Thesaurus Entry
Cultural Origin & Etymology

Coined in the mid-19th century as a back-formation from 'extrapolation', modeled on 'interpolate'. It combines the Latin 'extra' (outside, beyond) with 'polare' (to polish, alter, or work, from 'polire'), influenced by mathematics to mean extending a curve or method beyond known data points.

Memory Aid & Mnemonic

Think of 'extra' (beyond) plus 'polate' (related to points); you are taking data *extra* (outside) the known points.
