Here is the portal [hold on to your seats] of The State Committee on Information and Press of the Republic of South Ossetia. Official news channel of the de facto authorities.

Notice the fact that the town’s name is written Tskhinval, not Tskhinvali. The -i suffix is considered as a Georgian alteration of the original name. As a result, de facto authorities dropped the letter from the names. Sukhumi became Sukhum, etc. Converesely, when I was in Georgia, some Georgians would call me Alexi. Which now makes me feel like a separatist, for dropping the -i ending in my name.
