'核实' (hé shí) is a transitive verb meaning 'to verify' or 'to check (the accuracy or truth of something).' It combines the characters 核 (hé), which means 'core,' 'nucleus,' or 'to examine closely,' and 实 (shí), meaning 'real,' 'true,' or 'substance.' Together, they convey the idea of examining something down to its core to confirm its reality or correctness. This word emphasizes careful, often official or procedural, confirmation—common in administrative, journalistic, medical, or legal contexts where factual accuracy is critical.

The verb typically takes a direct object (e.g., information, facts, data, documents, or reports) and is often used in formal or professional settings. It implies a methodical process—not just a casual glance, but a deliberate effort to ensure reliability. You’ll frequently encounter it in phrases like '核实信息' (verify information), '核实身份' (verify identity), or '核实情况' (verify the situation). While similar to '检查' (jiǎnchá, 'to inspect'), '核实' specifically stresses confirming truthfulness, not merely physical examination.
