery of Hacıosman, his birthplace, alongside his wife Emine.
