英語 弱母音의 弱化와 消滅에 관한 硏究 = The Study on the Weakness and Deletion of the English Weak Vowels

다국어 초록 (Multilingual Abstract)

I have tried to find out the phenomena and the reason of the weakness and deletion of the English weak vowels by reviewing the studies and researchs of the English linguists.
The English vowels can be weakened and deleted when they come just in front of or just after the weak syllable, when they come at the end of the word which lost its importance through its historical process, when they get pressure by two strong syllables, when several weak vowels come consecutively and when they get affection by the vowel environment.
