Good Morning in Thai: The Natural Phrase, Script and Polite Particles
Learn the natural way to say good morning in Thai, with Thai script, polite particles, approximate pronunciation, formal alternatives and good night.
The natural way to say good morning in Thai is สวัสดีครับ (sawatdee khrap) for a male speaker or สวัสดีค่ะ (sawatdee kha) for a female speaker. When you are learning good morning in Thai, the useful surprise is that Thai does not have a special everyday morning phrase. Thai speakers use the same all-purpose greeting at any time of day, and the polite ending depends on you, the speaker, not the person you are greeting.
Thai does have a literal morning phrase, สวัสดีตอนเช้า (sawatdee ton chao), and a formal or poetic one, อรุณสวัสดิ์ (arun sawat). This page covers both, explains the polite particles, and ends with a short good night phrase so you can greet people from morning to bedtime.
The Everyday Morning Greeting: สวัสดีครับ (sawatdee khrap) or สวัสดีค่ะ (sawatdee kha)
For an everyday morning greeting, Thai speakers commonly use สวัสดี (sawatdee) with a polite particle rather than a time-specific equivalent of good morning. This is the everyday form, and it is the one beginners should learn first.
The phrase has 2 parts. สวัสดี (sawatdee) is the standard Thai greeting, used at any time of day. The second part is the polite particle, ครับ (khrap) for a male speaker or ค่ะ (kha) for a female speaker, which makes the greeting polite.
Romanization here is only approximate, because Thai is a tonal language and English letters cannot fully capture the sounds.
That is why we recommend checking pronunciation with audio or a certified teacher rather than relying on romanization alone. If you want more everyday expressions, see our collection of Thai phrases to know for greetings, questions and polite essentials.
Polite Particles: ครับ (khrap) for Male Speakers, ค่ะ (kha) for Female Speakers
The standard polite form is สวัสดีครับ (sawatdee khrap) for a male speaker and สวัสดีค่ะ (sawatdee kha) for a female speaker, because the particle follows the speaker’s identity in standard beginner Thai teaching. This is the point where most beginners hesitate, because many people assume the particle depends on who they are talking to. It does not. You choose the particle that matches you.
| Speaker | Thai particle | Approximate romanization |
|---|---|---|
| Male speaker | ครับ | khrap |
| Female speaker | ค่ะ | kha |
A man says สวัสดีครับ (sawatdee khrap), and a woman says สวัสดีค่ะ (sawatdee kha). The particle makes your greeting polite, and it follows the standard beginner convention of matching the speaker.
Remember the caveat from earlier: khrap and kha are approximate English renderings. Thai pronunciation is best learned with audio or a certified teacher.
The Literal Phrase: สวัสดีตอนเช้า (sawatdee ton chao)
สวัสดีตอนเช้า (sawatdee ton chao) is a literal, time-specific way to say good morning. You will meet it in dictionaries and phrase lists, so it is worth recognising even if you rarely lead with it.
The build is simple. It takes the familiar greeting สวัสดี (sawatdee) and adds ตอนเช้า (ton chao), which refers to the morning period. The result is a direct Thai equivalent of the English phrase “good morning”, assembled word by word.
In practice, the plain สวัสดี (sawatdee) forms are the everyday choice in morning conversation, so recognising สวัสดีตอนเช้า (sawatdee ton chao) matters more than using it. If someone greets you with it, you will know exactly what they mean.
The Formal Phrase: อรุณสวัสดิ์ (arun sawat)
อรุณสวัสดิ์ (arun sawat) is a formal or poetic good-morning expression that is uncommon in ordinary conversation.
So why do you keep finding it first? Because bilingual dictionaries give it as a direct translation. The Cambridge English-Thai Dictionary lists อรุณสวัสดิ์ (arun sawat) for good morning, which is why so many searchers meet it before the everyday greeting.
The practical rule for beginners: use สวัสดีครับ (sawatdee khrap) or สวัสดีค่ะ (sawatdee kha) in conversation, and treat อรุณสวัสดิ์ (arun sawat) as a phrase to recognise rather than one to lead with.
How to Say Good Night in Thai: ฝันดี (fan dee)
To say good night in Thai, use ฝันดี (fan dee), which literally expresses a wish for good dreams and is a natural phrase before sleep. It pairs with the same polite particles you already know: a man says ฝันดีครับ (fan dee khrap) and a woman says ฝันดีค่ะ (fan dee kha).
There is one contrast worth remembering. Good morning in everyday Thai uses the all-purpose greeting, while good night uses a phrase that is time-specific in normal use. So the morning question and the bedtime question have opposite answers, which is why beginners often mix them up.

FAQ
Is อรุณสวัสดิ์ (arun sawat) the correct way to say good morning in Thai?
อรุณสวัสดิ์ (arun sawat) is a formal or poetic good-morning expression, but it is uncommon in ordinary conversation, so it is not the everyday answer to the question. It appears first in many results because dictionaries such as the Cambridge English-Thai Dictionary list it as a direct translation of good morning. For daily use, สวัสดี (sawatdee) with a polite particle is the natural choice.
Should I say khrap or kha?
The standard polite form is สวัสดีครับ (sawatdee khrap) for a male speaker and สวัสดีค่ะ (sawatdee kha) for a female speaker. The particle follows the speaker’s identity in standard beginner Thai teaching, so you pick the one that matches you, not your listener.
Can I use สวัสดี (sawatdee) at any time of day?
Yes. Thai speakers commonly use สวัสดี (sawatdee) with a polite particle at any time, including mornings, which is why it works as the natural good morning greeting. The same สวัสดีครับ (sawatdee khrap) or สวัสดีค่ะ (sawatdee kha) serves you at breakfast, midday and evening. This is one of the features that makes Thai greetings simple for beginners to start with.
What is the difference between สวัสดีตอนเช้า (sawatdee ton chao) and สวัสดี (sawatdee)?
สวัสดีตอนเช้า (sawatdee ton chao) is the literal, time-specific way to say good morning, built from the greeting สวัสดี (sawatdee) plus ตอนเช้า (ton chao) meaning the morning period. Plain สวัสดีครับ (sawatdee khrap) and สวัสดีค่ะ (sawatdee kha) are the everyday forms used in actual morning conversation. Recognising the literal phrase is useful, because the plain forms are the everyday choice.
How do I say good night in Thai?
Use ฝันดี (fan dee), which literally expresses a wish for good dreams and is a natural phrase before sleep. Add the polite particle that matches you: ฝันดีครับ (fan dee khrap) for a male speaker or ฝันดีค่ะ (fan dee kha) for a female speaker. Unlike the morning greeting, this phrase is time-specific, so save it for bedtime.
