腷

It marks held-in feeling or imitates a sound in Chinese compounds.

In 腷臆, it describes anger or grief that stays bottled up. In 腷腷膊膊, repetition imitates wingbeats or cracking ice; the surrounding scene tells you which sound is meant.

The character appears in Han fu, a classical Chinese prose-poetry form. During the Three Kingdoms period, the writer Cao Pi used 腷臆 in 武帝哀策文, a funeral text for his father, to describe grief held in. By the Song dynasty, 腷膊 appeared in poetry for clattering or flapping sounds, including scenes involving hens, birds, and a game.

What does 腷 mean when someone sends it alone?

Ask which compound or language they mean.

Used chiefly inside compounds, 腷 alone cannot tell you whether the sender means restrained emotion, a sound, or a regional reading. Ask for the word or language instead of assigning it one chat meaning.

A Chinese, Japanese, or Korean font supplies 腷's visible strokes. Fonts can draw it differently or lack a usable glyph; that changes the display, not the encoded character.
