Morphology

oscillogram = oscillation (transparent) = oscill + gram

The word is a regular combination of the stem meaning 'oscillation' and the productive suffix '-gram' meaning 'a record or writing', so the meaning 'record of oscillations' is directly derivable.

Etymology

Oscillogram comes from the Latin oscillare, which means 'to swing', and the ending -gram, which means 'a thing written', like in telegram. So an oscillogram is a 'written' picture of a signal's swings or waves, which is why it shows how an electrical signal changes over time.
