IPA: /ˈkɑːr.pɔːrt/
KK: /ˈkɑrˌpɔrt/
A structure with a roof that provides shelter for a car, typically open on the sides and attached to a building.
We parked the car under the carport to protect it from the rain.
Carport is formed from "car" (from Latin *carrus*, meaning a wheeled vehicle) and "port" (from Latin *portare*, meaning to carry). The word describes a structure that carries or shelters a car.
Think of a structure that 'carries' ('port') your 'car' — that's what a carport is for.
