Iść w trupa – o jednym ze źródeł współczesnej polskiej frazeologii

This article deals with modern Polish phraseology and one of the sources of its enrichment. The author discusses the motivation behind the idiom iść w trupa – in sports jargon ‘to fight hard, regardless of risk to the body’, literally ‘to go into the corpse’ (according to the degrees of motivation described by Andrzej Maria Lewicki). While the phrase comes from the language of sport, it has acquired a new meaning in colloquial language. In the article, the idiom’s semantic features in the sociolect and the colloquial Polish are discussed. The second part of the paper presents a few general remarks on sporting phraseology.
