Usage notes

• The suffix is added to the stem of the word (i.e. minus its final vowel, if any). An epenthetic vowel often breaks up stem-final consonant clusters, and velars become palatals according to the Slavic first palatalization (both effects are due to the yer that occurred at the Proto-Slavic level). These effects can be seen in серде́чко (serdéčko, “small heart”), derived from се́рдце (sérdce, “heart”), and тихо́нечко (tixónečko, “very quiet”), derived from тихо́нько (tixónʹko, “quiet”), itself containing the same diminutive ending. (Specifically, starting from the stem *тихо́ньк-, a vowel is epenthesized, producing тихо́нек-, and the final velar is palatalized, producing тихо́неч-.) In general, the combination -ко + -ко produces -ечко (-ečko) or -очко (-očko).
