“Hello” in Thai: 9 Ways to Greet Someone in Thai

---

Do you want to learn how to greet someone in Thai?

Saying “hello” in Thai respectfully involves more than learning the familiar phrase สวัสดี (sa-wat-dii). The greeting you choose depends on who you’re speaking with and the situation.

This guide gives you nine useful Thai greetings, along with the register, simple pronunciation and natural replies you need to use them well.

Quick List: 4 Common Greetings in Thai

Start with these four common greetings:

• สวัสดีครับ/ค่ะ (sa-wat-dii khrap/kha) – polite “hello”
• หวัดดีครับ/ค่ะ (wat-dii khrap/kha) – casual “hello”
• สบายดีไหมครับ/คะ (sa-baai dii mai khrap/kha) – polite “How are you?”
• เป็นไงบ้าง (bpen ngai baang) – casual “How are you?” or “What’s up?”

How to Say “Hello” in Thai

Thai greetings signal both warmth and respect. Your relationship with the listener matters, so it helps to recognise two broad registers: polite and casual.

Polite language is the sensible starting point with strangers, older people and anyone you’re meeting in a professional or formal setting. Casual forms suit friends, family and people who have invited a more relaxed tone. Thai also has specialised royal vocabulary, but you won’t need it for everyday greetings.

Thai has five tones, and its sounds are represented in English using several romanisation systems. The spellings below are learner-friendly approximations. Use them as prompts, then check the sounds with native audio and our guide to reading Thai and its tones.

Polite Ending Particles

Thai speakers often add a sentence-final particle to make a greeting, statement or question polite. Male speakers generally use ครับ (khrap). Female speakers generally use ค่ะ (kha, with a falling tone) after statements and คะ (kha, with a high tone) after questions or requests. The Thai spellings show a difference that the simple romanisation does not.

These particles add respect without changing the core message. Friends may leave them out in relaxed conversation, while learners can use them to set a courteous tone. The Thailand Foundation’s guide to ครับ and ค่ะ explains the distinction in more detail, and our guide to saying “thank you” in Thai shows the particles in more examples.

How to Say a Polite “Hello” in Thai – สวัสดีครับ/ค่ะ (Sa-wat-dii Khrap/Kha)

สวัสดีครับ/ค่ะ (sa-wat-dii khrap/kha) is the standard polite way to say “hello” in Thai. It works at any time of day and is a good choice when you meet someone for the first time.

The core greeting สวัสดี (sa-wat-dii) can stand on its own, especially in casual speech. Adding ครับ or ค่ะ makes your greeting more courteous. สวัสดี can also be used when saying goodbye.

How to Say a Casual “Hello” in Thai – หวัดดีครับ/ค่ะ (Wat-dii Khrap/Kha)

หวัดดี (wat-dii) is a shortened, colloquial form of สวัสดี. Use it with friends and people you know well. Adding ครับ or ค่ะ softens it, but the shortened greeting still sounds more casual than the full form.

How to Say a Formal “Good Morning” in Thai – อรุณสวัสดิ์ (A-run Sa-wat)

อรุณสวัสดิ์ (a-run sa-wat) means “good morning”, but it sounds formal or literary and is uncommon in everyday conversation. You’re more likely to hear it in a broadcast or ceremonial setting.

In an ordinary morning conversation, สวัสดีครับ/ค่ะ (sa-wat-dii khrap/kha) is more natural. You may also hear สวัสดีตอนเช้าครับ/ค่ะ (sa-wat-dii dton chao khrap/kha), literally “hello in the morning”.

How to Say a Polite “How Are You?” in Thai – สบายดีไหม (Sa-baai Dii Mai)

สบายดีไหม (sa-baai dii mai) asks whether someone is well. To make the question explicitly polite, say สบายดีไหมครับ (sa-baai dii mai khrap) as a male speaker or สบายดีไหมคะ (sa-baai dii mai kha) as a female speaker.

