Surface Forms

arrestor singular

Morphology

arrestor = arrest (transparent) = arrest + or

Formed by the verb 'arrest' plus the agent/device-forming suffix '-or'; the lightning-specialized sense is a predictable extension of 'to arrest' (to stop/divert surges).

Etymology

Arrestor: The word arrestor comes from arrest 'to stop' plus the ending -or 'something that does'. So an electrical arrestor 'stops' sudden extra electricity by sending it away to protect machines and wires.
