beautiful girl
嫮 centers on feminine beauty, specifically a beautiful girl or woman. The meaning is narrow and concrete, without strong abstract extensions.
嫮 combines 女 (woman) with 雩, which likely contributes a phonetic element. The exact historical development of 雩 in this character is uncertain, but the structure suggests a phono-semantic compound related to feminine beauty.
A woman 女 beside a decorative, rain-like shape 雩: imagine a beautiful girl adorned with delicate rain droplets, enhancing her beauty.
For コ, picture a beautiful girl named ココ (Coco) standing in the rain: Coco -> コ, and her beauty shines even in the rain.
