ABSTRACT

Vowel system in Middle Korean was interfaced with the features [口蹙] and [口張] on the based of [舌縮] as being directly interpreted in ‘訓民正音’. Accordingly it was essentialy needed to understand the phonetic and phonological meanings of these terms correctly. Moreover the meaning of a basic term [舌縮] was important to establish the vowel system in Middle Korean. In this paper I suggested that this term had to be understood as a advanced tongue root. The tongue body was diagnally advanced and heightened when the tongue root was advanced. This property could be featuralized as [ATR] like a Proto-Siberian languages and a west african languages. The underlying vowel system of Middle Korean was composed of 4 vowels which was represented as I, U, A, ɨ. These 4 underlying vowels was surfaced as ㅣ1, ㅣ2, ㅡ, ㆍ, ㅜ, ㅗ, ㅓ, ㅏ by being supplied a default value and a floating value [ATR]. Among these ㅣ1 ,ㅡ, ㅜ, ㅓ were classified as [+ATR], while ㅣ2 ㆍ, ㅗ, ㅏ were classified as [-ATR] and so they were made up a natural class. On the basis of this vowel system, The [ATR] vowel harmony system was activated in Old Korean. After that time, ㅣ1 andㅣ2 were neutralized to ㅣ because a [ATR] contrast was disappeared at that position of this vowel system. Following this event ㅓ and ㅏ, ㆍ and ㅡ were neutralized again. I also suggested that the reason of this neutralization was a antagonistic relation of the composal features [+ATR] and [-high]. Therefore the direction of neutralization ㆍ>ㅡ was determined by this featural relation.
