Hochstapler (m)
ˈhoːxˌʃtaːplɐ
A Hochstapler deliberately assumes a false identity or claims credentials they have never earned, often sustaining the deception for years with considerable skill. The best English equivalent depends on whether the focus is on the false persona, the fraudulent gain, or the pretense of expertise.
1. impostor
Best when the deception centers on a fabricated identity or credentials, e.g., a fake doctor, officer, or nobleman.
2. con artist [informal]
Emphasizes the scheming and manipulation for personal gain, the right choice when the deception is primarily about money or material profit.
3. charlatan · figurative
Fits when someone pretends to possess professional expertise they lack, especially in medicine, science, or advisory roles.
Notes
The word literally evokes 'stacking high', piling up lies, bogus titles, or fabricated status. English has no single word that captures this image: 'impostor' stresses the false identity, 'con artist' the deceptive scheme, and 'charlatan' the pretense of expertise. All three are genuine translation options; context determines which fits best.
