heterodyne positive

Morphology

heterodyne = dyne (opaque) = hetero + dyne

Although 'hetero-' (different) is visible, the element '-dyne' is a technical combining form (or a unit name) that does not mean 'frequency', so the specific sense 'mixing frequencies' is not predictable to an average learner.

Etymology

Heterodyne comes from the parts hetero- meaning 'different' and dyne meaning 'force', the same root you see in dynamic. It gives the image of different waves or forces mixing to make new 'beat' frequencies, which is why a heterodyne system produces sum and difference frequencies.
