Question Particle 'Bo'
Grammar Rule in 30 Seconds
Turn any statement into a yes/no question simply by adding 'bo' at the end of the sentence.
- Place 'bo' at the very end of a statement to ask a yes/no question: 'ເຈົ້າກິນເຂົ້າບໍ່?' (Do you eat rice?)
- The tone remains neutral; 'bo' acts as the question mark in spoken Lao.
- You can combine it with other particles like 'ແລ້ວ' (already) to ask 'Have you eaten yet?'
