Abstract. The article discusses that the methods of conducting toponymic research in the field depend on the conditions of a multilingual environment, which are very diverse. There are countries where the majority of the population speaks one language and understands one language, although some of the population may speak other languages. There are also countries whose population consists of numerous cultural groups speaking different languages. In such cases, standardization programs are based on the principle of focusing on local variants, then most countries have to take into account the approach that takes into account the existence of names in different languages.
