Week 1: Greetings & Politeness Particles
Goal
By the end of this lesson, you should be able to greet someone politely, choose the right ending particle for your speaker identity, and understand why Thai greetings are about relationship and respect — not just vocabulary.
Lesson 1 — Sawasdee (สวัสดี)
สวัสดี (sawasdee) is the standard Thai greeting. It can mean hello, goodbye, or good day depending on context.
| Thai script | Romanization | Meaning | Natural use |
|---|---|---|---|
| สวัสดีครับ | sawasdee khrap | Hello / goodbye | Male speaker, polite |
| สวัสดีค่ะ | sawasdee kha | Hello / goodbye | Female speaker, polite statement |
| สวัสดีครับ/ค่ะ | sawasdee khrap/kha | Hello | Safe default for shops, hotels, elders |
| สบายดีไหม | sabaai dii mai | How are you? | Friendly follow-up |
| สบายดี | sabaai dii | I am fine | Simple answer |
Practical tip: if you remember only one thing, say sawasdee + your politeness particle. That already sounds much better than using English only.
Cultural note — The wai (ไหว้)
The wai is the Thai greeting gesture: palms together, slight bow. It communicates respect, not just hello.
- Peers / casual situations: hands around chest or lower face
- Older people / teachers / respected people: hands closer to nose or forehead
- Monks / sacred places: hands higher, slower and more formal
You do not need to wai everyone first. In shops, restaurants, hotels, and casual modern settings, a smile plus sawasdee khrap/kha is often enough.
Lesson 2 — Politeness particles
Thai uses sentence-ending particles to show politeness and social warmth.
| Particle | Common user | Example | Meaning |
|---|---|---|---|
| ครับ | khrap | ขอบคุณครับ | Thank you, male speaker |
| ค่ะ | kha | ขอบคุณค่ะ | Thank you, female speaker statement |
| คะ | kha | ไปไหนคะ | Question particle, female speaker |
These particles are small, but they change the whole feeling of a sentence. Without them, beginners can sound too direct in formal situations.
