The paper focuses on the scope of application of univerbation in new compounds and quasicompounds formation in Czech. The analysis is based on the comparison of parallel occurrence of multiple-word and one-word names (fotopapír - fotografický papír, profiarmáda - profesionální armáda) in representative corpora of (he Czech National Corpus.
The usage of multi-word names, potentially motivated one-word names, in the interpretation of semantics in monolingual (neological) dictionaries is considered a supportive criterion to evaluate analysed names as possible results of univerbation. The aim of the paper is also to assess (quasi)compound formation in terms of pattern (model) formation.
