A person who operates or helps to operate a ship at sea.
The mariner skillfully guided the vessel through the stormy waters.
**Mariner** → It is formed from "mar" (from Latin *mare*, meaning sea) and "-iner" (a suffix indicating a person associated with a particular activity). A mariner is a person who works on or is associated with the sea.
Think of someone who is connected to the 'sea' ('mar') — that's why a mariner is a person who works on the sea.
