From 1500 gathered oikonyms in Dysna region about 100 (6.6%) place names are of Lithuanian origin. In reality there are more of them: part of them became more Slavonic, they were translated so it is more difficult to recognize them. In the areas nearer to the Republic of Lithuania and Breslav there are more Lithuanianisms, e.g. in the parish of Ikazne (District of Teterkovka) and among the names of present villages the Lithuanianisms make a quarter (25%) more: Aukslys (Uklia), Bijeikiai (Bijeiki), Dervaniskiai (Dervanishki), Kamsa (Kumsha), Kliausai (Kliavsy), Pasiutiskes (Posiutishki), Pazardziai (Pozhardje), Petkunai (Petkuny), Sparunai (Sporuny), Sakalyne (Shokoleushchina), Siaulenai (Shauliany), Varai (Vary), etc. According to the data of the visitation of Breslav deanery there was written in Polish that there were in Druja these clearer oikonyms of Lithuanian origin: Arshele 'Arseliai', Druja, Jaja 'Jauja', Jodkovshchyna 'Juodkyne', Obolonie, Poviacie 'Paviete', Pupinovo, Pushkele 'Puskeliai', Raksniovo, Rovbie 'Raubiai', Stashule 'Staciuliai', Svilkovo, Shalcinovo, Sharkele 'Sarkeliai', Vaise 'Vaisiai', Viata 'Vieta', Zubry 'Zubrai'.
