köken: Uncertain. Various theories exist. One ties it to Late Latin *ballizāre, from Ancient Greek βαλλίζω (ballízō). Another derives it from Late Latin balteāre, from baltea, from Latin balteus (“belt”).
vault · the string worn by the followers of Zoroaster
köken: Reborrowed from Aramaic קמרא (qamrā) / Classical Syriac ܩܡܪܐ (qamrā, “girdle”) – in spite of the sense "vault" not being attested in Aramaic, and notwithstanding the sound correspondence /q/ → /k/, which is like in کما (komâ, kamâ) –, itself from Middle Persian 𐭪𐭬𐭫𐭩 (kmly /kamar/, “girdle”), 𐫞𐫖𐫡 (qmr /kamar/, “vault”), the progenitor of کمر (kamar, “belt, arch”).
köken: From Persian گنبد (gonbad). Cognate with Bashkir көмбәҙ (kömbəź), Nogai куьмбез (kümbez), Kyrgyz күмбөз (kümböz), Uzbek gumbaz, Turkish kümbet, etc.
köken: From earlier abóbeda, from Old Galician-Portuguese boveda, possibly from the hypothetical Vulgar Latin word *volvita, alteration of Latin volūta, from volvere (“to turn”), but this presents serious phonetic difficulties. Compare Spanish and Galician bóveda. More likely of Germanic origin, from a Gothic *𐌱𐌿𐍅𐌹𐌸𐌰 (*buwiþa), from a derivative of Proto-Germanic *būaną (“to dwell reside, build”).
shop (GB), store (US) (especially applied to relatively small shops in the countryside) · synonym of élelmiszerbolt, közért (“grocery store”). · deal (a particular instance of trading [buying or selling; exchanging; bartering]; a transaction)
Probably akin to Latin fornāx and furnus, fornus (“furnace”), and derived from the latter as *fornikos (“vaulted like a furnace”): typologically compare Ancient Greek κάμινος (káminos, “furnace”) beside καμάρα (kamára, “vaulted chamber”), both possibly from Proto-Indo-European *kh₂em- (“to bend, to curve”).
