How to say “To be at” in Thai
อยู่
yùu
“to be at / stay”
“To be at” in Thai is อยู่, written yùu in the Latin alphabet.
Tone
อยู่ 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 อยู่ with that same shape.
