The artistic practice of Mladen Stilinović, one of the founders and the liveliest protagonists of conceptual art in Croatia and the region, may be presented by using the key words, i.e. words that introduce the core problem and the procedures that the artist uses: language, ideology, manipulation, appropriation, correction, irony, installation, de-contextualization, exploitation, repetition, tautology. In Stilinović’s well-known Dictionary–Pain (2000–2003) have been crossed out white and changed into one and the same word of unique meaning—pain—in a potential “imperatival dictionary” some words could easily change places and the structure without the change of meaning.
