Have you wondered why Thai people almost always end their sentences with “krub” for guys and “ka” for girls? What do “krub” and “ka” mean in Thai? This blog will explore when you should use “krub”, “ka” and other ending particles.
What is ‘krub’ and ‘ka’ in Thai?
- ‘krub’ / ครับ which is also spelt as ‘kup’, ‘krap’ is a polite ending particle for males. This is used for both questions and normal sentences.
- ‘ka’ which is also spelt as ‘kha’ is a polite ending particle for females. For normal sentences, it has a falling tone (written khâ /ค่ะ) and for questions, it has a high tone (written khá / คะ)
Do note that because of the difference in tone, ‘ka’ used in a question is written differently from ‘ka’ used in a statement. This is differentiated by the falling tone mark for low consonants.

How to use ‘krub’ / ‘ka’ in Thai Language?
The exact meaning of “krub” and “ka” cannot be translated in English. It is simply an ending particle used in 90% of your spoken Thai sentences to make them more polite. For example, if you need to apologise, you should always say “khor thoot ka/krub” (khor thoot = sorry). You will come across as rude if you simply say “khor thoot”. Similarly, it is highly recommended to use “khop khun ka/krub” when thanking someone instead of “khop khun”. A general rule of thumb is – it does not hurt to be more polite, especially if you are a foreigner in Thailand and are unfamiliar with the Thai language.
When I was in Thailand with only a beginner Thai foundation, I took my cue from how often the other Thai party is saying “ka/krub”. After about a week of speaking Thai daily, using “ka” became second nature to me 😉
In everyday speech, you can also use “ka/krub” as a substitute for “yes”. For example:
- [In a conversation between two females; please replace “ka” with “krub” for males]
- Female A: I can use this, right? // Chan chai nii, dai mai ká? // ฉันใช้นี่ได้ไหมคะ ?
- Female B: Yes // khâ //ค่ะ
Hence, always be careful when you are translating Thai to English. Make sure you get the full context and understand the meaning to be conveyed.
Other ending particles in Thai Language
Other than “na”, I strongly advise not to use the other ending particles if you are unsure. Always check with a Thai native or someone who knows the Thai language well enough before using new terms to avoid offending someone unwittingly.

|Very commonly used to soften your sentence and make it sound more friendly. “na” can be used for both formal and informal context.

You can also say “chan ruk khun na” which is “I love you na” in Thai to sound more endearing.|
