In this easy-to-follow guide, we’ll walk you through must-know Thai vocabulary for family: starting with your own “parents” (พ่อแม่ – pôo mâae), your partner’s parents, and beloved “grandparents” (ปู่ย่าตายาย – bpùu yâa dtaa yaai), all the way through “siblings” (พี่น้อง -pîi nóng), “children and grandchildren” (ลูกหลาน – lûuk lǎan), and extended relatives.
Whether you’re brushing up for a family trip to Thailand or finally having that long-awaited conversation with your grandma, these words are your bridge to something deeper.
Let’s begin this journey of reconnection—one meaningful word at a time.

Thai Vocabulary For Family: Your Parents
In Thai families, the bond between parents and children runs deep.
Parents are seen not only as caregivers but as lifelong sources of wisdom and moral guidance.
It’s common in Thai culture for children—even well into adulthood—to express gratitude by helping financially or returning home to care for aging parents.
This respect for one’s elders is woven into everyday life and reflected in language.
The words for mother and father are simple yet powerful.
The word แม่ (mâae) is used for “mother,” and พ่อ (pɔ̂ɔ) is used for “father.”
These terms are among the first that Thai children learn to speak—and for heritage learners, they may be the first step toward reconnecting with family in a meaningful way.
| English | Thai | Pronunciation | Sound |
|---|---|---|---|
| Parent | พ่อแม่ | pɔ̂ɔ mɛ̂ɛ | |
| Father | พ่อ | pɔ̂ɔ | |
| Mother | แม่ | mɛ̂ɛ | |
| Father (formal) | บิดา | bì daa | |

Thai Vocabulary For Family: Your Partner’s Parents
When you build a life with a Thai partner, your relationship naturally extends to their family.
In Thai culture, familial ties are honored and deeply valued.
Referring to your partner’s parents with proper terms is not only respectful but helps you become truly part of the family.
For a polite and warm address, Thai people commonly use คุณพ่อ (khun pɔ̂ɔ) for “father” and คุณแม่ (khun mâae) for “mother.”
These are safe and respectful terms you can use with any parent figure.
If you want to specify whose parents you’re referring to, there are distinct words.
The wife’s father is พ่อภรรยา (phâaw pan-ra-yaa) and her mother is แม่ภรรยา (mâae pan-ra-yaa).
On the husband’s side, the father is พ่อสามี (phâaw sǎa-mii) and the mother is แม่สามี (mâae sǎa-mii).
These phrases literally translate to “father of wife” or “mother of husband,” making it easy to remember who is who.
| English | Thai | Pronunciation | Sound |
|---|---|---|---|
| Husband | สามี | sǎa mii | |
| Wife | ภรรยา | pan ra yaa | |
| Father of partner (Polite address) | คุณพ่อ | khun pɔ̂ɔ | |
| Mother of partner (Polite address) | คุณแม่ | khun mɛ̂ɛ | |
| Father-in-law/father of wife (formal) | พ่อภรรยา | pɔ̂ɔ pan ra yaa | |
| Mother-in-law/mother of wife (formal) | แม่ภรรยา | mɛ̂ɛ pan ra yaa | |
| Father-in-law/father of husband (formal) | พ่อสามี | pɔ̂ɔ sǎa mii | |
| Mother-in-law/mother of husband (formal) | แม่สามี | mɛ̂ɛ sǎa mii | |
| Father-in-law/father of wife (casual) | พ่อตา | pɔ̂ɔ dtaa | |
| Mother-in-law/mother of wife (casual) | แม่ยาย | mɛ̂ɛ yaai | |
| Father-in-law/father of husband (casual) | พ่อปู่ | pɔ̂ɔ bpùu | |
| Mother-in-law/mother of husband (casual) | แม่ย่า | mɛ̂ɛ yâa |
Did you notice that there are some casual or affectionate ways to refer to your father-in-law and mother-in-law?
You might also hear terms like พ่อปู่ (phôo bpùu) for father-in-law and แม่ยาย (mâae yaai) for mother-in-law.
These compound words mix “parent” and “grandparent,” reflecting both respect and emotional closeness.
Thai Vocabulary For Family: Grandparents
In Thailand, grandparents are treasured figures who often play an active role in raising grandchildren and preserving Thai cultural traditions.
Thai makes a clear distinction between maternal and paternal grandparents, offering specific terms that reflect the family lineage.
