Grammar Rule in 30 Seconds

In Thai, you make commands polite by adding 'khrap' (male) or 'kha' (female) at the end of your sentence.

  • Use 'khrap' if you are male: 'Kin khao khrap' (Please eat).
  • Use 'kha' if you are female: 'Kin khao kha' (Please eat).
  • Add 'noi' to soften the command: 'Kin khao noi kha' (Please eat a little).
Verb + Object + (noi) + Particle (khrap/kha)

Overview

Alguma vez sentiu que foi rude ao pedir um favor em tailandês? A cultura tailandesa valoriza imenso a cortesia. Se simplesmente gritar come! ou vai!, parece que está a dar ordens de forma grosseira.
Para evitar isso, usamos partículas de cortesia. Adicionar na ou khrap/kha transforma uma ordem numa sugestão amigável. É como adicionar um por favor que faz com que as pessoas queiram ajudar.

Meanings

Polite imperatives are used to soften commands or requests, making them sound like invitations or polite suggestions rather than bossy orders.
