@Propatriamori: The language codes are there for a reason. If you were not planning to vandalise the entry, why did you change language codes from Russian (ru) to Slovak (sk)? In your edit in diff you have added the Russian term to Category:Slovak terms inherited from Proto-Slavic and Category:Slovak terms derived from Proto-Slavic and removed from the appropriate Russian categories. --Anatoli T.
