How To Ask Simple Questions In Thai

Introduction

Knowing how to ask for information is one of the most useful parts of learning a new language. Questions help you find places, order food, understand prices, meet people, arrange transport, and solve everyday problems.

Fortunately, beginners can ask questions in Thai using a small number of clear patterns. Thai verbs do not normally change, and many questions are created simply by adding a question word or a question particle to an ordinary sentence.

For example:

คุณชอบกาแฟ
Khun chop kafae.
You like coffee.

Add ไหม — mai at the end:

คุณชอบกาแฟไหมครับ
Khun chop kafae mai khrap?
Do you like coffee?

Other useful question words include arai for what, thi nai for where, khrai for who, thao rai for how much, and muea rai for when.

This guide explains how to ask questions in Thai using Thai script, clear romanisation, polite endings, everyday examples, and reusable sentence patterns.

👉 “Readers practicing everyday Thai questions may also explore local festivals and events across Asia for more cultural experiences and conversation ideas.”

Thai Questions Are Often Easier Than English Questions

English questions may require changes in word order:

• You like coffee.
• Do you like coffee?
• He is coming.
• Is he coming?

Thai usually keeps the original sentence order.

Statement:

เขาจะมา
Khao cha ma.
He or she will come.

Question:

เขาจะมาไหม
Khao cha ma mai?
Will he or she come?

The main sentence stays the same. The word mai is added at the end.

This makes it easier to ask questions in Thai without learning many special verb forms.

Add Polite Particles

Thai questions often end with a polite particle.

Male speakers commonly use:

ครับ — khrap

Female speakers commonly use:

คะ — kha

Examples:

คุณชื่ออะไรครับ
Khun chue arai khrap?
What is your name? Said by a man.

ห้องน้ำอยู่ที่ไหนคะ
Hong nam yu thi nai kha?
Where is the toilet? Said by a woman.

The polite particle depends mainly on the speaker, not the listener.

A male speaker generally uses khrap, while a female speaker generally uses kha.

Adding these endings helps beginners ask questions in Thai politely, especially with strangers, older people, service workers, teachers, and colleagues.

Forming Yes-Or-No Questions With Mai

The most common beginner pattern is:

Statement + mai?

The word:

ไหม — mai — yes-or-no question particle

is placed near the end of the sentence.

Examples:

คุณชอบอาหารไทยไหมครับ
Khun chop ahaan Thai mai khrap?
Do you like Thai food?

อาหารเผ็ดไหมคะ
Ahaan phet mai kha?
Is the food spicy?

ไปด้วยกันไหม
Pai duai kan mai?
Shall we go together?

พูดภาษาอังกฤษได้ไหมครับ
Phut phasa Angkrit dai mai khrap?
Can you speak English?

This is one of the easiest ways to ask questions in Thai because the normal word order does not change.

How To Answer Mai Questions

Thai commonly answers a yes-or-no question by repeating the important verb or adjective.

Question:

ชอบไหม
Chop mai?
Do you like it?

Positive answer:

ชอบ
Chop.
Yes, I like it.

Negative answer:

ไม่ชอบ
Mai chop.
No, I do not like it.

Another example:

แพงไหม
Phaeng mai?
Is it expensive?

แพง
Phaeng.
Yes, it is expensive.

ไม่แพง
Mai phaeng.
No, it is not expensive.

Thai does have words that can mean yes, but repeating the verb or adjective often sounds more natural.

Ask “What?” With Arai

The word:

อะไร — arai — what

usually appears in the part of the sentence where the missing information belongs.

Examples:

นี่อะไรครับ
Ni arai khrap?
What is this?

คุณชื่ออะไรคะ
Khun chue arai kha?
What is your name?

คุณกินอะไรครับ
Khun kin arai khrap?
What are you eating?

อยากได้อะไรคะ
Yak dai arai kha?
What would you like?

When you ask questions in Thai, do not automatically move arai to the beginning as you might move “what” in English.

Statement:

คุณกินข้าว
Khun kin khao.
You eat rice.

Replace the object with arai:

คุณกินอะไร
Khun kin arai?
What do you eat?

Ask “Where?” With Thi Nai

The common expression is:

ที่ไหน — thi nai — where

Examples:

ห้องน้ำอยู่ที่ไหนครับ
Hong nam yu thi nai khrap?
Where is the toilet?

คุณพักที่ไหนคะ
Khun phak thi nai kha?
Where are you staying?

