intelligence, imperial
叡 centers on deep, penetrating insight, especially the kind associated with wise or imperial judgment. The 'imperial' sense is a specific application of that profound intelligence.
叡 combines 睿 (deep understanding, wise) with 又 (hand), possibly reinforcing the idea of active, discerning intelligence. The exact historical development is uncertain, but the components consistently point to profound insight.
The left side 睿 suggests a penetrating eye (目) under a cover (冖) with marks of discernment above, while the right side 又 is a hand. Together, they picture a hand lifting the cover to reveal deep, imperial-level intelligence.
For エイ, imagine an emperor named 'A' (エイ) who possesses supreme intelligence, using his hand (又) to uncover hidden truths.
