Semantic derivation and semantic word formation are closely related concepts that reflect different functions in the formation of a semantic system. Semantic derivation characterizes lexical-semantic processes in a language, and semantic word formation is typical of grammatical semantic processes. Semantic derivation is a quantitative factor of semantic changes since the emerging new connotations of words increase their semantic scope. First of all, this is a phenomenon of speech, not a language, because the actualization of different connotations of words depends on the context in which the unit of language is used. Thus, the text plays an important role in the functioning of semantically filled elements (syncretes). The text describes the meaning of the word.
