Abstract
The manifestation of a tendency towards language economy is expressed in the formation and use of complex words - (quasi) composites. The pragmatic component of the lexical meaning of such neoplasms often contains an emotional and evaluative meaning, which allows the use of such neologisms as a means of self-expression, as well as in the special vocabulary of publicistic texts.
The focus of this study is the international construct eko- (ekologický) in complex words of the Czech language. The paper compares quasi-composites and their functional-semantic equivalents, which are generating phrases.
Semantic groups of neologisms with this component are presented. The analysis is based on the material of the Czech database of neologisms Neomat, the portal of neologisms Čeština 2.0, the Czech National Corpus, as well as search engines.
