Interpolate comes from Latin interpolare, a verb with various meanings, among them "to refurbish," "to alter," and "to falsify." Interpolate entered English in the 17th century and was applied early on to the alteration (and in many cases corruption) of texts by insertion of additional material. Modern use of interpolate still sometimes suggests the insertion of something extraneous or spurious, as in "she interpolated her own comments into the report."
