Surface Forms

breaker singular
breakers plural

Morphology

breaker = break (semi-transparent) = break + er

Formed from 'break' + '-er' but the specialised technical sense ('circuit breaker') denotes a specific safety device and may not be fully inferable by lower-level learners from the verb alone.

Etymology

Breaker comes from the verb break ('to stop or open') plus -er, so it means 'something that breaks'. That is why a circuit breaker is a device that 'breaks' the flow of electricity to protect the system.
