Morphology

interpolate = inter + polate + ate

The idea of placing or estimating something 'between' is suggested by 'inter-', but because 'polate' is not a familiar standalone English root, the derivation to a numerical estimation is only partially transparent to learners.

Etymology

Interpolate comes from Latin parts inter- 'between' and polire 'to polish', which gives the picture of putting something between two things. So in maths or data work, to interpolate is to 'insert' an estimated value between two known values.
