Morphology

arrestor = arrest (transparent) = arrest + or

The suffix '-or' is transparently used to indicate an agent or device that performs the action of the verb 'arrest'.

Etymology

Arrestor: The word arrestor comes from the verb arrest, which means 'to stop' and is the same word used when police stop someone. The ending -or means 'something that does', so an arrestor is a device that 'stops' movement for safety.
