grievance, injustice, wrong
寃 centers on a sense of being wronged: a grievance, an injustice, or something that is not right.
寃 is a variant form of 冤. It combines 宀 (roof) with 兔 (rabbit), suggesting a rabbit trapped under a roof, symbolizing being wrongfully confined or oppressed. The exact historical development is uncertain, but the component combination is consistent with the meaning of grievance.
A rabbit 兔 is stuck under a roof 宀, unable to escape. This trapped feeling represents a grievance or injustice—being wronged with no way out.
For エン, imagine the rabbit crying out 'Enough!' (エン) because of the injustice of being trapped under the roof. The sound 'en' echoes its grievance.
