道歉 means 'to apologize' — a formal, respectful verb used when acknowledging fault or expressing regret for a mistake, offense, or inconvenience caused to others. The character 道 (dào) literally means 'to speak' or 'to express', while 歉 (qiàn) means 'regret' or 'apology'. Together, they form a compound verb emphasizing the intentional act of voicing remorse. It’s commonly used in face-to-face conversations, written messages, and public statements.

This word carries a tone of sincerity and responsibility. Unlike casual expressions like 对不起 (duì bu qǐ), 道歉 is more deliberate and often implies accountability — it’s frequently used in contexts requiring maturity and social awareness, such as workplace errors, family misunderstandings, or official communications. It can appear as a standalone verb ('我向你道歉') or in noun form ('真诚的道歉'), but note that as a verb, it typically requires an object or direction (e.g., 向…道歉 or 为…道歉).
