pomposity
UK: /pɒmˈpɒs.ə.ti/ | US: /pɑːmˈpɑː.sə.ti/
n. the quality of being pompous; excessive self-importance or exaggerated dignity.
The word "pomposity" derives from the Latin "pompa" (meaning "procession" or "display"), which evolved into "pompous" in English, describing someone who displays exaggerated self-importance. The suffix "-osity" (from Latin "-ositas") transforms the adjective "pompous" into a noun denoting the abstract quality of being pompous. The morpheme "pomp" retains its core idea of showiness, while "-osity" generalizes it into a trait.
