From earlier abóbeda, from Old 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 bóveda. More likely of Germanic origin, from a Gothic *buwitha, from a derivative of Proto-Germanic *būaną (“to dwell reside, build”).
abóbada f (plural abóbadas)
- (architecture) vault (arched ceiling)
