‘大彰’ is a literary, formal verb meaning 'to greatly reveal,' 'to prominently display,' or 'to widely promote.' It combines 大 (dà), meaning 'great' or 'greatly,' and 彰 (zhāng), meaning 'to make evident,' 'to highlight,' or 'to glorify.' Together, they intensify the idea of making something unmistakably visible, celebrated, or known—often with positive moral, cultural, or virtuous connotations. The word carries classical resonance and appears frequently in historical texts, official proclamations, and formal writing.

It is rarely used in spoken Mandarin or casual contexts. Instead, it’s found in set phrases like 大彰正义 (dà zhāng zhèngyì, 'to powerfully uphold justice') or 大彰孝道 (dà zhāng xiàodào, 'to highly extol filial piety'). Because of its elevated register, learners should avoid using it in everyday conversation or informal emails; it belongs in speeches, editorials, or ceremonial language where rhetorical weight and traditional values are emphasized.
