Origin

This character combines a roof or shelter shape with a cross and an eye to depict a shield. The roof-like top component suggests a protective covering, while the cross and eye below represent the face or front of the shield where a warrior would look out or aim. Together, these parts visually suggest an object designed to protect and defend. Over time, the character came to mean shield in general, and then extended to mean a pretext or excuse—something used to defend oneself figuratively, just as a physical shield defends in battle.
