Abstract
The article concerns Slovak and Polish augmentative derivatives - nouns and adjectives with their word-forming exponents (suffixes and prefixes) and lexical exponents such as adnominals, which specify the meaning of magnitude (augmentative). The author pays attention to the state of research in this area and to the necessity of comparative Slovak-Polish research. The research material has been extracted mainly from Slovak lexicographical sources and the National Corpora of Slovak and Polish languages. The semantic properties of the described units are also the subject of analysis. Moreover, the suffixal and prefixal formants of selected augmentative derivatives are also characterised based on models proposed in the Slovak dictionary of word formation.
