Thai has words translated as “yes,” but ordinary polar answers often repeat the questioned predicate: ไปไหม — ไป “Are you going? — Yes,” มีไหม — มี, ได้ไหม — ได้. A negative answer places ไม่ before that predicate or uses its conventional negative form. This preserves exactly what is being confirmed or denied.
Start with the question forms on ไหม polar questions; this page focuses on how the response retrieves their predicate.
Repeat the predicate
The answer selects the semantic center of the question, not a universal auxiliary. Pronouns and objects disappear when the question has already established them.
| Question center | Positive answer | Negative answer |
|---|---|---|
| ไปไหม | ไป | ไม่ไป |
| มีไหม | มี | ไม่มี |
| เป็นไหม | เป็น | ไม่เป็น |
| ได้ไหม | ได้ | ไม่ได้ |
| เสร็จหรือยัง | เสร็จแล้ว | ยัง |
พรุ่งนี้ไปประชุมไหมคะ — ไปครับ
phrung ni pai prachum mai kha pai khrap
Are you going to the meeting tomorrow? — Yes. (ordinary polite exchange; predicate repeated by male respondent)
ร้านนี้มีอาหารมังสวิรัติไหมครับ — มีค่ะ
ran ni mi ahan mangsawirat mai khrap mi kha
Does this restaurant have vegetarian food? — Yes. (ordinary polite exchange; female respondent)
ขับรถเกียร์ธรรมดาเป็นไหมคะ — ไม่เป็นครับ
khap rot kia thammada pen mai kha mai pen khrap
Do you know how to drive a manual car? — No. (ordinary polite exchange; learned ability denied)
Predicate repetition answers the proposition while avoiding English do-support. Thai never needs an equivalent of “Yes, I do” merely because the question contains an action verb.
ใช่ confirms identity or a presented proposition
ใช่ is natural when the question asks whether an identity/equation is correct or uses ใช่ไหม to seek confirmation. It is not the best automatic answer to every ไหม question.
คุณเป็นคนจองห้องใช่ไหมคะ — ใช่ครับ
khun pen khon chong hong chai mai kha chai khrap
You're the person who booked the room, right? — That's right. (ordinary polite confirmation)
คุณพักที่นี่ไหมคะ — พักครับ
khun phak thi ni mai kha phak khrap
Are you staying here? — Yes. (ordinary polite exchange; predicate answer is more direct than generic ใช่)
For a negative confirmation question, ใช่ confirms the whole negative proposition:
คุณไม่กินเนื้อใช่ไหมคะ — ใช่ครับ ไม่กิน
khun mai kin nuea chai mai kha chai khrap mai kin
You don't eat meat, right? — Correct, I don't. (ordinary polite confirmation of a negative proposition)
An English speaker may hear “yes” and infer positive meat-eating. The repeated ไม่กิน removes that ambiguity.
Aspect and modality belong in the answer
หรือยัง asks whether a threshold has been reached. Positive answers normally use แล้ว; negative ยัง means “not yet” in this response slot. Ability/permission questions with ได้ไหม answer ได้/ไม่ได้, but a follow-up can identify whether the issue was ability, permission, or feasibility.
ส่งรายงานแล้วหรือยังคะ — ส่งแล้วครับ
song raingan laeo rue yang kha song laeo khrap
Have you sent the report yet? — Yes, I have. (ordinary polite exchange, male respondent)
ชำระเงินวันนี้ได้ไหมครับ — ยังไม่ได้ค่ะ ระบบปิดปรับปรุงอยู่
chamra ngoen wan ni dai mai khrap yang mai dai kha rabop pit prapprung yu
Can I pay today? — Not yet; the system is undergoing maintenance. (ordinary polite service exchange, female respondent)
The answer does not conjugate. แล้ว, ยัง, time phrases, and context locate the event.
The same answer in three stances
The proposition is “I can finish today.”
