A Study of the ambiguity of coordinations in English

영어 등위구조의 중의성 연구

The purpose of this paper is to analyze the semantic ambiguity of coordination connected by 'and' in English and show a clear explanation for the meaning of the sentence. Two sentences which are connected by 'and' can be divided into the symmetric conjunction and the asymmetric conjunction according to its meaning. Especially, in order to explain the different meaning in the asymmetric conjunctions, we introduce the theory of presupposition and entailment, which provides the solution to the ambiguity in meaning. It can be said that presupposition and entailment can logically explain the meaning of natural language.
