bride, marriage
嬪 centers on a woman entering a formal union: a bride or marriage. The idea is specifically about the woman's role in the marital relationship.
嬪 combines 女 (woman) with 賓, which likely contributes the sound and may relate to the idea of a guest or formal ceremony, suggesting a woman entering a new household through marriage.
A woman 女 beside 賓, which looks like a formal guest under a roof. Picture a bride being welcomed as an honored guest into her new family.
For ヒン, imagine the bride giving a little hint about the wedding plans: hint -> ヒン, and the woman 女 is the bride.