ได้
dai
Yes, I can. (informal or task-focused answer)
ได้ครับ
dai khrap
Yes, I can. (ordinary polite answer, male speaker)
น่าจะได้ครับ แต่ขอตรวจข้อมูลอีกครั้งก่อน
na cha dai khrap tae kho truat khomun ik khrang kon
I should be able to, but let me check the data once more. (carefully qualified polite answer, male speaker)
The third is not a full yes. น่าจะ lowers certainty and the following clause delays commitment. Relationship and consequences determine whether a bare ได้ is adequately informative.
Particle-stack contrast and intonation
ได้
dai
Yes / possible. (bare task-focused response)
ได้ครับ
dai khrap
Yes. (ordinary polite male response)
ได้เลยครับ
dai loei khrap
Absolutely / certainly. (enthusiastic or service-ready polite response, male speaker)
ได้นะครับ
dai na khrap
It is possible, you know / that is acceptable. (polite reassuring response, male speaker)
เลย strengthens readiness; นะ presents the answer for alignment or reassurance. A crisp falling ได้ครับ sounds decisive. A stretched ได้...ครับ may signal hesitation despite the same words. Intonation changes confidence and stance, not the predicate’s core meaning.
Silence after a polar question is not “no” by grammar. It can signal hesitation, deference, trouble, or refusal avoidance. Seek clarification rather than assigning polarity.
Ordinary-polite dialogue
พรุ่งนี้ส่งฉบับแก้ไขได้ไหมคะ
phrung ni song chabap kaekhai dai mai kha
Can you send the revised version tomorrow? (ordinary polite question, female speaker)
ได้ครับ แต่คงส่งช่วงบ่าย
dai khrap tae khong song chuang bai
Yes, but it will probably be in the afternoon. (ordinary polite qualified answer, male speaker)
ก่อนสามโมงได้ไหมคะ
kon sam mong dai mai kha
Could it be before three? (ordinary polite follow-up, female speaker)
น่าจะได้ครับ ถ้าเสร็จแล้วจะส่งทันที
na cha dai khrap tha set laeo cha song thanthi
I should be able to. Once it is finished, I'll send it immediately. (ordinary polite qualified commitment, male speaker)
Common Mistakes
1. Answering with an unrelated predicate
❌ ไปตลาดไหมคะ — เป็นครับ
Incorrect—เป็น does not answer the action predicate ไป.
✅ ไปตลาดไหมคะ — ไปครับ
pai talat mai kha pai khrap
Are you going to the market? — Yes. (ordinary polite exchange)
2. Copying English do-support
❌ คุณชอบกาแฟไหมคะ — ทำครับ
Incorrect—Thai repeats ชอบ, not an English-style auxiliary ‘do.’
✅ คุณชอบกาแฟไหมคะ — ชอบครับ
khun chop kafae mai kha chop khrap
Do you like coffee? — Yes. (ordinary polite exchange)
3. Giving ambiguous yes to a negative confirmation
❌ คุณไม่รับถุงใช่ไหมคะ — ใช่ครับ
Potentially unclear to an English-speaking interlocutor because the negative proposition is not repeated.
✅ คุณไม่รับถุงใช่ไหมคะ — ใช่ครับ ไม่รับครับ
khun mai rap thung chai mai kha chai khrap mai rap khrap
You don't want a bag, right? — Correct, I don't. (ordinary polite explicit confirmation)
4. Using แล้ว for “not yet”
❌ กินข้าวแล้วหรือยังคะ — แล้วไม่ครับ
Incorrect negative response to a threshold question.
✅ กินข้าวแล้วหรือยังคะ — ยังครับ
kin khao laeo rue yang kha yang khrap
Have you eaten yet? — Not yet. (ordinary polite exchange)
Key Takeaways
- Repeat or negate the questioned predicate: ไป/ไม่ไป, มี/ไม่มี, ได้/ไม่ได้.
- ใช่ confirms identity or a presented proposition; it is not universal English “yes.”
- Preserve aspect and modality in the answer, especially แล้ว/ยัง and qualified น่าจะได้.
- Particles and intonation mark politeness, readiness, certainty, and alignment; silence has no fixed polarity.
