同音語の研究

It is said that there are many homonyms obstructing communication in modern Japanese. The degree and characteristics of the obstruction are not uniform, however, the purposes of this study were to determine the real degree to which the semantic ambiguity of homonyms occurs, to analyze the factors working to distinguish homonyms, and to see what problems are encountered in the promotion of communication.There is considerable ambiguity in some homonyms and not in others. We therefore classified homonyms first, laying down the following criteria: (1) sociological differences, (2) grammatical differences, (3) idiomatic or non-idiomatic, (4) differences in tones, (5) productivity, and (6) frequency.Besides these characteristics of homonyms themselves, the discrimination of homonyms is influenced by the users\u27 knowledge. On this point we made an experiment using students of high schools and universities. We found that all homonyms can be discriminated to some extent either by characteristics of the words themselves (for example, part of speech, idiomatic usage, productivity, word-construction, etc.), by phase differences, or by context. It was also made clear that few homonyms except homonymic synonyms have no clue of discrimination. It was also established that the problems of homonyms greatly depend upon the readers\u27 age and experience.The latter half of this book is devoted to a word list containing 7,803 homonyms.This survey was carried out by MATUO Osamu, ITIKAWA Takasi, ÔKUBO Ai and TANAKA Akio
