确认 (què rèn) is a transitive verb meaning 'to confirm' or 'to verify' — to check and establish that something is true, accurate, or agreed upon. The first character 确 (què) means 'certain' or 'definite', while 认 (rèn) means 'to recognize' or 'to acknowledge'. Together, they express the act of making something certain through recognition or verification. It’s commonly used in formal, professional, and everyday contexts — such as confirming appointments, orders, identities, or facts.

This word often appears after subjects like 我们 (we), 他 (he/she), or system prompts (e.g., 请确认). It typically takes a direct object (e.g., 信息, 时间, 身份) or follows a clause introduced by whether/that (e.g., 是否…, …是否…). Unlike casual alternatives like 对一下 (duì yí xià), 确认 carries a tone of reliability and procedural care, making it frequent in digital interfaces, customer service, healthcare, and administrative communication.
