Prefixes and Suffixes
Grammar Rule in 30 Seconds
Lao uses specific prefixes like 'ການ' (kaan) and 'ຄວາມ' (khwaam) to transform verbs and adjectives into abstract nouns.
- Use 'ການ' (kaan) before verbs to create nouns: 'ການກິນ' (eating/the act of eating).
- Use 'ຄວາມ' (khwaam) before adjectives for abstract concepts: 'ຄວາມດີ' (goodness).
- Use 'ຜູ້' (phuu) to create agent nouns: 'ຜູ້ສອນ' (teacher/instructor).
