What adjective describes someone or something that is pompous or pretentious?

The term "highfalutin" effectively captures the essence of being pompous or pretentious. This adjective typically describes language, behavior, or attitudes that are overly extravagant, lofty, or assertive, often intended to impress others but may come off as insincere or unnecessary.

In contexts where individuals or ideas are seen as trying to appear more important or sophisticated than they actually are, "highfalutin" aptly conveys this sense of inflated self-importance. It is often used to critique or point out when someone tries too hard to sound refined or educated, which can be perceived as lacking authenticity.

In contrast, the other options present different concepts that do not align with the idea of being pompous or pretentious. For instance, "humdrum" suggests something monotonous or unexciting, while "humble" denotes a lack of arrogance and is characterized by modesty. Similarly, "honest" conveys truthfulness and integrity, which is an entirely different quality. Thus, "highfalutin" stands out as the appropriate choice for describing a pompous or pretentious demeanor.
