현대 국어의 이른바 ‘ㅅ/ㄷ’ 불규칙 용언(어간)의 이형태 재고 -이형태 ‘-ㅅ/∅’, ‘-ㄷ/ㄹ’를 ‘-ㅅ/으’, ‘-ㄷ/르’로-

Abstract

This paper discussed the following problems; why the stem allomorph ‘-∅’ of ‘s(ㅅ)’ irregular predicator is combined with ‘euni(으니)’, unlike the case of a regular stem ending in a vowel. Also in the case of a regular stem ending in ‘l(ㄹ)’, ‘l(ㄹ)’ is deleted when combined with ‘euni(으니)’ but why the stem allomorph ‘-l(ㄹ)’ of ‘d(ㄷ)’ irregular predicator is combined with ‘euni(으니)’ without being deleted. To solve these problems, this paper suggested a method which can systematically adjust the obscure morph of the stem through a synchronically reasonable and consistent description on the combination of the existent morph of the stem and the ending such as the stem allomorph ‘-u(우)’ of ‘p(ㅂ)’ irregular predicator, by excluding the diachronic information related to the generation of the allomorph ‘-∅’ of ‘s(ㅅ)’ irregular predicator, or the allomorph ‘-l(ㄹ)’ of ‘d(ㄷ)’ irregular predicator. And the paper examined that the stem allomorph ‘-∅, -l(ㄹ)’ of ‘s(ㅅ), d(ㄷ)’ irregular predicator stem should be changed to ‘-eu(으), -reu(르)’. This is the because the stem final ‘b(ㅂ)’ of ‘b(ㅂ)’ irregualr predicator is changed to ‘-βu(ᄫᅮ)’ when combined with ‘eu(으)’, wherein ‘β(ㅸ)’ is deleted. The form ‘-βeu(ᄫᅳ)’ is made when ‘b(ㅂ)’ combines with ‘eu(으)’, wherein ‘β(ㅸ)’ influences ‘eu(으)’ and changes it into ‘u(우)’. As a result, a reconstruction occurred on the stem morph, and therefore ‘-u(우)’ is the stem allomorph of the ‘b(ㅂ)’ irregular predicator. The stem allomorph of which stem final ‘s(ㅅ)’ is deleted in ‘s(ㅅ)’ irregular predicator is not the case that stem final ‘s(ㅅ)’ is directly deleted. Rather it is the case that the ‘z(ㅿ)’ is deleted in the form of ‘-zeu(ᅀᅳ)’ which was created by combining ‘s(ㅅ)’ with ‘eu(으)’. As a result, reconstruction occurred on the stem morph in the form of ‘-eu(으)’ combined with the vowel of endings ‘eu(으)’. Therefore ‘-eu(으)’ is the stem allomorph of the ‘s(ㅅ)’ irregular predicator. As in the case above, the stem allomorph of which stem final is changed into ‘l(ㄹ)’ in ‘d(ㄷ)’ irregular predicator is the changed form in which the final ‘d(ㄷ)’ is combined with the vowel ‘eu(으)’ and changed into ‘-reu(르)’. The stem final ‘d(ㄷ)’ in ‘d(ㄷ)’ irregualr predicator is not directly changed into ‘-l(ㄹ)’. As the reconstruction occurred into the form of ‘-reu(르)’ since it was combined with the vowel of endings ‘eu(으)’, ‘-reu(르)’ is the stem allomorph of the ‘d(ㄷ)’ irregular predicator.
