inter- (between) + the polīre/interpolāre stem ('refurbish, touch up') + -ate. Latin interpolāre meant to patch new material into an old text. The math sense narrowed it: to interpolate is to fill in a value that sits between two known data points. Its mirror, extrapolate, reaches beyond the known range.
