Abstract
Languages differ in many ways, and one of the main criteria is vocabulary. It is not surprising when languages that are not closely or distantly related have different vocabularies. However, when we talk about languages that are closely related, mutual communication becomes possible to a certain extent. It is also interesting to note that even within one language or language variant, there can be variations in vocabulary. Although many words may have the same meaning, they are used on different stylistic levels. Some words in one language or variant may have a broader range of meanings than in another, creating what is known as “false friends” which we often encounter in language schooling. Therefore, it is worth taking a closer look at this topic.
