The wai: Thailand's greeting

The wai is the graceful Thai greeting: press your palms together like a prayer and raise them toward your chin or nose, with a small bow of the head. It means hello, thank you, sorry, and goodbye. There is a social logic to it: the younger or lower-status person wais first and higher; monks receive the highest wai and never return one to laypeople. As a visitor you do not need to master every level - simply return a wai when someone offers you one, with a smile. You are not expected to wai first, and you should not wai children or people serving you (a smile and nod is right there). Do not wai with something in your hands, and keep it gentle - this is not a performance. When in doubt, a warm smile and slight bow of the head is always acceptable and appreciated.

Highlights

• Palms together at chin level with a slight bow
• Return a wai when offered - that is the main rule for visitors
• Higher hands = more respect (monks receive the highest)
• Don't wai children or service staff first; a smile is enough

Local tips

• A smile plus a small head bow works everywhere if you are unsure
• Never wai while holding bags or a drink - put them down or just smile
