the.com/doorman

means Someone employed to greet, assist, and screen people entering a building, usually holding the door open as part of the job.

from A plain compound of 'door' plus 'man,' the job-noun suffix English uses constantly (postman, milkman, fireman) — naming the role by naming what it stands beside. It likely entered common use alongside the rise of grand apartment buildings and hotels, where having staff posted at the entrance became a mark of status. No hidden story here — the word is exactly as literal as it looks, which is part of its charm.
