Kwon Young-Moon. 1999. Meaning Aspects of Complex Expressions. Studies in Modern Grammar 16, 199-219. The purpose of this study is to examine the meaning aspects of complex expressions. Complexity in thought tends to be reflected in complexity of expression. A complex expression has added morphemes or cannot neutralize in meaning in contexts that the almost equivalent expression can. Iconic motivation is reflected in linguistic expressions such as followings: singular - plural, affirmative negative, male - female, present - nonpresent, state - change of state, noun - pronoun, adjective - adverb, positive - comparative - superlative, cardinal - ordinal, and so on. The complexity principle is based on cognitive factors such as attention, priority, mental efforts, and so forth. To structuralize language through conceptualization is cognitively efficient, and it helps us to communicate with each other efficiently.

Kwon Young-Moon. 1998. Context and Acceptability. Studies in Modern Grammar 13, 157-179. The purpose of this study is to investigate the acceptability or appropriateness of sentences or utterances in context. sentence is a grammatically arranged linguistic utterance made up of one word or more. Context means the grammatical word-order and the relation of words to other words in the syntactic text. And context plays an important role in determining the acceptability of utterances. Although some sentences are grammatical, they may not acceptable in the discourse context. Because most sentences are very heavily dependent on the contexts for their meaning and form. There are two majar factors which determine the word order of a given sentence. Firstly, sentences of a particular language are formed according to its syntactic tales. Secondly, a given sentence with its basic formation or word arrangement should be rearranged according to the discourse context to which the sentence belongs. Therefore, any description of language structure would be incomplete without taking account of various contextual factors.
