KK: /ˈpærəˌpɛtɪd/
Describing something that has a low wall or barrier at the edge, often found on rooftops or along the sides of buildings.
The castle was protected by a parapeted wall that offered a great view of the surrounding landscape.
Parapeted is derived from "parapet" (from Old French *parapet*, meaning a low protective wall) and the suffix "-ed" (indicating a state or condition). The word "parapeted" means having a parapet or being equipped with a protective wall.
Think of a 'low protective wall' ('parapet') that provides safety, and the '-ed' shows that something is in that state.
