A contrastive analysis of English and Korean sentences, including error analysis, is presented. The study focuses on word order, comparing the languages' similarities and differences with the objective of understanding better how the structural differences inhibit the progress of the Korean learner of English. The English data are derived from reference books and some colloquial expressions. The Korean data are drawn from the author's standard Korean dialect. The analysis begins with an outline of special features of Korean grammar and a definition of word order, and proceeds to parallel descriptions and discussion of the roles of modifiers and prepositions, basic sentence patterns, sentence types, the passive voice, introductory pronouns, numerical expressions, expressions of degree, some idiomatic expressions, and some passive and causative expressions in the two languages. Both structural and transformational approaches to the grammars are used in the comparison. It is concluded that structuralism is useful for the actual teaching material, and transformational-generative grammar is useful for analysis of the semantics of the sentence and its function, which are neglected in structuralism. The use of contrastive analysis for assisting Korean speakers in learning English is recommended in addition to continued exposure to real speaking situations in English. (MSE)
