The scope of the present article is a synchronic description of the word-formation process concerning verbal derivations in which the non-inflectional part of the word-forming base has been truncated. The study covered 400 verbal formations motivated by nouns and adjectives. The analysis led the authoress to the conclusion that adjectival formations dominate among the derivations of de-nominal verbs (60% of the de-nominal derivations). Among the de-adjectival derivations, 12 are truncated, while among de-nominal derivations as many as 24. At the centre of verbal de-nominal derivations lie reductive derivations, prefixal-reductive ones, as well as reductive-suffixal ones. Reductive de-nominal verbs are mostly mutational derivations. In approximately 90% of verbs the formatives have an objective semantic function.
