Morphology

capacitor = capacity (semi-transparent) = capacit + or

The word is built on the idea of electrical capacity plus the agentive/instrumental suffix -or, but the technical sense is specialized and not fully predictable for an average learner.

Etymology

Capacitor comes from the Latin root capacit-, which means 'ability to hold' and is the same root in familiar words like capacity and capable. So a capacitor is like a small 'container' for electric charge, storing energy and giving it back when a circuit needs it.
