‘践诺’ is a formal, literary verb meaning 'to fulfill a pledge' or 'to keep a promise.' It combines two characters: 践 (jiàn), which literally means 'to tread on' or 'to carry out,' and 诺 (nuò), meaning 'a promise' or 'a vow.' Together, they evoke the image of stepping forward to honor one’s word—emphasizing action, integrity, and moral responsibility. The term carries strong connotations of trustworthiness and accountability.

This word is commonly used in written Chinese—such as news reports, official statements, speeches, or essays—and appears less frequently in casual spoken conversation. It often describes commitments made by individuals, organizations, or governments, especially when those promises involve public interest, contracts, or ethical obligations. While similar in meaning to everyday terms like '守信' (to keep one’s word), '践诺' has a more solemn, weighty tone and implies deliberate, concrete follow-through.
