Morphology

electroretinogram = retinogram (semi-transparent) = electro + retina + gram

The term is structurally compositional as an electrical version of a retinogram, but the medical specialization makes it less immediately guessable for an average learner.

Etymology

The word electroretinogram comes from three parts: electro- 'electricity', retina 'the back of the eye that senses light', and -gram 'a record', as in the familiar word telegram. So an electroretinogram is a 'record' of the eye's electrical signals, which is why the test measures how the retina responds to light.
