……，对不对 / 好不好 (tag question with 不)

• 拼音: duì bu duì / hǎo bu hǎo
• 结构: Statement + ，对不对 / 好不好 / 是不是？
• 汉字拆解: 对 = 又 (again) + 寸 (inch)

含义

A statement followed by an A-not-A phrase like 对不对, 好不好, or 是不是 forms a tag question, asking for confirmation or agreement. It is similar to English 'right?' or 'okay?'.

Tag questions using the A-not-A structure are appended to statements to seek confirmation (对不对, 是不是) or agreement to a suggestion (好不好, 行不行). 对不对 and 是不是 are used when the speaker believes something is true and wants the listener to confirm: 你是北京人，对不对？(You're from Beijing, right?). 好不好 and 行不行 are used when proposing something: 我们走吧，好不好？(Let's go, okay?). These tags are softer and more polite than direct commands or bald statements. 是不是 can also be inserted into the middle of a sentence for emphasis: 你是不是忘了？(Did you forget?). The tone is usually rising on the tag, just like English tag questions.

例句

1. 这道题的答案是C，对不对？
2. 我们下课以后去吃饭，好不好？
3. 你昨天没来学校，是不是？

用法指南

正确说法

• 他说的是真的，对不对？
• 我们先把这个做完，好不好？
• 你已经见过她了，是不是？

错误说法

• 你是学生，对不对吗？(Do not add 吗 after a tag question — the A-not-A tag already functions as a question marker) → 你是学生，对不对？
• 明天放假，好不好不好？(Do not repeat the tag — one 好不好 is sufficient) → 明天放假，好不好？

起源与历史

Tag questions using A-not-A forms at the end of sentences developed as a natural extension of the broader A-not-A question pattern. They offer a less confrontational way to confirm information or seek agreement compared to direct questions.