ร้านอาหารอยู่ที่ไหนครับ
Ran ahaan yu thi nai khrap?
Where is the restaurant?

In casual speech, thi is often omitted:

ไปไหนครับ
Pai nai khrap?
Where are you going?

อยู่ไหนคะ
Yu nai kha?
Where is it?
Where are you?

Both forms are useful when learning to ask questions in Thai.

Ask “Who?” With Khrai

The word:

ใคร — khrai — who

can refer to the subject or another person in the sentence.

Examples:

เขาเป็นใครครับ
Khao pen khrai khrap?
Who is he or she?

ใครมาคะ
Khrai ma kha?
Who is coming?

คุณไปกับใครครับ
Khun pai kap khrai khrap?
Who are you going with?

นี่ของใครคะ
Ni khong khrai kha?
Whose is this?

The word khrai stays where the unknown person belongs.

This pattern helps beginners ask questions in Thai without changing the whole sentence.

Ask “When?” With Muea Rai

The word:

เมื่อไหร่ — muea rai — when

usually appears near the end of the sentence.

Examples:

คุณจะไปเมื่อไหร่ครับ
Khun cha pai muea rai khrap?
When will you go?

เขาจะมาเมื่อไหร่คะ
Khao cha ma muea rai kha?
When will he or she come?

ร้านเปิดเมื่อไหร่ครับ
Ran poet muea rai khrap?
When does the shop open?

คุณกลับเมื่อไหร่คะ
Khun klap muea rai kha?
When will you return?

Thai speakers may also ask a more specific time question using ki mong, meaning what time.

Ask “What Time?” With Ki Mong

The expression:

กี่โมง — ki mong — what time

is used for clock time.

Examples:

ตอนนี้กี่โมงครับ
Ton ni ki mong khrap?
What time is it now?

ร้านเปิดกี่โมงคะ
Ran poet ki mong kha?
What time does the shop open?

รถออกกี่โมงครับ
Rot ok ki mong khrap?
What time does the vehicle leave?

คุณจะมากี่โมงคะ
Khun cha ma ki mong kha?
What time will you come?

This is an essential pattern for travel, appointments, and daily routines.

Ask “Why?” With Thammai

The word:

ทำไม — thammai — why

often appears near the beginning of a question.

Examples:

ทำไมคุณเรียนภาษาไทยครับ
Thammai khun rian phasa Thai khrap?
Why are you learning Thai?

ทำไมเขาไม่มาคะ
Thammai khao mai ma kha?
Why is he or she not coming?

ทำไมร้านปิดครับ
Thammai ran pit khrap?
Why is the shop closed?

ทำไมแพงจังคะ
Thammai phaeng jang kha?
Why is it so expensive?

When you ask questions in Thai with thammai, remember that tone and politeness matter. A direct “why?” can sound challenging in some situations, just as it can in English.

Ask “How?” With Yang Ngai

The common spoken expression is:

ยังไง — yang ngai — how

A more formal written form is:

อย่างไร — yang rai — how

Everyday examples:

ไปยังไงครับ
Pai yang ngai khrap?
How do I get there?

ทำยังไงคะ
Tham yang ngai kha?
How do I do it?

พูดภาษาไทยว่ายังไงครับ
Phut phasa Thai wa yang ngai khrap?
How do you say it in Thai?

ใช้ยังไงคะ
Chai yang ngai kha?
How do you use it?

Yang ngai is extremely useful for beginners who need instructions or directions.

Ask “How Much?” With Thao Rai

The expression:

เท่าไหร่ — thao rai — how much

is essential for shopping, taxis, restaurants, and services.

Examples:

อันนี้เท่าไหร่ครับ
An ni thao rai khrap?
How much is this?

ทั้งหมดเท่าไหร่คะ
Thang mot thao rai kha?
How much is everything?

ค่าแท็กซี่เท่าไหร่ครับ
Kha taxi thao rai khrap?
How much is the taxi fare?

ห้องนี้คืนละเท่าไหร่คะ
Hong ni khuen la thao rai kha?
How much is this room per night?

A shorter market question is:

เท่าไหร่ครับ/คะ
Thao rai khrap/kha?
How much?

This is one of the first phrases many visitors use when they ask questions in Thai.

Ask “How Many?” With Ki

The word:

กี่ — ki — how many

usually comes before a classifier.

The common pattern is:

Noun + ki + classifier

Examples:

กี่คนครับ
Ki khon khrap?
How many people?

น้ำกี่ขวดคะ
Nam ki khuat kha?
How many bottles of water?

