Etymology
Origin of ostentatious
First recorded in 1650–60; ostentat(ion) + -ious
Explanation
Reach for the adjective ostentatious when you want a flashy way to say — well, "flashy" or "showy." No one wants to be described as ostentatious, a word whose cousins include pretentious, flamboyant, and gaudy. It originates from the Latin word ostentare, "to display," but in English it's often used for displays of the crass or vulgar sort. A rapper's diamond-encrusted teeth might be an ostentatious display of "bling," and someone wailing especially loudly at a funeral of a distant acquaintance might be making an ostentatious show of sorrow.
