How to say “Foot” in Thai
เท้า
tháo
“foot / feet”
“Foot” in Thai is เท้า, written tháo in the Latin alphabet.
Tone
เท้า carries a high tone — high and strained, still pushing up at the end. 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 “Really?!” out loud — disbelieving and tight, pushed up until it almost squeaks — then say เท้า with that same shape.
