Grammar Rule in 30 Seconds
Thai politeness relies on gendered particles: 'khrap' for men and 'kha' for women at the end of every sentence.
- Men add 'khrap' (ครับ) to end sentences: 'Khop khun khrap' (Thank you).
- Women add 'kha' (ค่ะ) to end sentences: 'Khop khun kha' (Thank you).
- Use 'kho thot' (ขอโทษ) for both 'sorry' and 'excuse me'.
