The author focuses on the description of neologisms warranted by proper names, functioning as deproprial words or expressions. On this basis she tries to prove that deproprial way of creating new words in the Czech language is a very productive and frequent derivational process. The analyzed material comes from everyday newspapers and comprise neologisms created from the proper names of politicians. The author also tries to follow what happens with them in the field of language and how they spread in the lexical store of the Czech language. The author divides the material into thematic groups, in which she distinguishes formal subgroups (nouns, adjectives, adverbs). She pays attention to the increased use of prefixes and the creativity of those who invent neologisms (verb formations improper from the point of view of word formation rules), which she believes are the general tendencies in the development of modern Czech.
