How to Say Yes in Thai (Formal vs Casual)

Two ways to say yes in Thai

Thai changes with who you are talking to. With a stranger, a shop owner or someone older, the safe, polite yes is chai (ใช่). Among friends you will hear a relaxed err (เออ), the casual yes that sounds warm and familiar.

Getting this right matters in Phuket. Use chai at a hotel desk, a market stall or with an elder and you sound respectful. Drop into err with friends your own age and you sound natural instead of stiff.

A quick tip: when in doubt, stay polite with chai. Thai people rarely mind a visitor being a little too formal, but the casual err with the wrong person can feel too familiar. This short Thai reel shows both side by side so you can hear the difference and copy the tone.
