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 comes from the parts spectro- (the same root as spectator and spectacle, meaning 'to look' or a 'range') and -graphy (like photography, meaning 'writing' or 'recording'). So spectrography is like 'recording the picture of light', which is why scientists use it to read light patterns and find what materials are made of.
