You can travel all of Thailand on English alone, but you shouldn’t want to. A handful of basic Thai phrases, delivered with a smile, genuinely changes your trip: warmer service, easier haggling, and the small delight on a vendor’s face when a foreigner says “thank you” in Thai. You don’t need fluency or perfect tones. You need about a dozen words and one golden rule of politeness. This guide is the hub for learning travel Thai, covering the politeness particles, greetings, food and market phrases, and directions, and it links out to deeper guides on the phrases people search for most.
Prices and phrases here are for orientation; Thai romanisation varies between sources, so treat the spellings below as pronunciation cues rather than a strict system. This is a practical companion to our city guides like the Bangkok street food guide and the Chiang Mai food tour, where you’ll actually put the words to use.
The one rule that matters most: khrap and kha
If you learn nothing else, learn this. Thai sentences are made polite by a gender-based particle at the end: men say “khrap” (often heard as “krup”) and women say “kha.” It has no direct English meaning, it simply signals respect, like a spoken bow. Attach it to anything, even a single word, and you sound courteous: “thank you khrap,” “hello kha.” Thais notice its presence and its absence instantly, so make it a habit and stick it on the end of every phrase below.
Essential Thai phrases for travellers
Start with these. The politeness particle (khrap/kha) is written as (m/f) where you’d add it.
| English | Thai (romanised) | When to use |
|---|---|---|
| Hello / goodbye | sawatdee (m/f) | Universal greeting, any time of day |
| Thank you | khop khun (m/f) | Always; add the particle for warmth |
| No worries / you’re welcome / it’s fine | mai pen rai | The most Thai phrase there is |
| Yes / correct | chai | Agreement |
| No / not | mai | Negation |
| Excuse me / sorry | kho thot (m/f) | Getting attention or apologising |
| How much? | thao rai | Shopping, taxis, markets |
| Delicious | aroy | A compliment cooks love |
| Not spicy | mai phet | If you’re heat-sensitive |
| The bill, please | kep ngoen / chek bin | Restaurants |
| Where is the toilet? | hong nam yu thi nai | Everywhere |
| I don’t understand | mai khao jai | When lost in conversation |
Romanisations are pronunciation cues; spellings vary by source.
How do you say hello and thank you?
Hello is “sawatdee” (sà-wàt-dii), with your particle: “sawatdee khrap” for men, “sawatdee kha” for women. It works morning, noon and night, and doubles as goodbye. Thank you is “khop khun”: “khop khun khrap” or “khop khun kha.” These two phrases plus a smile carry a huge share of daily interactions, checking into a hotel, buying street food, thanking a driver. For the full pronunciation, common variations and cultural notes, see our dedicated guides on how to say hello in Thai and how to say thank you in Thai.
Phrases for food and markets
This is where a little Thai pays off fastest. Compliment the cook with “aroy” (delicious). Ask the price with “thao rai?” Manage the chilli with “mai phet” (not spicy) or “phet nit noy” (a little spicy), Thai “a little spicy” can still surprise you. Close out with “kep ngoen” or “chek bin” (the bill, please). Knowing your numbers helps you understand prices and haggle; our Thai numbers guide breaks them down. Then put it all to work over a plate of northern Thai food or a night on the Bangkok street food trail.
The wai: Thailand’s greeting gesture
The wai, palms pressed together with a slight bow, is the traditional way to greet, thank and show respect, especially to elders and monks, one piece of the wider etiquette covered in our Thai culture and customs guide. The etiquette of who initiates and how high the hands go is genuinely subtle, and tourists aren’t expected to get it perfectly right. What’s appreciated is the effort: return a wai when one is offered, or offer a gentle one to an older person, and pair it with a smile. Don’t wai service staff for routine transactions (a nod and “khop khun” is plenty), but do return one graciously when greeted. For the fuller breakdown of when and how deep to wai, see our dedicated wai greeting guide.
Do you really need Thai to get by?
Honestly, no, and it’s worth being clear about that. In tourist areas, hotels, restaurants and on organised transport, enough English is spoken that you can travel comfortably without a word of Thai. The value of these phrases isn’t survival; it’s goodwill. Thais respond warmly to visitors who try, and a few polite words consistently earn friendlier service and smoother interactions. Learn the dozen phrases above, lean on the khrap/kha rule, and you’ll punch well above your actual language ability.
