The paper presents the results of the analysis of the following lexical units with the word wystarczy : coś a wystarczylo, zeby p ; coś a wystarczylo do tego, zeby p ; coś a wystarczylo komuś n do czegoś b ; wystarczylo, ze q, a p . On the basis of the analysis of their valency and the conducted tests, the author states that all these lexical items imply that an event/a state of affairs caused another event/state of affairs and that someone, basing on their knowledge about the world, could think that this would not have happened. Further research has proven that two of those lexical units – coś a wystarczylo komuś n do czegoś b and coś a wystarczylo do tego, zeby p – imply, moreover, that an event/a state of affairs, caused by another event/state of affairs, was somehow desired. It has also turned out that the speaker using coś a wystarczylo komuś n do czegoś b or wystarczylo, ze q, a p , informs that the resultant event/state of affairs occurred right after the causative event/state of affairs.
