rimbombante
pompous
Origin: From rimbombar (to resound, to boom), itself from Italian rimbombare.
Also means
high-sounding
Usage Note
Rimbombante describes language, titles, or claims that sound grand and impressive but often lack substance — the Spanish equivalent of 'high-flown' or 'bombastic'. It is almost always pejorative: un título rimbombante (a pompous title), palabras rimbombantes (flowery, empty words). It is purely a quality adjective and does not describe sounds literally, despite its onomatopoeic origin.
Examples
"Usó palabras rimbombantes para ocultar su ignorancia."
Natural Translation
He used pompous words to hide his ignorance.
