Abstract
This paper aims to illustrate the mechanism of the creation of styles in written language through the works of Santo Kyoden. Causative forms, -te-forms of verbs and potential expressions employed in yomihon, gokan, kibyoshi and sharebon are analyzed from the perspective of 'writer design' and the following characteristics of Kyoden's styles are identified: (1) Kyoden sets the basic variety for each work and uses the forms which belong to the variety for the most part. (2) In each work, Kyoden sometimes style-shifts to forms which usually belong to other varieties in response to such factors as the mode of the passage (descriptive vs spoken) and social attributes of the characters (gender, age, class etc.). Kyoden also shifts to the forms of other varieties for the purpose of the creation of social, psychological and discourse effects.
