Describing a structure that has features like a castle, such as towers and battlements.
The old mansion was castellated, giving it a fairy-tale appearance.
Castellated is formed from "castellum" (meaning a small castle or fortified place) and the suffix "-ated" (indicating a state or condition). The word describes something that is in the state of being like a castle, often referring to buildings with battlements or castle-like features.
Imagine a building that is in the 'state' ('-ated') of being like a 'small castle' ('castellum') — that's what castellated means.
