DERIVATION AND LEXICOLOGY. DIACHRONIC VIEW

The paper raises the problem of the status of word formation facts in a comprehensive description of the language. The authoress, referring to a discussion that has been going on for several years concerning the morphological or lexical character of derivates, presents additional arguments showing that word formation should be included in lexicology. The basis of this research are historical and linguistic facts certified in ancient Polish dictionaries. On the example of lexicalization and tautology phenomena present in ancient Polish language she tries to point out the groups of derivate lexemes that should also undergo a lexicological analysis.
