Which word describes something ostentatiously lofty in style?

The word "bombastic" is used to describe language or style that is pompous or overly inflated, often characterized by grandiose exaggerations and an ostentatious display that may lack substance. When something is described as "ostentatiously lofty in style," it implies that the manner of expression is meant to impress others, often at the expense of clarity or sincerity. The term captures the essence of a showy or theatrical approach, which aligns perfectly with the idea of being lofty in a way that tries to be impressive.

For additional context, "immaculate" refers to something that is flawless or perfectly clean, lacking the ostentatious qualities associated with bombast. "Glacial" describes something that is cold or slow-moving, often relating to ice, and does not convey any sense of elevated or lofty style. "Unsightly" refers to something that is not pleasant to look at, which is the opposite of being lofty or impressive in any context. Therefore, "bombastic" stands out as the correct choice due to its specific connotation of ostentatiousness and lofty style.
