ㄷ구개음화 발생의 역사적 전개 과정

Cause and Process of Palatalization of “ㄷ”

&nbsp;&nbsp;This study examined the cause and process of the palatalization of “ㄷ” by categorizing the phoneme phenomenon. As a result, palatalization of “ㄷ” was categorized into alveolar affrication, palatalized sound, change of the principle member of “ㅈ”(uvular), and palatalization. Each category&quot;s historical process was explained. The following are the results of this study:<BR>&nbsp;&nbsp;1. The first step of the palatalization of “ㄷ” begins with alveolar affrication. The “ㄷ” sound, which was an alveolar in the 15th century, became the “ㅈ” sound through the process of alveolar affrication.<BR>&nbsp;&nbsp;2. The second step of the palatalization of “ㄷ” is the generation of palatalized sound. The vowel “ㅣ”, which was a neutral sound in the 15th century, became a palatal and consonants such as “ㄱ, ㄴ, ㄹ, ㅅ, ㅈ, ㅉ, ㅊ, ㅎ” caused palatalized sounds with the strong influence of “ㅣ”.<BR>&nbsp;&nbsp;3. The third step of the palatalization of “ㄷ” is the change of the principle member (alveolar affrication) of “ㅈ”. The alveolar affricate [ts], which was the principle member (phoneme) of “ㅈ” since the 15th century, was replaced by the palatalized sound [t∫] and changed the phoneme of “ㅈ” to a palatal. “/ts/” lost its status as a phoneme because a plosive, affricate, and fricative filled the place of the alveolar sound and transformed itself to a palatal to create distinction.<BR>&nbsp;&nbsp;4. The palatalization of “ㄷ” is considered a phenomenon that emerged after “ㅈ” changed its principle member. Therefore, existing studies which state that “ㄷ” was replaced with “ㅈ” at the time of palatalization do not consider this phenomenon palatalization but alveolar palatalization.
