Grammar Rule in 30 Seconds

Thai instructional verbs are simple: just use the base verb, often softened with particles like 'na' or 'si' to sound polite.

  • Use the base verb for direct commands: 'Kin!' (Eat!)
  • Add 'hai' to indicate the beneficiary: 'Hai kin' (Let [someone] eat).
  • Softening particles like 'na' make commands sound like friendly suggestions.
Verb + (Object) + (Particle: na/si/hai)

Meanings

Instructional verbs are used to give orders, make requests, or provide directions. In Thai, these are often context-dependent and rely heavily on politeness particles.

1

Direct Command

A firm instruction to perform an action.

“Pai! (Go!)”

“Nang! (Sit!)”

2

Polite Suggestion

An instruction softened to sound like a request.
