interpolate

Fill in gaps

Interpolate means to insert something between existing elements.

In mathematics, to interpolate is to estimate unknown values between known data points: We interpolated the missing temperature readings from the surrounding measurements.

In textual scholarship, interpolation refers to later additions inserted into original documents—often with connotations of corruption or forgery.

More generally, to interpolate is to interject remarks into a conversation or narrative: She interpolated a question before he could finish.
