Chinese character 歉

It signals regret, shortage, or a poor harvest.

An early written example appears on a bronze measuring vessel bearing a Qin edict from the Warring States period. The edict addresses unclear measurement standards; the Shuowen Jiezi, an early Chinese dictionary, glosses 歉 as food not being plentiful.

The food-shortage sense widened to general lack and later to personal regret. That history is why shortage and apology meanings coexist.

Should I send 歉 by itself?

Usually no; use the complete apology word.

抱歉 expresses regret; 道歉 names the act of apologizing. A bare 歉 is clipped and context-poor in modern Mandarin, so use the full word unless you are discussing the character itself.

Why does 歉 differ across languages?

Japanese keeps the shortage sense, not Mandarin’s everyday apology use.

Japanese usage includes meanings such as insufficiency and poor harvest; 歉 is not an everyday Japanese apology character. The Mandarin apology sense does not transfer automatically.
