The main objective of this study is to provide criteria for the delimitation of lexicalized instrumental manner adverbs in Polish. The ADV(Instr) figés have to be distinguished from the typical instrumentally-marked phrases and the syntactic complements of the verb, both in idiomatic and in ordinary sentences, in which they appear also in the Instrumental case. Objects, instrumental adjuncts and lexicalized instrumental manner adverbs will overlap with the usual nomenclature of semantic roles : objects, tools and manners. We will examin the criteria for the distinction between these concepts.
