Proto-Slavic

Alternative reconstructions

*kǫbъ (per Vasmer)

Etymology

Attested mainly in Northern Slavic, except perhaps for dial. Macedonian куб (kub, “small shape, vessel”), Bulgarian кубица (kubica, “type of gadget or toy”). No certain relatives outside of Slavic:

Per Vasmer: Possibly related to Sanskrit कुम्भ (kumbha, “pot”), Avestan 𐬑𐬎𐬨𐬠𐬀 (xumba, “pot”) or Ancient Greek κύμβος (kúmbos, “vessel”), implying a nasal reflex (as if from *kǫbъ).^[1]
Per Trubačev: Without nasalization, as evident by Polish kubek, Lower Sorbian kub. Possibly akin to Lithuanian kaũbras (“mound”), Phrygian Κύβελον (Kúbelon, “mountain in West Anatolia”), perhaps from Proto-Indo-European *kewbʰ- (“to arch, to bow”).^[2] Potentially part of a large complex of ambiguously-resolved words including Ancient Greek κῡφός (kūphós, “stooped”), Latin cubō (“to recline”).
