Chinese character 鈋

It describes rounding a square by removing its corners.

The Chinese gloss 去角 means “remove corners.” The earliest surviving dictionary entry is in 說文解字, an Eastern Han Chinese dictionary. Later Chinese dictionaries, including 玉篇, 廣韻, and 字彙, preserve definitions for cutting away corners or rounding a square.

What does 鈋 mean when someone sends it?

A lone 鈋 does not reveal which historical sense the sender intends.

In the Northern Qi period, the scholar Yan Zhitui used 鈋鈍 in 顏氏家訓, a book of family advice, to describe speech as heavy, rough, and old-fashioned. The phrase carries an edge’s bluntness into a sharp judgment on someone’s way of speaking.

If someone sends only 鈋, ask what passage or idea they have in mind; the character alone cannot settle which historical sense they mean.
