In Thai, you rarely call someone by their family name or given name alone, unless they are younger than you. Instead, you put an honorific word (prefix) in front of the name, based on their age, relationship, or social role.
People in Thailand call each others like their own family members.
Thailand is a family-oriented society where community ties run deep and respect for elders is woven into daily life. Seniority—both in age and experience—plays a big part in shaping how people interact. One way this shows up clearly is in how Thais address each other.
In many Western cultures, calling someone by their first name is perfectly normal—even with new acquaintances. In Thai, you rarely call someone by their family name or given name alone, unless they are younger than you. Instead, you put an honorific word (prefix) in front of the name, based on their age, relationship, or social role. Think of it like saying “Auntie May” or “Brother Tom” in English—but it’s used all the time in daily Thai speech, and without it may sound as if you’re talking down to the person.
From a young age, children are taught that language is not just a tool for communication, but also a way to show respect. Within the family, they learn to call older siblings, parents, and relatives with specific titles that reflect both age and relationship. The honorifics are practised daily until they become second nature, shaping the child’s sense of respect and humility.
As children grow, this pattern of respectful address naturally extends beyond the family. In schools, students refer to teachers with a term that conveys both knowledge and authority. In the workplace, colleagues and supervisors are addressed according to their seniority, not just their job title. Even in casual, everyday situations, the same principle applies. Meeting a new neighbor, buying fruit at a market stall, or greeting a taxi driver—Thais instinctively reach for respectful terms. It reflects the cultural mindset that everyone is connected and should be treated as if they were part of one’s extended family.
That is why you’ll often hear people call a friendly shop owner, a taxi driver, or an elderly woman with a respectful prefix. These words don’t necessarily indicate blood relations, but they signal warmth, respect, and inclusion. The use of such honorifics softens interactions, reduces social distance, and makes even brief encounters feel more personal.
Let’s get into samples of common Thai honorifics.
1. พี่ (P’) – Older sibling / elder peer
- Used for: someone older than you (but not too much older, usually within a generation).
- Example:
- พี่แอน (P’ Ann) = Older sister Ann
- พี่บอล (P’ Ball) = Older brother Ball
- You’ll hear this constantly between friends, colleagues, or even customers and staff.
2. น้อง (Nong) – Younger sibling / junior
- Used for: someone younger than you.
- Example:
- น้องกาย (Nong Guy) = Younger Guy
- It’s affectionate and polite. Even adults call much younger colleagues “Nong.”
- In real life, people usually drop Nong and call only name of younger one.
3. คุณ (Khun) – Formal, polite title
- Similar to “Mr./Ms.”
- Used in polite or professional situations, or if you’re not sure of someone’s age.
- Example:
- คุณสมชาย (Khun Somchai) = Mr. Somchai
- คุณแหม่ม (Khun Maem) = Ms. Maem
- Safe choice for business, customer service, or formal introductions.
4. ลุง (Loong), ป้า (Pa), น้า (Na), อา (Aa) – Uncles & Aunts
- For people roughly your parents’ age.
- Which one you use depends on whether they’re older or younger than your parents and sometimes their side of the family, but in practice, many Thais just use Loong (uncle) for older men and Pa (aunt) for older women.
- Example:
- ลุงชัย (Loong Chai) = Uncle Chai
- ป้าแป๋ว (Pa Paew) = Auntie Paew
5. Other specific titles
- ครู (Khruu) = Teacher
- อาจารย์ (Ajarn) = Professor/Teacher (higher education or honorific)
- หมอ (Mor) = Doctor
- These are often combined with names:
- ครูจอย (Khruu Joy) = Teacher Joy
- หมอเก่ง (Mor Keng) = Doctor Keng
Example in conversation:
- English: “Ann, are you hungry?”
- Thai (polite): พี่แอน หิวไหมคะ/ครับ (P’ Ann, hiu mai kha/khrap?)
Please note that these honorifics are usually used when addressing people who are older or hold a social position deserving of respect. Among friends of the same age, or when speaking to someone younger, it is more common to simply use their name without any title.
For women, however, honorifics can sometimes be a sensitive matter. Being addressed with terms that imply advanced age—such as “Pa” (auntie)—can feel unpleasant or even offensive if the woman is not actually that old. To avoid this, a good tip is to use “Khun”, a neutral and polite honorific that works in nearly any situation. Another alternative often used is “Na”, which carries a softer, less age-specific meaning and can be applied to both men and women without risk of offense.
This tradition of respectful address goes beyond simple politeness—it is part of what keeps Thai society harmonious. It encourages individuals to stay mindful of their place within the social fabric and to recognize the dignity of others. By addressing people not just by name, but with a respectful title, Thais create a culture where even casual encounters are infused with warmth, consideration, and connection.
