Morphology

subharmonic = harmonic (semi-transparent) = sub + harmonic

The word is transparently formed from 'sub-' and 'harmonic' but denotes a technical fractional relation that requires domain knowledge.

Etymology

A subharmonic is a lower frequency: sub- means 'below' and harmonic comes from harmony meaning 'fitting together'. So a subharmonic is a tone like one-half or one-third of the main frequency that still 'fits' the original sound.
