armor

This word carries a heavy association with medieval warfare and steel, evoking images of rigidity, weight, and total enclosure. It suggests a barrier that is physically impenetrable, creating a sense of isolation between the wearer and the external threat.

In modern psychological contexts, the term describes emotional defenses. When someone puts up armor, they are not just protecting themselves, but are intentionally blocking intimacy or vulnerability to avoid being hurt, often resulting in a cold or distant demeanor.
