네. [ne] = Yes.
아니요. [aniyo] = No.
But in Korean, when people say “네”, it is not the same as saying “Yes.” in English. The same goes for “아니요” too. This is because the Korean “네” expresses your “agreement” to what the other person said. And “아니요” expresses your “disagreement” or “denial” to what the other person said.
