Nothing in terms of their definitions or way theyre used. The main difference I've read about is that 예 is used more often in speech than 네.
I read somewhere 네 is 'Yes' in yes or no question, meaning if you say 네 you're agreeing with their question.
Correct; furthermore, in a lot of major languages, Korean included, "Yes" means you agree with the question-statement. In English, this causes ambiguity, which then requires a supplementary clause to define the "yes" further, which is why most speakers use "no" in a negative question. Compare: "You don't want coffee?" English - "Yes (???)" / "No (I don't)" / "No, I do" Korean - "네 [Yes] I don't want coffee"
Slavic languages do this too, to the best of my knowledge. Some Germanic languages as well.
Just as a helpful note, this term is not widely used among Koreans. ^^ There are much more popular ways to say welcome in Korea.
Does this welcome mean "you're welcome" or "welcome (to this place)" Also do native korean speakers usually say the first in a specific way? I usually hear in comfortable dialogue they will just say something like "네~" in response to a 'thank you'
i don't understand the difference between 예and 네. I thought that 네 was more casual, like yeah instead of yes which sounds more formal
