The human body has many different parts.
Each of these parts forms a system connected to each other by functional relationships.
In the same way, two or more units of a society form a system by connecting with each other in a functional relationship.
According to Talcott Parsons, "a social system is a complex made up of parts that are in functional relationships with each other."
Definition of social system given to Sorakin:
"A social system is an organized group that has a complex set of social norms that establish the rights, duties, social positions, functions, roles, as well as the behavior of its members and the behavior of members of the wider community outside the group."
In simple terms, social system is the system of interaction of individuals who play a role in a social place or social status.
