IPA: /ˈruːfləs/
KK: /ˈrufləs/
Describing a place or situation that does not have a roof, or referring to someone who is without a home or shelter.
The roofless building stood abandoned in the middle of the city.
Roofless → It is formed from "roof" (from Old English "hrof", meaning the top covering of a building) and "-less" (meaning without). The word "roofless" means without a roof or lacking a top covering.
Think of a building that is missing its 'roof' — the '-less' part indicates it is without something. This helps you remember that 'roofless' means lacking a roof.
