Out of concern for language ‘purity’ ‘Polonizing’ dictionaries/dictionaries of Polish equivalents were published in Poland, whose authors (language purists) aimed to replace words/expressions of foreign origin with native-language equivalents (or with assimilated loanwords). Besides Latinisms or Gallicisms under criticism were also German loanwords. The main focus of the paper is on the pre-sentation of the dictionary by E.S. Kortowicz (1891), in which the author seeks to eliminate Germanisms from the Polish language.
