The word 即便 is formed through the combination of two synonymous and reinforcing characters, 即 and 便, which both historically carry core meanings related to "immediacy", "then", or "in that case". By joining them, the compound intensifies the sense of introducing a hypothetical or contingent circumstance, essentially meaning "precisely even if" or "right in that event", which solidifies into its modern function of introducing a concessive condition, meaning "even if".
