n. pl. dum·ky(-kē) also dum·kas
1. A Slavic folk song that alternates in mood between liveliness and melancholy.
2. An instrumental composition or movement imitative of such a folk song.
[Ultimately (via Czech, since the dumka was popularized as a form in classical music principally by Antonín Dvořák) from Ukrainian dumka, diminutive of duma, thought, memory, melancholy narrative poem or ballad, of Germanic origin; see dhē- in the Appendix of Indo-European roots.]
