his article completes the intermediate stage in a series of publications by the authors on the topic of the origin of the ethnonyms “Alans” and “Albans” and the corresponding polytonyms “Alania” and “Albania’, the toponyms “Alan and Albanian gates”, "Al-burz”, "Elbrus". The accumulated new data are well-corresponding to the interpretation proposed by the authors in previous articles. In some cases, there are trivial explanations basing on the original semantics of the Caucasian root with the meaning 'king, prince, ruler'. Traces of the original meaning are found in the manuscripts of Armenian chroniclers when they try to interpret the source of the name of Caucasian Albania. Also the original meaning is truly seen in epithets characterizing famous aristocratic surnames. The folklore material of the Ossetian epic Nart Saga is also significant. There were found several toponyms in Kakheti which have a direct connection with the topic of this article. The Arab geographer al-Mas’udi gives an extended description of the meaning of the Ossetian derivative from the name 'king, prince'. The dominant peaks on the terrain, as well as significant passages called "gates" gain the epithet composits "King-Mountain" and "King's Gates". The article is of interest to linguists, historians and ethnographers and it allows to exclude unnecessary ethnic correlation of specific toponyms and epithets in many concrete cases.
