How to say “Sour” in Thai
เปรี้ยว
prîeaw
“sour”
“Sour” in Thai is เปรี้ยว, written prîeaw in the Latin alphabet.
Tone
เปรี้ยว carries a falling tone — starts high, drops hard. Thai uses tone to tell words apart, so the pitch is part of the word, not an accent you can drop.
The shortest way in is an English intonation you already use. Say “NO!” out loud — snapped at a dog going for the food on the table — then say เปรี้ยว with that same shape.
