彰明较著 is a formal, literary adjective meaning 'strikingly obvious' or 'self-evident'. It emphasizes clarity so strong that no explanation is needed — the truth or fact stands out unmistakably. The four characters work together: 彰 (to make evident), 明 (clear, bright), 较 (to compare, here implying contrast that highlights difference), and 著 (conspicuous, prominent). Together, they reinforce the idea of something so clear it’s immediately apparent to all.

This phrase is commonly used in written Chinese — essays, news reports, legal documents, or formal speeches — to underscore undeniable evidence, outcomes, or consequences. It carries a tone of authority and objectivity, often describing facts, effects, or results that are beyond dispute. While grammatically an adjective, it typically modifies nouns like 'fact', 'evidence', 'result', or 'difference', and frequently appears after a subject or in predicate position with 是 or 为.
