Hanja is the Korean name for Chinese characters (hànzì). More specifically, it refers to those Chinese characters borrowed from Chinese and incorporated into the Korean language with Korean pronunciation. Hanja-mal or hanja-eo refers to words that can be written with hanja, and hanmun (, ) refers to Classical Chinese writing, although "hanja" is sometimes used loosely to encompass these other concepts. Because hanja never underwent major reform, they are almost entirely identical to traditional Chinese and kyujitai characters. Only a small number of hanja characters are modified or unique to Korean. By contrast, many of the Chinese characters currently in use in Japan and Mainland China have been simplified, and contain fewer strokes than the corresponding hanja characters.
