Grammar Rule in 30 Seconds
Use 'thi' (ທີ່) to link a noun to a description, acting like 'that', 'which', or 'who' in English.
- Place 'thi' directly after the noun you are describing: 'khon thi...' (the person who...)
- Use 'thi' to introduce a verb phrase that modifies the noun: 'nangsue thi pen...' (the book that is...)
- Do not use 'thi' for simple adjectives that don't require a verb; use 'lae' or direct placement.
