The paper constitutes a brief analysis of diminutives appearing in Czech and Polish. The Author’s major point of interest are functions of diminutive terms in folk works and in communication. As far as the communicative functions are concerned, notable are the manifestations of language infantalisation, irony, and familiarity. The quantitative ratio of the investigated forms appears to be comparable in both languages, although recently diminutives have been enjoying a particular popularity in the Polish youth slang.
