Surface Forms

reactor singular

Morphology

reactor = react (transparent) = react + or

Formed regularly from the verb 'react' with the agent/instrument suffix '-or', denoting a device where reactions occur.

Etymology

Reactor comes from the verb react ('to respond' or 'act back') and the ending -or that means 'something that does'. So a reactor is something that makes or controls a reaction, which is why a nuclear reactor keeps a controlled reaction to produce energy.
