Bombastic

bɒmˈbæstɪk

adjective

high-sounding but with little meaning; inflated

The word 'bombastic' originated from the Latin word 'bombasticus' meaning 'cotton'. Over time, it evolved to describe language that is overly stuffed or padded with superfluous words or phrases.

He was introduced to Abd el Kader, who, sitting in pomp on the divan, made a bombastic speech, stating that the Sherif now took over Jebel Druse through his agency, and all existing officials were confirmed in their appointments.
