Yes and No in Thai: Natural Answers for Beginners
Learn how to say yes in Thai and no in Thai. Use ใช่ (châi), ไม่ (mâi), verb repetition and polite particles to answer questions naturally today.
Thai uses ใช่ (châi) for “correct” and ไม่ใช่ (mâi châi) for “not correct,” while many other yes or no answers repeat or negate the question’s main verb. Thai has no single word that works for every question, so the real skill is choosing the right response pattern. For more everyday language, see these useful Thai phrases.
Does Thai Have One Word for Yes?
No, Thai has no single universal yes; many questions are answered by repeating the main verb or adjective. When someone asks whether you want something, the natural answer is the verb “want,” not a separate word for yes.
The word ใช่ (châi) means “correct” or “that is right,” and it naturally answers confirmation questions such as ใช่ไหม (châi mái). It confirms that a statement is true rather than answering any question with a yes. Because ใช่ (châi) carries a tone, getting the pitch right matters; our guide to Thai tones explains how each tone changes meaning.
ใช่ (châi) and ไม่ใช่ (mâi châi) for Confirmation Questions
Use ใช่ (châi) when the question asks whether something is correct, and ไม่ใช่ (mâi châi) to deny an identity, statement or confirmation.
- Question: คุณเป็นคนอเมริกันใช่ไหม (khun bpen khon à-mee-rí-gan châi mái), “You are American, correct?”
- Answer: ใช่ครับ (châi khráp) if you are male, or ใช่ค่ะ (châi khâ) if you are female.
- Negative answer: ไม่ใช่ค่ะ (mâi châi khâ) or ไม่ใช่ครับ (mâi châi khráp), “that is not right.”
If the statement is true, answer ใช่ (châi). If it is not, answer ไม่ใช่ (mâi châi), which means “it is not” or “that is not right.” For a neutral university reference on these Thai response patterns, see the Northern Illinois University spoken Thai materials.
How to Answer ไหม (mái) Questions by Repeating the Verb
When a question ends in ไหม (mái), answer by repeating the main verb for yes or placing ไม่ (mâi) before it for no, except confirmation questions such as ใช่ไหม (châi mái), which are answered with ใช่ (châi) or ไม่ใช่ (mâi châi). The particle ไหม (mái) turns a statement into a yes or no question, and for most of these questions Thai answers by repeating the predicate rather than inserting a separate yes word.
Here is an ability question:
- Question: ได้ไหม (dâai mái), “Can I or may I?”
- Positive answer: ได้ (dâai), “you can.”
- Negative answer: ไม่ได้ (mâi dâai), “you cannot.”
And a preference question:
- Question: อยากไหม (yàak mái), “Do you want it?”
- Positive answer: อยาก (yàak), “I want it.”
- Negative answer: ไม่อยาก (mâi yàak), “I do not want it.”
The answer echoes the verb and adds ไม่ (mâi) for the negative version.
How to Say No in Thai with ไม่ (mâi)
To say no in Thai, place ไม่ (mâi) before the verb or adjective, and use ไม่ใช่ (mâi châi) when denying an identity, statement or confirmation.
The distinction is simple. ไม่ (mâi) negates an action or state, so ไม่เอา (mâi ao) means “I do not want it” when someone offers you something. ไม่ใช่ (mâi châi) denies a statement or identity, so it fits questions like ใช่ไหม (châi mái).
A quick comparison makes the boundary clear:
- Vendor asks: เอาไหม (ao mái), “Do you want it?”
- You answer: ไม่เอา (mâi ao), “I do not want it.”
- Vendor asks: นี่ของคุณใช่ไหม (nîi khǒng khun châi mái), “Is this yours?”
- You answer: ไม่ใช่ (mâi châi), “It is not.”
A Quick Table of Natural Short Answers
These 3 pairs are useful short answers for common preference, taking and ability questions, positive first and negative second. Each row pairs a common question verb with its positive and negative answer, with romanization in the same row so you can read it on a phone.
| Question verb | Positive answer | Negative answer |
|---|---|---|
| อยาก (yàak), “want” | อยาก (yàak) | ไม่อยาก (mâi yàak) |
| เอา (ao), “take or want it” | เอา (ao) | ไม่เอา (mâi ao) |
| ได้ (dâai), “can or may” | ได้ (dâai) | ไม่ได้ (mâi dâai) |
Listen for the main verb and choose the matching pair. For อยาก (yàak), answer อยาก (yàak) or ไม่อยาก (mâi yàak).
ยัง (yang): Answering Not Yet
Use ยัง (yang) for “not yet” when an expected action has not happened.
A common exchange at a food stall:
- Question: กินข้าวแล้วไหม (gin khâao láeo mái), “Have you eaten yet?”
- Answer: ยัง (yang), “not yet.”
ยัง (yang) tells the listener that the expected action has not happened yet.
Adding Polite Particles: ครับ (khráp), ค่ะ (khâ) and คะ (khá)
Add ครับ (khráp) if you are male and ค่ะ (khâ) if you are female to make a short answer polite, and use คะ (khá) when the answer itself is a question. These sentence-ending particles are common polite endings in Thai; they carry no meaning on their own, but they signal respect and soften what would otherwise sound abrupt.
The pattern is easy to apply:
- Male speaker: ใช่ครับ (châi khráp), “correct,” or ไม่เอาครับ (mâi ao khráp), “I do not want it.”
- Female speaker: ใช่ค่ะ (châi khâ), “correct,” or ไม่เอาค่ะ (mâi ao khâ), “I do not want it.”
- Female speaker asking in return: use คะ (khá) instead, because คะ (khá) ends questions while ค่ะ (khâ) ends statements.
Use the particle that matches the speaker when a polite ending is appropriate. Guided practice in our Thai language course in Bangkok can help you build the habit.
FAQ: Yes and No in Thai
Is ใช่ (châi) the same as yes in English?
No, ใช่ (châi) means “correct” or “that is right,” not a universal yes. It naturally answers confirmation questions such as ใช่ไหม (châi mái). For questions about wanting, taking or being able to do something, Thai repeats the main verb instead.
How do you say no in Thai with ไม่ (mâi)?
Place ไม่ (mâi) directly before the verb or adjective from the question, such as ไม่เอา (mâi ao) for “I do not want it.” Use ไม่ใช่ (mâi châi) when denying an identity, statement or confirmation, because it means “it is not” or “that is not right.”
Can you answer a ไหม (mái) question with ใช่ (châi)?
For most ไหม (mái) questions, natural Thai does not use ใช่ (châi). The answer repeats the predicate, such as ได้ (dâai) for “can,” or negates it with ไม่ (mâi), such as ไม่ได้ (mâi dâai) for “cannot.” The exception is the confirmation question ใช่ไหม (châi mái), which is answered with ใช่ (châi) or ไม่ใช่ (mâi châi), because ใช่ (châi) means “correct” rather than a general yes.
What is the difference between ค่ะ (khâ) and คะ (khá)?
ค่ะ (khâ) is a common female polite particle for statements, while คะ (khá) is the female polite particle used in questions. Male speakers commonly use ครับ (khráp) for both statements and questions. Choosing the right one keeps your short answers polite and clear when you speak with Thai people.
