Related Words
Grandiose, showy, ostentatious, pretentious all refer to conspicuous outward display, either designed to attract attention or likely to do so. Grandiose and showy are alike in that they may suggest impressiveness that is not objectionable: the grandiose sweep of the arch; a fresh bouquet of showy zinnias. Grandiose, however, most often implies inflation or exaggeration to the point of absurdity: grandiose, impractical plans; a ridiculously grandiose manner. Showy sometimes suggests a meretricious gaudiness or flashiness: a showy taste in dress. Ostentatious, which refers to behavior or manner clearly designed to impress, also has negative connotations: an ostentatious display of wealth; an assumption of superiority too ostentatious to be ignored. Pretentious, like the preceding term, is always derogatory, implying falseness or exaggeration in claims made or implied: natural and straightforward, not pretentious; pretentious language designed to mask the absence of real content.

Etymology
Origin of grandiose
First recorded in 1830–40; from French, from Italian grandioso, from Latin grandi(s) “grand” + -ōsus adjective suffix ( see -ose 1)
Explanation
You've got big plans. Huge plans. Whatever it is, it's going to blow minds and absolutely rock worlds! Well, to some people those plans might sound a bit grandiose, or unnecessarily overblown and even highfalutin. Coming from the Italian word grandioso (meaning "grand" or "noble"), the adjective grandiose is kind of like Italian hand gestures: big, exaggerated, and over the top. And it's that excessiveness that pushes something grand (large, with an air of distinction) into grandiose (large, but trying too hard) territory.
