Hohfeld developed a theory of jural relations to clarify legal concepts like rights, duties, privileges, and powers. He identified 8 fundamental concepts - rights, privilege, power, immunity, no-rights, duty, disability and liability - and arranged them as "jural opposites" and "jural correlatives". For example, rights have a correlative duty, while privilege is the opposite of duty. His framework aimed to bring clarity to legal problems by distinguishing concepts often confused as rights, like liberties which are actually privileges. This theory provides jurists an important tool to accurately understand and solve complex legal issues.