พักกี่คืนครับ
Phak ki khuen khrap?
How many nights will you stay?

มีลูกกี่คนคะ
Mi luk ki khon kha?
How many children do you have?

Common classifiers include:

คน — khon — people

ขวด — khuat — bottles

คัน — khan — vehicles

ห้อง — hong — rooms

ใบ — bai — many flat items, bags, tickets, and containers

Beginners can learn classifiers gradually through frequently used questions.

Ask “Which?” With Nai

The word:

ไหน — nai — which or where

can be used after a noun to mean “which.”

Examples:

เอาอันไหนครับ
Ao an nai khrap?
Which one would you like?

คุณชอบร้านไหนคะ
Khun chop ran nai kha?
Which shop do you like?

ไปทางไหนครับ
Pai thang nai khrap?
Which way should I go?

รถคันไหนคะ
Rot khan nai kha?
Which vehicle?

The pattern is generally:

Noun or classifier + nai

This is useful when choosing between several objects, places, or routes.

Ask About A Person’s Name

A standard polite question is:

คุณชื่ออะไรครับ/คะ
Khun chue arai khrap/kha?
What is your name?

A more natural version in a friendly conversation may omit khun:

ชื่ออะไรครับ/คะ
Chue arai khrap/kha?
What is your name?

To ask another person’s name:

เขาชื่ออะไรครับ
Khao chue arai khrap?
What is his or her name?

To answer:

ผมชื่อเดวิดครับ
Phom chue David khrap.
My name is David.

ฉันชื่อแอนค่ะ
Chan chue Ann kha.
My name is Ann.

Ask Where Someone Comes From

Use:

มาจากไหน — ma chak nai — come from where

Examples:

คุณมาจากไหนครับ
Khun ma chak nai khrap?
Where are you from?

มาจากประเทศอะไรคะ
Ma chak prathet arai kha?
Which country are you from?

Answers:

ผมมาจากสวีเดนครับ
Phom ma chak Sweden khrap.
I come from Sweden.

ฉันมาจากประเทศไทยค่ะ
Chan ma chak prathet Thai kha.
I come from Thailand.

This is a useful social pattern when you begin to ask questions in Thai during introductions.

Ask Where Someone Lives

Use:

อยู่ที่ไหน — yu thi nai — live or be located where

Examples:

คุณอยู่ที่ไหนครับ
Khun yu thi nai khrap?
Where do you live?
Where are you?

A clearer question about home is:

คุณอยู่แถวไหนคะ
Khun yu thaeo nai kha?
Which area do you live in?

คุณอยู่กรุงเทพฯ ไหมครับ
Khun yu Krung Thep mai khrap?
Do you live in Bangkok?

Be aware that asking exactly where someone lives may feel personal if you have just met.

Ask Whether Someone Can Do Something

Use the pattern:

Verb + dai mai?

The word dai means can or be able to in this structure.

Examples:

พูดภาษาไทยได้ไหมครับ
Phut phasa Thai dai mai khrap?
Can you speak Thai?

ช่วยได้ไหมคะ
Chuai dai mai kha?
Can you help?

จ่ายด้วยบัตรได้ไหมครับ
Chai duai bat dai mai khrap?
Can I pay by card?

เข้าไปได้ไหมคะ
Khao pai dai mai kha?
Can I go inside?

This pattern is especially useful when you need permission, assistance, or information about what is possible.

Ask For Permission With Dai Mai

The same pattern can politely request permission.

Examples:

นั่งตรงนี้ได้ไหมครับ
Nang trong ni dai mai khrap?
Can I sit here?

ถ่ายรูปได้ไหมคะ
Thai rup dai mai kha?
Can I take a photograph?

เปิดหน้าต่างได้ไหมครับ
Poet na tang dai mai khrap?
Can I open the window?

พาเด็กเข้าได้ไหมคะ
Pha dek khao dai mai kha?
Can children enter?

Using dai mai allows beginners to ask questions in Thai without sounding demanding.

Ask Whether Something Exists

Use:

มี…ไหม — mi…mai — is there, do you have

Examples:

มีห้องน้ำไหมครับ
Mi hong nam mai khrap?
Is there a toilet?

มีอาหารมังสวิรัติไหมคะ
Mi ahaan mangsawirat mai kha?
Do you have vegetarian food?

มีไซซ์ใหญ่ไหมครับ
Mi sai yai mai khrap?
Do you have a larger size?

