Twenty Thai phrases that change how a family is treated.

Why twenty is the right number

Thai is a tonal language and it is genuinely difficult; the same syllable carries different meanings at different pitches, and a visitor will get the tones wrong. That does not matter here. What matters is the attempt, which in Thailand is received with real warmth rather than the polite embarrassment a bad accent earns in some countries. Twenty phrases cover greeting, thanks, apology, price, direction, food and emergency, which is the whole of daily life for a visiting family. Everything beyond that is a hobby.

The transliterations below are written to be read aloud by an Arabic or English speaker rather than to satisfy a linguist. Say them at a normal speaking volume, with a smile, and expect to be understood most of the time and gently corrected the rest. Being corrected is a good outcome: it is a Thai host taking you seriously enough to teach you.

The politeness particles: khrap and kha

This is the single most useful thing in the guide, so it comes before the list. Thai sentences are softened by a particle added at the end, and the particle depends on the sex of the speaker, not the person spoken to. A man ends the sentence with khrap, pronounced close to krup, with the r often dropped in speech. A woman ends it with kha, pronounced with a falling tone in a statement and a rising tone in a question, which is why you will hear both kha and khaa.

Used alone, khrap or kha means yes, I see, I am listening, or go on, and Thai staff use it constantly on the telephone. Attached to anything else, it converts a blunt instruction into a courteous request. Water becomes please may I have water. The same sentence without it is not rude exactly, but it lands flat, in roughly the way a request in English lands flat without please. If a visitor learns one syllable of Thai before landing, this is the one. Note also that men in the Gulf sometimes hesitate over kha because it sounds softer; the rule is fixed by the speaker's own sex, so a man says khrap in every situation, to everyone.

The twenty

Food, and the three phrases that carry weight

The dietary phrases are the ones worth practising until they come out cleanly. Mai sai mu, without pork, is understood everywhere and is a normal instruction in Thai kitchens rather than an exotic one; Thailand has a large Muslim population, particularly in the southern provinces, and Thai staff are broadly familiar with the requirement. Halal is a word Thai people know, and mi ahan halal mai will be answered honestly. Mai sai lao, without alcohol, is worth adding because rice wine and cooking alcohol appear in marinades and sauces where a diner would not expect them, and the question is rarely asked.

None of this replaces certification. Halal status in Thailand is granted per establishment by the Central Islamic Council of Thailand, not per chain, so a certified branch tells you nothing about the branch across the road. Look for the mark at the entrance or the counter. The phrases above manage the ordinary day; they are not a substitute for checking, and our guide to eating halal in Thailand covers the certification question properly.

Names, titles and how to address people

Thai people use first names, not family names, in almost every situation, and prefix them with khun, pronounced koon, as a respectful title for a man or a woman. Khun Somchai, khun Nok. Use it with hotel managers, doctors, drivers and business counterparts alike, and use it from the first meeting. Almost every Thai person also has a short nickname used by everybody including colleagues, often a single syllable, and being offered the nickname is a small sign of friendliness rather than informality; using it back is correct.

Two further courtesies travel well. Phi, pronounced pee, means older sibling and is used before a nickname for someone slightly senior in age or position; nong is its younger counterpart. Visitors do not need to deploy these, but recognising them explains a great deal of what you hear around you. And when thanking someone substantially, khop khun mak khrap, thank you very much, carries the extra weight the situation deserves.

Numbers, and the two you will actually use

Thai numerals are worth ten minutes for anyone who intends to shop in markets: nung, song, sam, si, ha, hok, jet, paet, kao, sip, for one to ten. Twenty is yi sip, one hundred is roi, one thousand is phan. The two constructions that matter in practice are the price question, tao rai, and the hundreds, because market prices for the things a family buys are almost always quoted in hundreds of baht. Song roi is two hundred. Ha roi is five hundred.

Bargaining is normal in markets and completely abnormal in malls, hotels and hospitals, where prices are fixed and an attempt to negotiate causes quiet awkwardness. In a market, one round of phaeng pai and lot noi dai mai, delivered with good humour, is the whole ritual; a hard negotiation over a small sum is read as unpleasant rather than shrewd. Both cultures understand the difference between a bazaar and a shop, so this is not new ground, only a note on where the line falls in Thailand.

How our office teaches this to a household

For families arriving with staff, we put the twenty phrases on a single printed card in Arabic, English and transliterated Thai, and give one to every adult and every driver on the first morning. Children take to it faster than anybody and become the household's translators within a week, which is worth encouraging. We also write the family's dietary requirements in Thai script on a card that can be handed across a counter, and the address of the residence in Thai script for the reverse, which solves the two situations where a phrase list is not enough.

Transliteration cannot capture Thai tones, and a phrase list is a courtesy rather than a translation service. For anything medical, legal or financial, use a professional interpreter. For dietary certainty, verify halal status per outlet with the Central Islamic Council of Thailand at halal.or.th rather than relying on a spoken assurance, and confirm any written Thai script card with a native speaker before you rely on it.

This briefing is general information, not legal, tax or investment advice. Thai rules change frequently and individual cases differ. Verify current requirements with the relevant authorities, including the Immigration Bureau, the Board of Investment, the Land Department, the Department of Business Development and the Revenue Department, and take advice on your own facts before acting.