On the father’s side, grandfather is called ปู่ (bpùu) and grandmother is ย่า (yâa).
On the mother’s side, grandfather is ตา (dtaa) and grandmother is ยาย (yaai).
Collectively, the term “grandparents” is ปู่ย่าตายาย (bpùu yâa dtaa yaai) in Thai.
These terms not only indicate the side of the family but also carry a deep sense of affection and respect.
When you use them, you’re honoring not just a person but an entire legacy.
| English | Thai | Pronunciation | Sound |
|---|---|---|---|
| 1. Grandparents | ปู่ย่าตายาย | bpùu yâa dtaa yaai | |
| 2. Grandfather (paternal) | ปู่ | bpùu | |

| 9. Great-grandmother (maternal) | ยายทวด | yaai tûat |
Thai Vocabulary For Family: Siblings
Thai places a strong emphasis on age hierarchy, which is clearly reflected in the vocabulary used for siblings.
Unlike English, which simply distinguishes between brothers and sisters, Thai differentiates between older and younger siblings regardless of gender.
To indicate age, the word พี่ (phîi) is used for an older sibling, while น้อง (nóng) refers to a younger sibling.
To further specify male or female sibling, gender is added: พี่ชาย (phîi chaai) means older brother, พี่สาว (phîi săao) means older sister, น้องชาย (nóng chaai) means younger brother, and น้องสาว (nóng săao) means younger sister.
This age-based system reflects Thai values of deference to elders and creates a sense of order and respect within the family structure.
For those reconnecting with long-lost siblings or cousins, these terms help you speak with authenticity and warmth.
| English | Thai | Pronunciation | Sound |
|---|---|---|---|
| 10. Siblings | พี่น้อง | pîi nɔ́ɔng | |
| 11. Older brother | พี่ชาย | pîi chaai | |
| 12. Younger brother | น้องชาย | nɔ́ɔng chaai | |
| 13. Older sister | พี่สาว | pîi sǎao | |
| 14. Younger sister | น้องสาว | nɔ́ɔng sǎao | |
| 15. Cousin | ลูกพี่ลูกน้อง | lûuk pîi lûuk nɔ́ɔng |
Thai Vocabulary For Family: Children
In Thai, children are often seen as blessings who carry the hopes of the family into the future.
The language used to refer to them is both affectionate and practical, allowing you to express love and pride easily.
To refer to children, use the word ลูก “child” plus ชาย “male” or สาว “female”— ลูกชาย (lûuk chaai) for “son”, ลูกสาว (lûuk săao) for “daughter.”
These are commonly used when speaking to or about one’s children.
To refer to grandchildren, nieces, or nephews, the word หลาน (lǎan) is used as a prefix.
For example, หลานชาย (lǎan chaai) refers to a grandson or nephew, and หลานสาว (lǎan săao) refers to a granddaughter or niece.
This shared root word for younger relatives simplifies the vocabulary and reflects the collective closeness of the extended family.
| English | Thai | Pronunciation | Sound |
|---|---|---|---|
| 16. Child | ลูก | lûuk | |
| 17. Grandchild | หลาน | lǎan | |
| 18. Great-grandchild | เหลน | lěen | |
| 19. Son | ลูกชาย | lûuk chaai | |

How To Address Your Thai Family Member: 4 Scenarios
Knowing what to call your family members is about more than just vocabulary—it’s a way to show care, closeness, and respect for your roots.
While earlier sections gave you the core Thai vocabulary for family, this part helps you actually use them in real-life conversations.
In Thai, how you address someone directly can differ from how you refer to them in conversation with others.
Below are four real-life scenarios to guide you—whether you’re meeting your grandmother for the first time in years, or finally texting your cousin in Thai. Let’s go!
Scenario 1: Use น้อง (nóng) for younger Siblings, cousins, nieces, or nephews
In Thai culture, age hierarchy is everything.
Anyone younger than you—even by just a few months—is addressed with น้อง (nóng).
It’s a term of endearment and acknowledgment of seniority.
When calling your younger sibilings, cousin or nephew, it’s perfectly fine to just say น้อง (nóng) or call their Thai nicknames.
Thai people often go by nicknames, which are usually short, playful, and easy to remember.
