beautiful, fair, handsome
妤 centers on physical attractiveness, describing someone who is beautiful, fair, or handsome.
妤 combines 女 (woman) with 予, which likely contributes the sound. The character is used to express feminine beauty.
A woman 女 beside 予: imagine a woman whose appearance is so striking that it is given 予 (beforehand) attention—she is beautiful.
For ヨ, picture a beautiful woman saying 'yo!' as a greeting: yo -> ヨ, and her beauty makes the greeting memorable.
