The compound word "逼真" is formed through a figurative combination of its two constituent characters: "逼" (bī), which means "to approach" or "to press close," and "真" (zhēn), which means "real" or "true." Together, they create a meaning that is greater than the sum of its parts, conveying the idea of something being "so close to reality that it seems real." The word thus describes an image, imitation, or representation that is exceptionally lifelike, vivid, and convincing, as if it is pressing up against the boundary of truth itself.
