good looking
娧 centers on being visually pleasing or attractive, specifically applied to a person's appearance. The single given meaning 'good looking' captures this straightforward idea.
娧 combines 女 (woman) with 兑, which likely contributes the sound. The exact historical development is uncertain, but the structure suggests a phono-semantic compound where 女 indicates the meaning relates to a person's appearance.
A woman (女) beside the component 兑, which resembles a person with an open mouth and legs, can be imagined as a woman striking a confident, attractive pose. 娧 means good looking.
For タイ, picture a good-looking model tying her hair back: tie -> タイ, and her appearance is 娧.
