Morphology

spectrography = spectrograph (semi-transparent) = spectro + graph + y

The immediate base 'spectrograph' is technical, so the suffixal formation is regular but the specialized meaning is only partly predictable for an average learner.

Etymology

Spectrography combines spectro- (seen in spectrum, meaning 'range') and -graphy (seen in photography, meaning 'writing' or 'recording'). So spectrography is like 'writing the range' of sound as a picture, which is why researchers use it to show and study different sound frequencies in speech and animal calls.
