What does imposter mean?
An imposter is someone who pretends to be another person or claims qualifications, authority, or identity that they do not actually possess. The word commonly describes situations involving deception for personal benefit, such as impersonating a professional, posing as a company representative, or fraudulently obtaining money. It is especially frequent in reports about online fraud, in which criminals impersonate banks, government officials, or trusted acquaintances. “Imposter” is widely used in American English, while the closely related spelling “impostor” is standard in British English and many other varieties. Because the word carries a strong suggestion of deliberate misrepresentation, it is more accusatory and specific than the general word “pretender.” The related term “imposture” names the deception or fraudulent practice itself rather than the person responsible for it.

Where does imposter come from?
“Imposter” comes through French from the Latin impostor, a noun derived from imponere, meaning “to place upon” or “impose.” The word originally referred to a person who imposed a false claim or obligation on others. Its modern sense of someone falsely claiming another identity developed from that older meaning of imposing a deceptive claim. The related English words “impose,” “impost,” and “imposture” preserve the same Latin root.
How imposter is actually used
