INTER(between) + POLATE(like plate) = INSERT the plate BETWEEN two other plates.
imagine an angry POLE dancer saying to one of his customers.."if you flirt with me physically,i shall INTERPOLATE this POLE b/w your two legs....!!!".....:)
EXTRAPOLATE means to draw out. INTERPOLATE means to insert in.
inter(between) + (poles of a horseshoe magnet) + ate -> to insert between to poles...
