Han character 叛

叛 centers on a breach of loyalty. It frames an act against a person, group, or authority as disloyalty, not just disagreement.

Its small-seal form appears in Shuowen Jiezi, an early Chinese dictionary. Small seal was an old standardized style of Chinese writing. The dictionary analyzes 叛 as a sound-and-meaning character: 反 contributes the meaning association, and 半 points to the sound.

Is 叛 rude?

Yes, if you mean to accuse someone of disloyalty or rebellion. It is a serious charge, not a light expression.

Sent alone, it leaves the target unclear. Check the language and surrounding words before deciding who or what is being accused.

Japanese references list 反 as a replacement form for 叛. In Korean Hanja usage, 叛 is read 반 and can carry the sense of plotting or rebellion. The shared character has different readings and familiar word forms across languages.

Use 叛 for a broken allegiance

Compounds specify the charge: 叛徒 names a traitor, 叛国 means betrayal of a state, and 叛逆 means rebellion or a rebel.

This wording takes a side: it casts one party as loyal and the other as having broken faith. Use it for that accusation, not for every protest or disagreement.

The drawn strokes can vary across Chinese, Japanese, and Korean fonts. A regional font shape can look different while representing the same Han character.
