披露 (pī lù) is a formal verb meaning 'to disclose' or 'to reveal' information that was previously hidden, confidential, or unknown. The character 披 (pī) originally means 'to spread open' or 'to drape', suggesting the act of uncovering or laying something bare; 露 (lù) means 'to show' or 'to become visible', reinforcing the idea of making something apparent. Together, they form a compound emphasizing intentional, often official or public, revelation—common in journalism, law, medicine, and corporate communications.

This word carries a neutral-to-serious tone and is rarely used in casual speech. It typically appears with abstract nouns as objects (e.g., 信息, 秘密, 真相, 数据), and frequently follows subjects like 政府, 医院, 公司, or 记者. Unlike colloquial alternatives like 说 or 告诉, 披露 implies authority, responsibility, or consequence behind the revelation—often tied to transparency, accountability, or regulatory compliance.
