要不

• Pinyin: yào bù
• Desglose de hanzi: 要 = 西 (cover) + 女 (woman — original meaning: to demand/require; extended to 'must/if'); 不 = root-downward pictograph (negation)

Significado

Si no; de lo contrario; o si no (como alternativa).

Functions as a conjunction linking two clauses: (1) 'otherwise / or else' — presenting a negative consequence if the preceding condition is not met; (2) 'how about / alternatively' — suggesting an alternative option in a proposal. Common in spoken and informal written Chinese.

Correcto

• 你现在就得把合同签了，要不对方随时可能变卦，到那时候再后悔也来不及了。(You need to sign the contract right now; otherwise the other party could change their mind at any moment, and by then it will be too late to regret it.)
• 这个方案目前看来确实存在一些不足，要不我们今天先搁置争议，各自回去再完善一下，明天再继续讨论？(This plan does have some shortcomings at the moment; how about we set aside the dispute for today, each go back and refine our ideas, and then continue the discussion tomorrow?)

Incorrecto

• 要不然而如此 — 要不 is a standalone conjunction; do not combine with 然而 or 如此; say 要不然 or simply 要不; stacking conjunctions is grammatically redundant and unnatural
