Chinese character for a slender waist

嫢 is a rare literary word for a slender or graceful feminine form.

A commentary links 嫢 to the Western Han Fangyan, a collection of regional words; the Eastern Han Shuowen Jiezi, an early Chinese character dictionary, explains it through 媞 and records a Qin–Jin period Chinese sense of something fine or slender.

The character combines 女, a woman-related component that points toward meaning, with 規, which points toward sound. Later dictionary entries extend the glosses to a slender waist, something small or fine, and a woman’s attentive or refined appearance; under another sense, it describes an ample bearing.

What does 嫢 mean in a message?

Treat it as a rare dictionary word; the sentence decides which sense fits.

Alone, it can be hard to read as an ordinary compliment: it may be a quotation from an old text or a deliberately literary word. Ask for the sentence around it; if the sender simply means “beautiful,” a common word is clearer.

The relevant language matters: Mandarin and Cantonese dictionaries, and Japanese and Korean references, list different readings. No single reading covers all four traditions.
