Did You Know?
"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."
