Korean speakers may mistake them for native Korean words or connect them with wrong Chinese characters. In this article, the author applies “character-search” methodology and “sound-search” methodology for searching for the original characters of Chinese loan words which have lost connection with their graphic forms in Korean. With “character-search” methodology, this article confirms the origin of “pan-tsi (반지, which means “ring” in Korea)” is “扳指”, and with “sound-search” methodology, this article verifies the origin of Korean words “kje-ʦa (겨자, mustard)”, “∅u.tu (우두, the head)”, “sen.pi (선비, a learned man)”, and “mai (매, a quern)” are “芥子”, “為頭”, “先輩” and “磨” respectively.
