Morphology

waveform = wave + form (transparent) = wave + form

The compound combines 'wave' (a signal oscillation) and 'form' (shape), so the meaning 'shape of a wave' is directly inferable by learners.

Etymology

The word waveform joins wave, a moving swell of water or sound, and form, meaning 'shape', so it literally names the 'shape of a wave' you see on a graph.
