Etymology
the word 'impostor' entered english in the 16th century from french 'imposteur', which itself derived from late latin 'impostor', meaning 'one who imposes upon or deceives'. this latin noun is an agent form of the verb 'imponere', composed of 'in-' (in, upon) and 'ponere' (to place). the literal sense is 'one who places upon', which evolved to mean 'one who imposes a false identity or a deception upon others'. the semantic journey is from the concrete act of placing something onto a person, to the abstract act of imposing a false character or claim, perfectly capturing the essence of a deceiver.

post: latin origin, from the verb 'ponere' meaning 'to place, to put'. the spelling 'post' reflects a past participle form.
or: latin origin, an agent noun suffix indicating 'a person or thing that does something'.