มีที่นั่งสำหรับเด็กไหมคะ
Mi thi nang samrap dek mai kha?
Do you have a seat for children?

This is one of the most practical Thai question patterns for shops, hotels, restaurants, and travel.

Ask Whether Someone Wants Something

Use:

Ao…mai?

The word:

เอา — ao — take, want, choose

Examples:

เอากาแฟไหมครับ
Ao kafae mai khrap?
Would you like coffee?

เอาถุงไหมคะ
Ao thung mai kha?
Would you like a bag?

เอาอันนี้ไหมครับ
Ao an ni mai khrap?
Would you like this one?

A customer may also answer:

เอาครับ/ค่ะ
Ao khrap/kha.
Yes, I will take it.

ไม่เอาครับ/ค่ะ
Mai ao khrap/kha.
No, I do not want it.

Ask What Someone Wants

Use:

Yak dai arai? or ao arai?

Examples:

อยากได้อะไรครับ
Yak dai arai khrap?
What would you like?

เอาอะไรคะ
Ao arai kha?
What would you like?

อยากกินอะไรครับ
Yak kin arai khrap?
What do you want to eat?

อยากไปไหนคะ
Yak pai nai kha?
Where do you want to go?

These patterns combine question words with ordinary Thai sentence order.

Ask Questions In A Restaurant

Useful restaurant questions include:

อันนี้คืออะไรครับ
An ni khue arai khrap?
What is this?

เผ็ดไหมคะ
Phet mai kha?
Is it spicy?

มีหมูไหมครับ
Mi mu mai khrap?
Does it contain pork?

มีถั่วไหมคะ
Mi thua mai kha?
Does it contain nuts?

ทำไม่เผ็ดได้ไหมครับ
Tham mai phet dai mai khrap?
Can you make it not spicy?

จานนี้สำหรับกี่คนคะ
Chan ni samrap ki khon kha?
How many people is this dish for?

คิดเงินด้วยครับ/ค่ะ
Khit ngoen duai khrap/kha.
The bill, please.

Although the last phrase is technically a request rather than a question, it is useful in the same situation.

Ask Shopping Questions

Useful questions include:

อันนี้เท่าไหร่ครับ
An ni thao rai khrap?
How much is this?

มีสีอื่นไหมคะ
Mi si uen mai kha?
Do you have another colour?

มีไซซ์เล็กไหมครับ
Mi sai lek mai khrap?

ลองได้ไหมคะ
Long dai mai kha?
Can I try it?

ลดได้ไหมครับ
Lot dai mai khrap?
Can you reduce the price?

รับบัตรไหมคะ
Rap bat mai kha?
Do you accept cards?

These examples help visitors ask questions in Thai during everyday shopping.

Ask For Directions

Useful direction questions include:

ไปสถานีรถไฟฟ้ายังไงครับ
Pai sathani rot fai fa yang ngai khrap?
How do I get to the train station?

ห้องน้ำไปทางไหนคะ

Which way is the toilet?

ไกลไหมครับ
Klai mai khrap?
Is it far?

เดินไปได้ไหมคะ
Doen pai dai mai kha?
Can I walk there?

ใช้เวลากี่นาทีครับ
Chai wela ki nathi khrap?
How many minutes does it take?

ต้องเลี้ยวตรงไหนคะ
Tong liao trong nai kha?
Where do I need to turn?

Listen for pointing and gestures as well as words, because directions may include unfamiliar vocabulary.

Ask Transport Questions

Useful taxi, bus, and train questions include:

ไปที่นี่ได้ไหมครับ
Pai thi ni dai mai khrap?
Can you go here?

ค่าโดยสารเท่าไหร่คะ
Kha doisan thao rai kha?
How much is the fare?

รถออกกี่โมงครับ
Rot ok ki mong khrap?

Do I need to change vehicles?

ถึงกี่โมงครับ
Thueng ki mong khrap?
What time will it arrive?

ลงที่ไหนคะ
Long thi nai kha?
Where should I get off?

These questions can make transport easier even when your Thai vocabulary is still limited.

Ask Health And Pharmacy Questions

Simple health-related questions include:

มีร้านขายยาใกล้ๆ ไหมครับ
Mi ran khai ya klai klai mai khrap?
Is there a pharmacy nearby?

หมออยู่ที่ไหนคะ
Mo yu thi nai kha?
Where is the doctor?

ต้องกินยานี้ยังไงครับ
Tong kin ya ni yang ngai khrap?
How should I take this medicine?

