Grammar Rule in 30 Seconds

Use the suffix '-un' to give polite commands or requests to people you respect or don't know well.

  • Add '-un' to the verb root for formal requests: 'Kha' (eat) becomes 'Khan' (please eat).
  • Use 'korun' for 'do' when speaking to elders or strangers.
  • Always pair with 'apni' (formal you) to maintain consistent politeness.
Verb Root + un = Formal Command (e.g., 📖 + un = Porun)
