The phrasal verb "pass off" is more commonly used in informal contexts than in formal speech, although it can appear in formal writing when casual metaphors or idiomatic expressions are appropriate. It generally means to present something falsely, often in a deceptive manner, such as when someone "passes off" imitation goods as genuine, or when misinformation is "passed off" as the truth. The verb can also describe events that transpire smoothly or without incident, as in "the event passed off without a hitch." Usage patterns show "pass off" frequently appearing in narratives, both written and spoken, where deception, transition, or smooth occurrence are thematically important. Moreover, the phrasal verb may also appear reflexively ("pass oneself off") when someone tries to assume a false identity or status. This versatility allows it to fit naturally into various contexts, particularly where nuance or subtlety is required.