A common positive reply is สบายดีครับ/ค่ะ (sa-baai dii khrap/kha), “I’m well.” ไม่สบายครับ/ค่ะ (mai sa-baai khrap/kha) means “I’m unwell.”

How to Say a Casual “How Are You?” in Thai – เป็นไงบ้าง (Bpen Ngai Baang)

With someone you know, เป็นไงบ้าง (bpen ngai baang) is a natural way to ask “How are things?” or “What’s up?” It is a conversational contraction of เป็นอย่างไรบ้าง (bpen yaang rai baang).

Keep this version for friends and relaxed situations. With a new acquaintance or in a formal setting, use สบายดีไหมครับ/คะ instead.

A Caring, Informal Thai Greeting – กินข้าวหรือยัง (Gin Khao Rue Yang)

กินข้าวหรือยัง (gin khao rue yang) literally asks, “Have you eaten yet?” In a familiar context, it can also work as a caring check-in rather than a request for a detailed account of your last meal.

You can reply กินแล้ว (gin laeo), “I’ve eaten already,” or ยัง (yang), “not yet.” Add ครับ or คะ to the question, and ครับ or ค่ะ to the answer, when you want to sound more polite.

A Common Thai Phatic Question – ไปไหน (Bpai Nai)

If you are on the move, someone you know may ask ไปไหน (bpai nai), literally “Where are you going?” In context, it can be a brief, friendly acknowledgement rather than a demand for your itinerary.

A short answer is enough: กลับบ้าน (glap baan), “going home”, or ไปตลาด (bpai dta-laat), “going to the market”. The bare question is casual. ไปไหนครับ/คะ (bpai nai khrap/kha) adds a polite ending, although the question may still feel personal if you use it with a stranger.

How to Say “Nice to Meet You” in Thai – ยินดีที่ได้รู้จัก (Yin-dii Thii Dai Ruu-jak)

When you meet someone for the first time, say ยินดีที่ได้รู้จักครับ/ค่ะ (yin-dii thii dai ruu-jak khrap/kha), “Nice to meet you.” The polite particle is especially helpful in a first introduction.

ยินดีที่ได้เจอกันอีกครับ/ค่ะ (yin-dii thii dai joe gan iik khrap/kha) means “It’s nice to see you again.”

How to Introduce Your Name in Thai – ชื่อ (Chue)

After your greeting, you can introduce yourself with ชื่อ [name] ครับ/ค่ะ (chue [name] khrap/kha). Thai often drops a pronoun when the speaker is clear from context.

For a full sentence, a male speaker can say ผมชื่อ [name] ครับ (phom chue [name] khrap), while a female speaker can say ฉันชื่อ [name] ค่ะ (chan chue [name] kha). To ask someone’s name politely, use ชื่ออะไรครับ/คะ (chue a-rai khrap/kha), “What is your name?”

How to Use the ไหว้ (Wai) Gesture

The ไหว้ (wai) is a gesture of respect made with the palms together, often accompanied by a slight bow. It can accompany สวัสดีครับ/ค่ะ, but it is more than a general-purpose “hello” gesture.

For a light-hearted example, see how the gesture appears in everyday Bangkok in this post from @languagehacking.

As a broad rule, the younger or more junior person initiates the wai, and the older or more senior person acknowledges or returns it. You don’t generally need to initiate a wai with close friends, and customers are not expected to return every wai offered by service staff. If someone greets you with a wai and you’re unsure, a smile and a polite สวัสดีครับ/ค่ะ are respectful responses.

Hand height reflects the level of respect. Thailand’s Public Relations Department describes three main levels: around the chin for a general wai, around the nose for parents, teachers and elders, and around the forehead for monks or sacred images. As a visitor, follow the other person’s lead rather than trying to perform the most formal version by default.

Choose two greetings from this list and say them aloud until they feel comfortable. If you want a plan for taking phrases like these into a real first chat, Conversation Countdown gives you a practical next step.