กินวันละกี่ครั้งคะ
Kin wan la ki khrang kha?
How many times per day should it be taken?

มีผลข้างเคียงไหมครับ
Mi phon khang khiang mai khrap?
Are there side effects?

For important medical information, make sure you fully understand the answer. Use professional interpretation assistance when necessary.

Pronouns Can Be Omitted

Thai speakers often leave out “I,” “you,” “he,” or “she” when the meaning is clear.

Full version:

คุณไปไหนครับ
Khun pai nai khrap?
Where are you going?

Natural shorter version:

ไปไหนครับ
Pai nai khrap?
Where are you going?

Full version:

คุณชอบไหมคะ
Khun chop mai kha?
Do you like it?

Shorter version:

ชอบไหมคะ
Chop mai kha?
Do you like it?

When you first learn to ask questions in Thai, including khun may help you understand the structure. Later, you can omit it when the listener is obvious.

Use Names And Titles Instead Of “You”

Thai speakers may use a name, family term, or professional title instead of khun.

Examples:

พี่ไปไหนครับ
Phi pai nai khrap?
Where are you going?

น้องชื่ออะไรคะ
Nong chue arai kha?
What is your name?

คุณหมอว่างไหมครับ
Khun mo wang mai khrap?
Is the doctor available?

อาจารย์อยู่ที่ไหนคะ
Ajan yu thi nai kha?
Where is the teacher?

These choices reflect age, familiarity, and social relationship.

Beginners can safely begin with khun, then gradually learn other forms through listening.

Intonation Still Matters

Thai questions use question particles and question words, but intonation also affects how the sentence sounds.

A gentle tone can make a question feel friendly. A sharp or impatient tone may sound demanding, even if the words are grammatically polite.

Avoid speaking too loudly or rushing through the final polite particle.

It is better to ask questions in Thai slowly and clearly than to speak quickly with unclear tones.

Common Beginner Mistakes

Moving Every Question Word To The Beginning

Thai question words often remain where the answer would normally appear.

Correct:

คุณกินอะไร
Khun kin arai?

Forgetting The Polite Particle

A question may still be understandable, but khrap or kha often makes it more appropriate with strangers.

Confusing The Two Mai Words

ไม่ — mai means not.

ไหม — mai creates a yes-or-no question.

They have different tones and Thai spellings.

Repeating Khun Too Often

Using khun in every sentence can sound unnecessary. Thai often omits the subject.

Asking A Personal Question Too Soon

Questions about age, salary, relationships, or home location may feel personal depending on the situation.

Translating English Word For Word

Thai questions often use simpler structures than English.

Using A Demanding Tone

Correct words can still sound impolite when spoken sharply.

Avoiding these mistakes will make it easier to ask questions in Thai naturally.

A Simple Practice Method

Begin with a statement:

คุณชอบกาแฟ
Khun chop kafae.
You like coffee.

Turn it into a yes-or-no question:

คุณชอบกาแฟไหม
Khun chop kafae mai?
Do you like coffee?

Replace the object with arai:

คุณชอบอะไร
Khun chop arai?
What do you like?

Ask about another person:

ใครชอบกาแฟ
Khrai chop kafae?
Who likes coffee?

Ask for a place:

ซื้อกาแฟที่ไหน
Sue kafae thi nai?
Where can I buy coffee?

Changing one part at a time helps you understand how Thai questions are built.

Useful Question Patterns To Memorise

👉 “Readers practicing everyday questions may also explore this simple introduction to Thai sentence patterns for a clearer understanding of basic word order and structure.”

Conclusion

Beginners can ask questions in Thai using a small number of flexible patterns. Thai usually keeps normal sentence order, so you do not need to rearrange verbs and subjects as often as in English.

Add mai to the end of a statement to form many yes-or-no questions. Use arai for what, thi nai for where, khrai for who, muea rai for when, thammai for why, and yang ngai for how.

Use thao rai to ask how much, ki with a classifier to ask how many, and ki mong to ask what time. The patterns mi…mai and verb + dai mai are especially useful for asking whether something exists or is possible.

Add khrap if you are a male speaker and kha if you are a female speaker to make your questions more polite.

Remember that Thai speakers frequently omit pronouns when the listener or subject is obvious. Question words also normally remain in the position where the missing information belongs.

The best way to learn to ask questions in Thai is to practise short, reusable patterns about food, prices, directions, transport, names, time, and everyday needs. Start slowly, listen carefully to the answer, and build your vocabulary one situation at a time.
