‘审定’ is a formal verb meaning ‘to approve after careful review’ or ‘to finalize (a document, standard, textbook, etc.)’. It combines 审 (shěn), meaning ‘to examine, inspect, or scrutinize’, and 定 (dìng), meaning ‘to decide, determine, or fix’. Together, they convey the idea of reaching an official, authoritative conclusion after thorough evaluation. This word emphasizes both the rigorous review process and the resulting binding decision.

It is commonly used in official, academic, or technical contexts — for example, when government bodies approve national standards, publishers finalize textbooks, or research institutions ratify guidelines. It implies authority and finality: once something is 审定, it becomes officially sanctioned and ready for implementation or publication. It is rarely used in casual speech and almost never with people as objects — you don’t ‘审定 a person’, only documents, plans, versions, or standards.
