In Isaan (Northeastern Thai / Lao dialect), “where is…?” is commonly said as:
👉 อยู่ไส (yùu sǎi) = where is…?
How to use it:
- ห้องน้ำอยู่ไส (hông-nám yùu sǎi) = Where is the bathroom?
- ตลาดอยู่ไส (tà-làat yùu sǎi) = Where is the market?
- ร้านอาหารอยู่ไส (ráan aa-hǎan yùu sǎi) = Where is the restaurant?
Notes:
- ไส (sǎi) = where (Isaan/Lao)
- This is more casual and local than standard Thai
