Morphology

extrapolation = extrapolate (transparent) = extra + polate + ion

The noun is a regular nominalization of the verb 'extrapolate' and directly denotes the process named by the verb.

Etymology

The word extrapolation starts with extra-, meaning 'outside', and the rest comes from a part that means 'to place' or 'make', so it literally means 'estimating outside' the known data. That's why extrapolation is used to predict values beyond the information you already have.
