Why this word
An impostor is someone who falsely claims to be another person or to have qualifications they do not possess. The term covers many situations: someone stealing a real person's identity, a person falsely claiming to be a doctor or lawyer, or even someone just pretending to belong in a social group. "Impostor syndrome," a widely known psychological term, describes the feeling of being fraudulent despite actual success. The key difference from "poseur" is that an impostor's deception is typically more serious and intentional, while a poseur often adopts a false image for style or effect. "Charlatan" is more specific—it refers to someone making false claims about expertise or special powers, often to swindle others. All three imply some form of pretense, but impostor is the most general and commonly used word for this concept.
