Linguistics is the scientific study of language

The term lexicology is of Greek origin (from lexis ‘word’ and logos ‘learning, science’). Lexicology is the part of linguistics dealing with the vocabulary of the language and the properties of words as the main units of language. In other words, its basic task is a study and systematic description of vocabulary in respect to its origin, development, meaning and current use. The term vocabulary is used to denote the sуstem formed by the sum total of all the words and word equivalents that the language possesses. By word-equivalents we are going to mean morphemes, word-combinations and phraseological units.
