威望 (wēi wàng) refers to prestige and authority earned through one's accomplishments, character, or position — it implies respect and influence others willingly give. It is similar to 威信 (wēi xìn, moral authority) but focuses more on the prestige itself than on the trust component; 声望 (shēng wàng) is a broader term for general reputation and renown. 威望 is typically used for respected figures like scholars, generals, or leaders.
