Abstract
Czechoslovak Republic underwent huge political changes in 1989. The period of communist totalitarian rule ended (1948 - 1989) and the country returned to democracy.
This paper attempts to show how language changed with the change of political discourse. The intention od the dictionary is to preserve the vocabulary of the period for the younger generation; also to remind the older generation of vocabulary that they used to encounter, but are gradually forgetting.
The dictionary is specific in that it is made up of two types of vocabulary - the language of communist propaganda and the spoken language emerging from how people reacted to the pressure of propaganda, often including popular humour. The first type of vocabulary has been collated through Corpus of Totalitarianism, for the second type a corpus-based source does not exist (it is the language as spoken, which it was possible to collate through quotes from fiction, journalistic writings and from the author's own observations).
We have to bear in mind that totalitarian language (""language of the rulers"") and unofficial language changed its character over time.
