The word Cheju or Jeju refers to Jeju Island, which is the largest island in South Korea. The etymology of the word Cheju can be traced back to the island's original name in the Jeju dialect, which is Tammora. Over time, the pronunciation and spelling evolved, and it became Tamna. During the Goryeo Dynasty, the name was changed to Tangna, based on the Chinese characters used to write it. Later, during the Joseon Dynasty, it was changed again to Jejuyo or Quelpart as it was known by Western explorers. Eventually, the name was shortened to Jeju.
