The word "interpolate" originates from Latin interpolare, meaning "to refurbish or alter." It combines inter- (between) and polire (to polish or refine). Historically, it referred to altering texts by inserting new material, later expanding to mathematical contexts (estimating intermediate values). The morpheme pol reflects the idea of refining or smoothing data or text.
