IPA: //ˈbreɪk.mən//
KK: /ˈbreɪkˌmæn/
A person who is part of a train crew and is responsible for inspecting the train and helping the conductor, or a member of a bobsled team who operates the brakes.
The brakeman checked the train's safety equipment before departure.
Brakeman → The word is formed from "brake" (from Old English *bracan*, meaning to break) and "man" (meaning a person). A brakeman is a person responsible for operating the brake on a train or vehicle, thus relating to the action of breaking or stopping.
Think of a 'brake' as something that 'breaks' the movement, and a 'man' is the person who operates it. This helps you remember that a brakeman is the person who stops or controls the train.
