Morphology

extrapolate = extra + polate

The prefix 'extra-' ('beyond') is transparent and signals the general idea of 'beyond/outer', but the stem '-polate' is a learned combining form (not a standalone English verb), so learners cannot fully derive the precise verbal meaning from components alone.

Etymology

Extrapolate starts with extra-, which means 'outside' or 'beyond', and the ending -polate sounds like 'plot', so you can picture drawing a line and pushing it past the last known points. So, to extrapolate is to extend what you know 'outside' the data to make a careful guess about what comes next.
