Have you ever wished you could say more than just “hello” or “thank you” when talking to your Thai grandparents?
Maybe you’ve heard them gently say something in Thai before bedtime and wondered what it meant—or wished you could reply in a way that truly honored your shared heritage.
Learning to say good night in Thai might seem like a small step, but for many second-generation learners or those rediscovering their cultural identity, it’s a deeply meaningful one.
For example, ฝันดี (făn dee) is a gentle way to say “sweet dreams” to someone you’re close with, like a sibling or child, while ราตรีสวัสดิ์ (raa-dtree sà-wàt) is an extremely formal and almost literary “have a blessed evening” that can be a sweet, humorous gesture to slip it into conversation to crack a smile on your grandparents’ faces.
But before we dive into them, here’s a quick tip: Thai is a polite language.
You’ll often hear people end their sentences with ครับ (khráp) if they’re male or ค่ะ (khâ) if they’re female.
These are politeness particles, and using them—especially with elders—shows respect and warmth.
However, in casual settings with close friends or family, you can skip them.
Just be mindful of when and where to use these particles, as they can make a big difference in how your greeting is received.
Now, let’s explore how to say good night in Thai in a way that helps you connect more deeply with your family and heritage.

1. สวัสดี (Sà-Wàt-Dee) – A Classic Farewell That Works Anytime
Though most learners first encounter สวัสดี (sà-wàt-dee) สวัสดี as hello in Thai.
it’s also commonly used to say goodbye in Thai, even at night.
Its versatility and politeness make it a staple of Thai conversation—appropriate for almost any age or social setting.
When you’re leaving your grandparents’ house after dinner or saying goodbye to a family member before bed, a warm สวัสดี (sà-wàt-dee) followed by the correct polite particle in Thai (ครับ khráp or ค่ะ khâ) is a respectful way to part ways.
In fact, many Thais prefer this simple farewell over more poetic phrases, especially in everyday life.
Fun fact: The word สวัสดี (sà-wàt-dee) was introduced in the 1930s during a campaign to modernize the Thai language.
It’s derived from the Sanskrit word svasti, meaning well-being or blessings.
So, when you say สวัสดี (sà-wàt-dee) to an elder, you’re actually wishing them good health and peace—a beautiful sentiment to end the day with.
2. ฝันดี (Făn Dee) – A Warm “Sweet Dreams” For Loved Ones
ฝันดี (făn dee) ฝันดี means “dream well” or “sweet dreams,” and it’s typically used in warm, close relationships—think siblings, children, or a romantic partner.
You’ll hear it exchanged between people who are emotionally close, often before bed or in a goodnight text message.
However, just like in English, it can sound a bit off if used with someone significantly older, such as a grandparent.
Saying “sweet dreams, Grandma” might come across as overly casual or childlike.
If you’re unsure, it’s best to stick with สวัสดี (sà-wàt-dee) or other more respectful farewells.
Thai culture places great importance on kreng jai—a sense of respectful consideration for others.
This means being mindful of how you speak, especially to elders.
Phrases like ฝันดี (sà-wàt-dee), while sweet, are best saved for those you speak to on more familiar terms.
3. ราตรีสวัสดิ์ (Raa-Dtree Sà-Wàt) – A Formal And Poetic Good Night
ราตรีสวัสดิ์ (raa-dtree sà-wàt) ราตรีสวัสดิ์ is the closest direct translation of “good night” in Thai and is a beautifully formal way to end the evening.
It’s made up of the Sanskrit-rooted ราตรี (raa-dtree), meaning “night,” and สวัสดิ์ (sà-wàt), meaning “blessing” or “well-being.”
Together, it’s essentially saying, “Have a blessed night.”
Historically, this phrase was used in royal or highly ceremonial contexts, which is why you’re unlikely to hear it around the dinner table.
Most native speakers don’t say this in daily life, even in polite situations.
That said, if you want to add a bit of charm or comedic effect—maybe to get a chuckle from your Thai auntie or surprise your grandparents—go ahead and give it a try!
It shows curiosity, effort, and a warm-hearted approach to connecting with your roots through language.
Bonus: อรุณสวัสดิ์” (à-run sà-wàt), on the other hand, means “Good Morning.”
Is the counterpart to ราตรีสวัสดิ์ (raa-dtree sà-wàt) and is used in highly formal or ceremonial contexts, such as royal or Buddhist settings.
“อรุณ” (à-run) means “dawn,” while “สวัสดิ์” (sà-wàt) comes from the Sanskrit word for “well-being.”
4. กู๊ดไนท์ (Gûut-Nái) – A Casual English Loanword
Borrowed from English, กู๊ดไนท์ (gûut-nái), meaning “Good night,” is widely used among Thai youth, especially in texting and social media. It’s friendly, trendy, and feels modern.
You can also hear variations like ไนท์ๆ (nái nái) “nighty night,” which adds a bit more affection or playfulness—often used with children or a romantic partner.
If you’re messaging cousins or speaking to younger relatives, using กู๊ดไนท์ (gûut-nái) can help you sound relatable and connected to contemporary Thai culture.
But for older generations—especially grandparents—it’s better to use more traditional expressions.

Quick Tips: How To Know Which Good Night Expression To Use And When
- Consider who you’re speaking to
If you’re talking to a grandparent or older relative, go for something polite and respectful like สวัสดีครับ (sawasdee kráp) or สวัสดีค่ะ (sawasdee kâ). Save playful options like ไนไน (nai nai) or ฝันดี (fan dee) for younger cousins, siblings, or close peers. It’s all about matching tone with the relationship.
2. Play it safe with “สวัสดีครับ/ค่ะ” (sawasdee kráp/kâ)
Unsure what’s appropriate? You can always use สวัสดี (sawasdee) as a safe and respectful “hello/goodbye”—including at night. It may not literally mean “good night,” but it’s polite, warm, and universally accepted by Thai elders.
3. Send a sticker or emoji if texting
Thai people love sending cute LINE stickers or emojis as a way to say good night. Try pairing your greeting with a heart or a sleeping face on WhatsApp or Instagram—it adds a layer of affection and charm your grandparents will appreciate.
4. Mirror what they say back to you
If a relative greets you first with ฝันดี (fan dee) or สวัสดี (sawasdee), simply respond with the same phrase. This makes your response naturally appropriate, and it helps you learn from how your own family uses Thai in real life.
