Morphology

oscillation = oscillate (transparent) = oscillate + ion

A regular noun formed from the verb 'oscillate' using the nominalizing suffix '-ion'; the meaning directly relates to 'oscillate'.

Etymology

The word oscillation comes from the Latin verb oscillare, which means 'to swing'. So, when something moves regularly between two states, like optimism and pessimism, that back-and-forth is an oscillation.
