What a particle does
A polite particle goes at the very end of a sentence. It adds no dictionary meaning, but it tells the listener you are being courteous, and on its own it also works as "yes" or "I'm listening." Which one you use depends on your own gender and on how close you are to the person. Online you will often see them spelled krub, krap and ka. This page writes them khráp and khâ/khá to show the tones. No mark is a mid tone, a grave accent low, a circumflex falling, an acute high, and a háček rising. In relaxed speech many men say ครับ as kháp, with no r.
- Men: ครับ in statements and questions alike.
- Women: ค่ะ (falling) in statements and answers, คะ (high) in questions and after นะ.
- Anyone: นะ to soften, and จ้ะ, จ๊ะ or จ้า with people you are close to.
Kha or kha? Same sound, two tones
This is the pair learners mix up most. ค่ะ drops in pitch and closes a statement. คะ is high and marks a question. Listen to them back to back.
ขอบคุณค่ะ
Reading: khɔ̀ɔp-khun khâ
Meaning: Thank you.
Falling tone. Use it for thanks, answers, and plain statements.
ห้องน้ำอยู่ไหนคะ
Reading: hɔ̂ng-náam yùu nǎi khá
Meaning: Where is the restroom?
High tone, because it ends a question.
ค่ะ
Reading: khâ
Meaning: Yes. / Okay. / I'm listening.
On its own, the falling form is a polite yes. On the phone you will hear it repeated as the other person talks.
คะ
Reading: khá
Meaning: Sorry? / Yes?
Said alone with a questioning lift, it asks someone to repeat, or answers when someone calls you. A handy repair word.
ขอโทษนะคะ พูดอีกทีได้ไหมคะ
Reading: khɔ̌ɔ-thôot ná khá, phûut ìik thii dâai mái khá
Meaning: Excuse me, could you say that again?
The full repair line. Men say ขอโทษนะครับ พูดอีกทีได้ไหมครับ.
Khrap: one form for everything
Men do not switch tones. ครับ is the same at the end of a statement, a question, or a one-word answer.
สวัสดีครับ
Reading: sà-wàt-dii khráp
Meaning: Hello.
Careful speech keeps the r. Relaxed Bangkok speech sounds closer to sà-wàt-dii kháp.
ครับผม
Reading: khráp phǒm
Meaning: Yes, certainly.
An extra-polite yes for a boss, a teacher, a customer, or an older person. Service staff use it a lot.
ครับ
Reading: khráp
Meaning: Sorry? / Yes?
Like the women's high form, it asks someone to repeat when said with a questioning lift.
Na: soften it
Put นะ before the polite particle to make a request, a reminder, or a goodbye gentler, like adding "okay?" or "just" in English. After นะ, women always use the high form: นะคะ.
รอแป๊บนึงนะครับ
Reading: rɔɔ pɛ́p nʉng ná khráp
Meaning: Just a moment, please.
Polite and friendly. Without the softener it can sound like an order.
ไปก่อนนะคะ
Reading: pai gɔ̀ɔn ná khá
Meaning: I'm heading off now.
The everyday way to say goodbye when you leave first.
ไม่เป็นไรนะ
Reading: mâi pen rai ná
Meaning: It's fine, really. Don't worry.
Casual, with no polite particle. Use it with friends; add the polite particle for anyone older or a stranger.
Ja: close and warm
These sound affectionate. Parents use them with children, older people with younger ones, and friends with each other. Men and women both use them. จ้ะ falls in answers and จ๊ะ is high in questions, the same split as the women's polite pair.
จ้ะ
Reading: jâ
Meaning: Yes, dear. / Okay.
Falling tone. A soft yes to a child, a younger relative, or a close friend.
ไปไหนมาจ๊ะ
Reading: pai nǎi maa já
Meaning: Where have you been?
High tone in a question. Sounds caring, like an aunt greeting you.
ได้จ้า
Reading: dâai jâa
Meaning: Sure thing!
Stretched and cheerful. Very common with friends, in chat messages, and from friendly market vendors.
Stretched and casual versions
You will hear these all the time in Bangkok, even though textbooks rarely teach them.
ขอบคุณค่า
Reading: khɔ̀ɔp-khun khâa
Meaning: Thanks so much!
A longer, brighter version of the women's polite form. Friendly, used in shops, on the phone, and in chats.
ได้ฮะ
Reading: dâai há
Meaning: Sure.
A softer, more casual stand-in for ครับ, heard mostly from men, boys, and children talking to adults.
Switching particles in one visit
You, a woman, visit your Thai friend Ploy's family in Bangkok. You use polite particles with her mother, who answers you warmly, then drop them with Ploy.
Mother
มาแล้วเหรอจ๊ะ เข้ามาก่อนสิ
Reading: maa láew rə̌ə já, khâo maa gɔ̀ɔn sì
Meaning: Oh, you're here! Come on in.
You
สวัสดีค่ะ
Reading: sà-wàt-dii khâ
Meaning: Hello.
Mother
กินข้าวมาหรือยังจ๊ะ
Reading: gin khâao maa rʉ̌ʉ yang já
Meaning: Have you eaten yet?
You
ยังเลยค่ะ
Reading: yang loei khâ
Meaning: Not yet.
Mother
งั้นกินด้วยกันนะ เดี๋ยวแม่ทำให้

