不成

• 拼音: bù chéng
• 汉字拆解: 不 = negative particle; 成 = 戈 (weapon) + 丁 (nail/man) — originally 'to complete'

含义

Won't do; won't work; unacceptable; used after a verb to indicate inability or failure to achieve a result.

Functions both as a verb complement indicating failure and as an adjective meaning inadequate or unacceptable. Often appears at the end of a sentence as a rhetorical question particle, similar to 'isn't it?' In colloquial speech, adds emphasis to disbelief or incredulity.
