Word Origin & History

1612 (implied in interpolation) "to alter or enlarge (a writing) by inserting new material," from L. interpolatus, pp. of interpolare "alter, freshen up, falsify," from inter- "up" + polare, related to polire "to smoothe, polish." Sense evolved in L. from "refurbish," to "alter appearance of," to "falsify
(especially by adding new material)."
