What does interpolating mean?
Interpolating means inserting or blending material into an existing text, sequence, or medium. It can refer to literary or editorial work, as when new dialogue is woven into a recording, but it is also a technical term for estimating values that lie between known data points. In mathematics, statistics, graphics, and computer science, interpolating code calculates such intermediate values from surrounding observations. The word may carry a slight suggestion of smoothness or careful integration, although interpolation can also be used neutrally for any insertion into an existing structure. It should not be confused with extrapolation, which goes beyond the range of available data rather than filling gaps within it. Interpolating is therefore a useful word for describing both the creative blending of material and the technical reconstruction of missing or intermediate values.
Relating to the insertion or blending of material into an existing text, medium, or data series.

Where does interpolating come from?
The word comes from Latin interpolare, meaning “to alter by inserting” or “to furnish with insertions.” That form combines the prefix inter-, meaning “between” or “into,” with polire, “to polish,” reflecting the original idea of smoothing material into a text. English adopted the term in the early 19th century, and it later developed a specialized mathematical and computing sense involving the estimation of intermediate values.
