Which word is more suitable for formal conversations when we try to say that the food or liquid that was in our stomach comes up and out of our mouth in polite way without sounding too technical ?
and which one mostly is used by doctors ( more techinal) ?
“Throw up” would probably be the right choice in the situation you’re describing. It is relatively polite but not technical.
A doctor would use the word “vomit” or if they were being more casual “throw up”.
“Puke” is more informal and has more of a disgusting tone than the others, even though it means the same thing.
