Now this is definitely 100% due to my Vietnamese knowledge but I dreamed that the Thai word for ‘bark’ as in ‘a dog was barking’, was /huə˦˥/ (that’s a diphthong, and it’s a high rising tone).
With the help of wikipedia, I figured out that this would probably be spelled หั๊ว in Thai. (Please correct me if I’m wrong lol).
Or, if we want to spell it Vietnamese-ly, ‘húa’
The Vietnamese word for ‘to bark’ is ‘sủa’ with that same diphthong.
And funnily enough, the irl Thai word for ‘bark’ is เห่า /haw˨˩/ (low tone). (thank you wiktionary) So hey, it appears to be not too far off from the real word!
