The researcher has raised the following questions (i) How does a social group and its members have their own typical category member? Which social factors are responsible in the process of forming the typical member? At the end of the current paper , the researcher has drawn a conclusion for his this study. we can say that each social group has its own prototype(s) due to the differences that each society has .