If you forget the full name, calling someone just by their nickname is still affectionate and accepted.
| Formula | Example | Pronunciation | Translation | Sound |
|---|---|---|---|---|
| น้อง (nóng) “younger family member” | น้อง | nóng | “Little one” | |
| One or two-syllable Thai nickname | เอ๋ | ae | “Ae” |
Scenario 2: Use พี่ (phîi) for older siblings or cousins
In Thai, the prefix พี่ (phîi) is used for older siblings and anyone just a bit older than you—even coworkers or friends.
In a family setting, this shows that you recognize and respect their seniority.
It’s polite and affectionate, and you can use it with both males and females.
What’s great is that you don’t always need to specify gender (e.g. พี่ชาย or พี่สาว).
Just using พี่ plus their nickname is warm, respectful, and very natural.
| Formula | Example | Pronunciation | Translation | Sound |
|---|---|---|---|---|
| พี่ (phîi) + nickname | พี่ + แอน | phîi aen | “Older brother aen” |
Scenario 3: Use ลุง (lung)/ น้า (náa)/ ป้า (bpâa)/ อา (aa) + “name” for your aunts and uncles
In Thai, aunts and uncles are categorized by age relative to your parents and which side of the family they’re on. To recap:
- อา (aa): Used for younger siblings of your father.
- น้า (náa): Used for younger siblings of your mother.
- ป้า (bpâa): Used for any older sister of either parent.
- ลุง (lung): Used for any older brother of either parent.
When speaking directly to them?
You only need to use the appropriate title plus their nickname (yes it’s appropriate to call them by their nickname if is being used by the whole family).
If you’re in a small family or there’s no confusion, saying just the title is enough.
But in larger gatherings, adding their name helps avoid mix-ups and makes the interaction personal.
| Formula | Example | Pronunciation | Translation | Sound |
|---|---|---|---|---|
| ลุง (lung) + name | ลุงทิม | lung tim | “Older uncle Tim” | |
| น้า (náa) + name | น้าแอน | náa aen | “Younger aunt Aen” |
Scenario 4: Use คุณ (khun) + grandparent title to show reverence and care
When speaking to or about your grandparents, adding the respectful prefix คุณ (khun) before their family role—like คุณยาย (khun yaai) for grandmother or คุณปู่ (khun bpùu) for grandfather—is both traditional and deeply respectful.
It’s a beautiful way to express both closeness and formality, especially if you’re visiting them after a long time or speaking to them in Thai for the first time.
| Formula | Example | Pronunciation | Translation | Sound |
|---|---|---|---|---|
| คุณ (khun) + ยาย (yaai) “Grandmother (maternal)” | คุณยาย | khun yaai | “Granny/ Nana” | |
| คุณ (khun) + ปู่ (bpùu) “Grandfather (paternal)” | คุณปู่ | khun bpùu | “Grandpa, Poppy” |
How Do You Say Family in Thai Language?
The Thai word for “family” is ครอบครัว (khrôop-khrua), and it holds more meaning than just a group of relatives—it reflects unity, shared responsibility, and emotional closeness.
For roots seekers looking to connect with their Thai lineage, understanding this word is a powerful first step.
ครอบ (khrôop) means “to enclose,” and ครัว (khrua) means “kitchen,” symbolizing the warmth and togetherness of family relationships in Thai.
Through Ling’s immersive and culturally-rooted language lessons, you can move beyond vocabulary and start speaking with the people who’ve shaped your identity—especially those waiting to hear from you, like grandparents and extended kin.
Frequently Asked Questions About Thai Vocabulary For Family
What Do Thai People Call Their Mom?
In Thai, the word for “mom” is แม่ (mâae)—a short, soft word that carries so much love, care, and respect. Whether you’re calling your mother directly or talking about her to someone else, the tone and usage shift slightly, showing how Thai reflects deep cultural nuances in family roles.
What Does Khun Mean In Thai?
Khun (คุณ) is a respectful title used before someone’s name in Thai, similar to “Mr.” or “Ms.” in English—but it’s also much more personal. It’s how you address elders, parents, and relatives in a way that honors them, making it an essential word for anyone hoping to speak to their grandparents or extended family.
What Does Phua Mean In Thai?
In Thai, ผัว (phǔa) is the informal word for “husband,” typically used in everyday speech—but it’s worth noting that it’s considered quite casual and, in some settings, even impolite. Thai has more refined alternatives like สามี (sǎa-mii), which is used in formal or polite contexts. If you’re reconnecting with family or speaking with elders, especially in Thai households that value manners and hierarchy, using the right term matters.
