‘恒心’ literally means ‘constant heart’ — combining 恒 (hénɡ), meaning ‘permanent,’ ‘enduring,’ or ‘unwavering,’ and 心 (xīn), meaning ‘heart’ or ‘mind.’ Together, they form a noun expressing steadfast determination to persist in an effort over time, especially despite difficulties or delays. It emphasizes consistency and inner resolve rather than momentary enthusiasm.

This word is commonly used in motivational contexts — in education, self-improvement, sports training, or long-term goals like learning Chinese. Unlike the English word ‘perseverance,’ which can imply struggle against external obstacles, 恒心 carries a stronger sense of internal discipline and habitual commitment. It’s often paired with verbs like 有 (yǒu, ‘to have’), 缺乏 (quēfá, ‘to lack’), or 培养 (péiyǎng, ‘to cultivate’), and frequently appears in set phrases such as ‘要有恒心’ (‘You must have perseverance’) or ‘贵在恒心’ (‘What matters most is perseverance’).
