Chinese character 訚

It describes respectful, principled disagreement.

The word names a way of speaking: a person makes a serious point while keeping the exchange harmonious. The Shuowen Jiezi, an early Chinese character dictionary, defines the traditional form 誾 along these lines. In the Analects, a collection of teachings and conversations associated with Confucius, the doubled form 誾誾 describes speech addressed to senior officials. A recognizable form of 誾 is recorded on a bronze inscription from the late Western Zhou.

Is 訚 the simplified form of 誾?

Yes. 誾 is the traditional-script counterpart of 訚.

The two forms represent the same Chinese word, and dictionaries list 訚 as the simplified counterpart of 誾. Classical set phrases also build on the doubled form, as in 訚訚侃侃, which describes courteous, sincere, unhurried speech.
