IPA: /ˈmeɪnˌmæst/
KK: /meɪnˌmæst/
The main vertical pole on a sailing ship that supports the sails and rigging.
The crew worked hard to raise the mainmast of the ship before setting sail.
**Mainmast** → The word is formed from "main" (from Old French *main*, meaning principal or chief) and "mast" (from Old English *masta*, meaning a tall vertical structure on a ship). The term "mainmast" refers to the principal mast of a sailing vessel, which is the tallest and most important mast.
Think of the word 'main' meaning principal or chief, and 'mast' as the tall structure on a ship. This helps you remember that the mainmast is the chief mast on a sailing vessel.
