see through something or someone

Meaning: To not be fooled by a false front or disguise that someone presents in order to mislead; to understand the true nature of someone or something.

Example: “The children saw through their father's fake surprise immediately.”

Origin: The figurative sense of "seeing through" someone or something — perceiving the real truth hidden beneath a deceptive surface — is documented from the 1500s, building on a much older, universal metaphor equating clear understanding with clear vision. The image works exactly the way looking through a pane of transparent glass does: an untrained or credulous eye stops at the surface, taking an appearance or a lie at face value, while a sharper, more skeptical one looks past that surface entirely to whatever real intention or fact lies behind it.
