Morphology
spectrogram = spectrum (semi-transparent) = spectro + gram
The relation 'spectrum' + '-gram' ('a recording of a spectrum') is derivable but uses technical combining forms that may be unfamiliar to general learners.
Etymology
Spectrogram breaks into spectro- meaning 'look' or 'image' (as in spectrum and spectacle) and -gram meaning 'something written' (as in telegram). So a spectrogram is like a 'written picture' of a spectrum that shows different frequencies and how strong they are, which is why we use it to view sound or light patterns.
