In the “corpus age” of linguistics, the research in productivity in word-formation has focused on development of measures that enable to calculate productivity from frequency data gained from large corpora. In the contribution, we determine productivity of four suffixes that are used in names of qualities in Czech.
The results obtained by respected productivity measures are compared with a tentative approach (inspired esp. by Dokulil, 1962) to determine productivity of the suffixes on the basis of their systemic features. The disparity of results based on quantitative data vs. systemic features are interpreted in favor of combining both aspects.
