Up to now, the etymology of Common-Slavonic *sъtъ ‘honeycomb’ is not explained sufficiently and it remains uncertain. The author of the paper discusses various existing explanations of the word, and proposes a new solution according to which the word belongs to the originally onomatopoeic root *sъp- ‘to hum, to drone’. This root is only a variant of a larger onomatopoeic set of forms that served to express different secondary meanings of the original meaning ‘to gasp, to pant, to breathe loudly, hard’ (*sop-, *sap-, *sip-, *sěp-, *sup-).
