Morphology
modulate = modul + ate
The verb is formed from the combining form 'modul-' plus '-ate'; the technical sense (varying wave characteristics) follows the general meaning 'adjust or change' but the morphemic parts are not everyday words for B1 learners, so inference is only partially reliable.
Etymology
The word modulate comes from the Latin root modus, meaning 'measure', and is related to mode and moderate. In signals and radio this idea becomes 'change the measure' of a wave so it can carry information, so to modulate is to vary a signal to send data.
