How to say “Big” in Thai
ใหญ่
yài
“big”
“Big” in Thai is ใหญ่, written yài in the Latin alphabet.
Tone
ใหญ่ carries a low tone — below your resting pitch, and it stays there. 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 “Don’t.” out loud — quiet and stern, the warning you give without raising your voice — then say ใหญ่ with that same shape.
