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'.
Phrase + (ครับ/ค่ะ) = Polite Thai
