The term terminology in modern linguistics is used in different meanings. In accordance with the structure of this term (it is a combination of the word the term and the Greek logos - the word, the doctrine), it denotes the doctrine of terms, the section of linguistics (lexicology) dealing with the study of terms , or the corresponding scientific (scientific and applied) discipline. However, in this sense, the term is rarely used. In recent times, some linguists have used the term "terminology" to describe this concept.
