Mixed script or Hanja-honyong
The practice of mixing hangul into hanja began as early as the introduction of hangul.  Even King Sejong's promulgation proclamation was written in literary Chinese and idu passages to explain the alphabet and mixed passages that help 'ease' the reader into the use of the alphabet.  The first novel written in hangul, Yongbieocheonga (용비어천가; 龍飛御天歌), Songs of the Dragons Flying to Heaven, is actually mostly written in what would now be considered mixed-script writing.  Another major literary work touted as a masterpiece of hangul-based literature, the 1590 translation of The Analects of Confucius (논어; 論語) by Yi Yulgok (이율곡; 李栗谷) is also written entirely in hanja-honyong.
Many Koreans today attribute hanja-honyong to the Japanese occupation of Korea. This is in part due to the visual similarity of Chinese characters interspersed with alphabetic text of Japanese-language texts to Korean-language texts in mixed script, and the numerous assimilation and suppression schemes of the occupational government carried out against the Korean people, language and culture.  In fact, hanja-honyong was commonplace amongst the royalty, yangban (양반; 兩班) and jung-in classes for personal records and informal letters shortly after the introduction of the alphabet, and replaced the routine use of idu by the jung-in.  The heyday of hanja-honyong arrived with the Gap-o reforms (갑오; 甲午) passed in 1894 – 1896 after the Donghak Peasant Rebellion (동학농민혁명; 東學農民革命).  The reforms ended the client status of Korea to the Qing dynasty emperors, elevating King Gojong to Emperor Gwangmu (고종 광무제; 高宗 光武帝), ended the supremacy of literary Chinese and idu script, ended the gwageo imperial examinations.  In place of literary Chinese, the Korean language written in the 'national letters' (국문; 國文)—now understood as an alternate name for hangul but at the time referred to hanja-honyong—was now the language of governance.
