审定
shěn dìng · HSK 7
to examine and approve
🔍✅ 审 (examine) + 定 (settle/fix) = examine and then finalize
审 carries the sense of reviewing or scrutinizing; 定 means to settle, fix, or decide. Together they describe checking something over and then locking it in as approved or final.
定 — roof 宀 + 正 (correct/upright, phonetic)
Originally written with 宀 (roof) over 正 (upright/correct), suggesting a household settled and orderly under its roof. Over time 正 simplified to 㐬-like form at the bottom, and the meaning shifted from 'settled home' to the broader senses of 'fix, stable, decide.'
