An opening in the side of a ship that allows a cannon to be fired.
The sailors prepared the cannon at the gunport for the upcoming battle.
Gunport → The word is formed from "gun" (from Middle English *gunne*, meaning a type of firearm) and "port" (from Old French *porte*, meaning a door or opening). A gunport refers to an opening or door designed for the placement or use of a gun.
Think of a 'door' ('port') specifically made for a 'gun' — that's what a gunport is, an opening for a firearm.
