People or devices that share information, ideas, or messages with others.
From Latin 'communicare' (to share/make common), derived from 'communis' (common). The '-or' or '-er' suffix creates a noun meaning 'one who does the action.'
Good communicators are rarer than you'd think—studies show most miscommunication happens not because people don't talk, but because they assume understanding without actually verifying it happened!
