impostor: [16] An impostor is etymologically someone who ‘imposes’ on others. The word comes via French imposteur from late Latin impostor, a contraction of classical Latin impositor. This was a derivative of imponere ‘put on’, hence ‘inflict, deceive’ (a compound verb based on ponere ‘put, place’), which also gave English impose [15], impost ‘tax’ [16], and imposture [16]. It is the ‘deceive’ sense of imponere, of course, that has come through into impostor.
