坚定
jiāndìng · HSK 5
steadfast
⚓ 坚 = solid/hard + 定 = settled/fixed → firmly fixed, steadfast
坚 carries the sense of hard or solid (think 坚固 sturdy), and 定 means settled or determined (as in 决定 decide). Together they describe a stance that is hard-set and unwavering — firm, resolute, steadfast.
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.'
