Abstract
The chapter presents and illustrates examples of the processes of composition, in the creation of adverbs. The composition is applied only sporadically in the creation of adverbs, the juxtaposition is the most common among them.
The concept and classification of compounds in this grammar comes from their word-formation structure, i.e. in terms of functionally structural, not genetic aspect. The proportion of composition in the language expression of the concept, its system character, variability and update modifications are monitored, as evidenced by the occurrences of compounds in the current usage (based on excerpts from the Czech National Corpus).
