The paper deals with word forms occurring in the SYN corpus (1.2 billion words) only once, twice or three times, the so-called hapax legomena, which provide a basis for the study of potentiality in language. As the material was very large, only 20 samples were chosen, each containing 3 000 forms, i. e. 60 000 forms overall. Approximately 50 % of word forms were various mistakes, especially typing errors, or words from other languages. Therefore only the remaining 30 000 word forms were selected as the basis for this study. The analysis showed that the most relevant suffixes for hapax legomena are -ovský (e. g. jimmyreedovský), -ák (e. g. medvěďák), -ista (e. g. havlista), -ing/-ink (e. g. gardening, dancink), -ovitý (e. g. kladivovitý), type po vojensku, diminutives derived from abstracts (e.g. minulůstka) and names of women professions (e. g. meduprodavačka). Moreover, compound words with the first parts dlouho- (e. g. dlouhorožec), gala- (e. g. galamenu), jino- (e. g. jinomluva), kino- (e. g. kinofajnšmekr), mega- (e. g. megakatastrofa), nízko- (e. g. nízkohlučný), polo- (e. g. poločitelný), video- (e. g. videokomentář) were typical for new words.
The article presents a survey of the word-formation means used for the derivation of titles of documents. The focus is placed on the relationship between the semantic motivation and formal founding. The text tries to capture the extent of analogy of word-formation processes on the background of the relationship of langue and parole.
