false charge, hatred
冤 centers on being wrongfully accused or blamed, leading to a sense of injustice and resentment. The hatred meaning is a natural emotional response to such false charges.
冤 combines 冖 (cover) and 兔 (rabbit), suggesting a rabbit trapped under a cover, symbolizing being wrongfully confined or accused. The exact historical development is uncertain, but the component combination is widely accepted.
A rabbit 兔 is trapped under a cover 冖, unable to escape a false accusation. The rabbit's frustration turns to hatred.
For エン, imagine the rabbit shouting 'Innocent!' but it comes out as 'En!' because of the cover: En -> エン, and the rabbit is falsely charged.
