Which one should you use?
While ขอบคุณ is the standard form, ขอบใจ (kɔ̀ɔp-jai) is used specifically when speaking to people of lower status or younger than you, such as children or close friends.
Is there a formal and an informal way to say it?
For a casual and friendly way to say thank you, you can use Khop khun na. In formal situations, males typically use Khàawp-khun khráp and can add emphasis by using Khàawp-khun mâak.
How do you pronounce it?
The romanization is kɔ̀ɔp-kun. It has 2 syllables and the IPA transcription is /kʰɔːp̚˨˩.kʰun˧/.
When do people say it?
When saying ขอบคุณ in a formal or respectful context, it is customary to perform a wai (ไหว้). This involves pressing your palms together at chest level and bowing your head.
Did you know?
- When performing a wai while saying khop khun, the height of your hands can signal your level of respect. For a truly deep expression of gratitude, your thumbs should touch your nose.
- In very close relationships, saying ขอบคุณ too frequently can actually feel cold or distant, as it creates a formal boundary between friends.
- The word คุณ in ขอบคุณ is also the standard polite pronoun for 'you' in Thai. Using it in a thank you phrase acknowledges the other person's inherent value and kindness.
