The purpose of this study is to identify character traits in Suvushun: from reality to idealism using descriptive- analytical method. First we examine conceptual aspects in the career of Simin Danshwar as the writer of Suvushun. Then, we explore her works and attitudes. Finally, development of main characters in Savushun is critically studied. The findings show that all elements of the story are interrelated including plot, action, character, dialogue, crisis, time and space. Action and character are more important elements. In one hand, the writer has tried to analyze the various aspects of characters in the novel of Suvushun. In the other hand, the relationships of other elements of the story are highlighted such as dialogue, time, space and scene and etc and realism and idealism are discussed because it is evident that the writer believes in characters “Yusof” and “Zari” and etc. Savushun is a combination of idealism and realism, yesterday and tomorrow so this helps its mystery, non-limited and mythology nature. Hence, some critics hold that it is sociologic. Some claims that it is historical and others say it is political. It is seen from different angles so it appears in different colors. However, its internal integrity and general order and coordination denote its unique result. According to Iranian mythology, Yusuf might be killed by an unknown killer or due to a lie in order that his loving son “Khosro” could establish justice in Iran and could abolish Turanian as the contemporary evils (Englishmen).
