Aft

Aft, in naval terminology, is an adjective or adverb meaning, towards the stern (rear) of the ship, when the frame of reference is within the ship. Example: "Able Seaman Smith; lay aft!". Or; "What's happening aft?"

Aft also describes the direction of movement within an aircraft; that is, towards the tail. Example: "Let's go aft." Meaning to pull back on the yoke. It may also describe the back/tail location or region within an aircraft cabin. Example: "Aft lavatory."

The difference between aft and stern is that aft is the inside (onboard) rearmost part of the vessel, while stern refers to the outside (offboard) rearmost part of the vessel.
