fake, counterfeit
偐 centers on deception through imitation: something fake or counterfeit that is made to look genuine.
偐 combines 亻 (person) with 彦, which likely contributes the sound. The exact historical development is uncertain, but the character is associated with the idea of a person who is not genuine.
A person 亻 beside 彦, which looks like a fancy or decorated figure. Imagine someone dressed up to look impressive but actually being a fake.
For ゲン, picture a counterfeit genie lamp: genie -> ゲン, and the fake lamp is held by the person 亻 on the left.
