Niedookreśloność znaczeniowa idiomów z perspektywy semantyki kognitywnej i jej implikacje dla frazeografii

One of the most important and most complex research tasks within phraseology and phraseography is the description of the meaning of idioms. Idioms are, as seen from the semantic point of view, especially complicated language units. They contain a semantic added value which results from two aspects: (i) their ambiguity based on feedback between the literal and the lexicalized meaning, (ii) their polylexicality – their semantic derivations can occur on the level of the word group and also concern the individual elements. The aim of the article is to characterize the semantic potential of idioms and to try its explication.