Meaning: Thank you. Sorry to put you to any trouble.
Ploy
มาแล้วเหรอ นั่งก่อนดิ

Meaning: Hey, you made it. Sit down.

Meaning: Of course, hang on a sec.

Meaning: Food's ready!

Who says what, and when
Your particle follows you, not the listener
Use the set that matches your own gender, whoever you are talking to. A man says ครับ to a woman, and a woman says ค่ะ to a man. Trans women use ค่ะ and คะ like other women, some gay men use them too, and some men use them playfully with friends. If you are non-binary, choose the set that feels right to you.
When you can drop them
With close friends your own age, people often use no polite particle at all, or switch to the warm ones. Keep the polite particles with strangers, elders, teachers, coworkers you don't know well, and anyone serving you. Leaving them off with an older person can sound curt, even if your words are kind.
You don't need one on every sentence
In a longer conversation, people add a particle to greetings, answers, requests, thanks, and the last sentence of what they say, not to every clause. Using it often is never rude. It just sounds extra polite.
In writing and chat messages
After นะ, the correct spelling is นะคะ. You will often see นะค่ะ online, but it is a common spelling mistake. Chat messages stretch particles for warmth, such as ค่า, จ้า and คร้าบ. Formal documents and news articles leave particles out.
Practice your particles in a real conversation
Particles stick when you use them without thinking about it. Set up a short scene where you need both statements and questions, then listen back for which ending you used.
- Open Create with AI and paste the description below. If you are a man, change the last two sentences to say you want to practice ending your sentences with khrap, and softening requests with na khrap.
- Talk out loud with the AI character, who replies by voice in Thai.
- After the conversation, read the full transcript and check the ending of every sentence you said, then look at the line with a clearer way to say it.
- Ask the AI Coach about any ending you were unsure of, then repeat the visit.
Describe it like this when you create the activity
Thai, beginner level, everyday Bangkok speech. I'm visiting a Thai friend's family home for dinner, and you play my friend's mother, who is warm, speaks to me with the friendly ja particles, and asks me lots of questions. I'm a woman and want to practice ending my answers and thanks with kha in the falling tone and my questions with kha in the high tone. I also want to soften requests and my goodbye with na kha.
Questions learners usually ask first
Can men say ค่ะ (khâ) in Thai?
Yes, some do. Some gay men use ค่ะ and คะ as their everyday polite particles, and some men say them jokingly with friends. Most men say ครับ, because people usually choose the particle that matches their own gender.
What does นะคะ (ná khá) mean?
It is two particles together: นะ softens the sentence, and คะ makes it polite for a woman speaker. Together they add a gentle "okay?" or "please," as in ไปก่อนนะคะ, I'm heading off now. The men's version is นะครับ.
Is it rude to forget ครับ or ค่ะ?
With friends your own age, no. With a stranger, an older person, or someone you just met, a sentence with no particle can sound abrupt. People are forgiving with learners, so add one when you remember, especially to thanks and answers.
How do you say yes politely in Thai?
Often the particle alone is the yes: ครับ for men, ค่ะ for women. For more warmth with someone close, use จ้ะ or จ้า. For an extra-respectful yes to a boss or customer, men say ครับผม.
