How to say “To do” in Thai
ทำ
tham
“to do / make”
“To do” in Thai is ทำ, written tham in the Latin alphabet.
Tone
ทำ carries a mid tone — level, no movement. 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 “Yeah.” out loud — bored and flat, your voice at rest and going nowhere — then say ทำ with that same shape.
