On Fuzzy Of Semantic When Concepts Expressed By Words Appeared

The fuzziness of semantics is an important issue concerned by scholars of home and abroad, words to express the fuzziness of concept is an important part of language logic study. Words to express the semantic fuzziness of concept mainly refers to the course of words to express concept as the things generic division are not clearly which caused the uncertainty on judge, or about this and that, neither this nor that of generic boundary or properties state when people know things. The fuzziness is mainly reflected in two aspects, that is fuzziness of words to express concept's logic character, and the intermediate link's when fuzziness of words to express concept. Because the fuzziness of concept and word is meaning's fuzziness in essence, studying the fuzziness of words to express concept must analysis from the parts of speech and glosseme two sides, fanction words don't express concept ,because it only has garmmatical meaning and no lexical meaning, so it's outside the scope of our study, this paper mainly studies on notional words, especially nouns, verbs, adjectives and other notional words, and key investigation ploysemy, synonyms and antonyms and other glosseme exhibits meaning's fuzziness on the course of expressing concept from the point of glosseme.The cause of semantic fuzziness produced mainly reflected in three aspects: first, the difference of objective things generating pictures. Objective things reflected by subject have a course of generating pictures. Objective things which people known reflect it's"figure"through people's eyes and brain, however the"figure"has already distorted in some extent through these media, so it appeares difference, and the objective things which we understand has appeared semantic fuzziness. It's also understood through Frege's cognitive triangle theory. Second, the limitation of subject's ability of cognitive. To reflect objective things correctly, at first we must dependence on subject's cognitive ability and knowledge range. The difference of subject's cognitive ability leads to the difference of object's cognitive, and appeare semantic fuzziness to subjective cognition. Third, expression ability's limitation of language tools. The boundless universe are complex, but linguistic signs are limited, scanty language tool can not accurately express all things, therefore, when words express the concept ,it appeares semantic fuzziness in different degree. Subjective and objective factors will product some influences on semantic fuzziness which appeares when words express the concept, they exist some causality, and they play a role alltogether, therefore, we must fully consider above the three factors, and can not separate and perorate from one aspect alone. In the speech communication, correct understanding and ingenious application the features of words to express the concept's semantic fuzziness can make the language more formal ,more flexibility, both complete the communication task, and make readers get enjoyment of beauty to a certain extent.
