A more thorough explanation:

Definition: Ius praetorium is a Latin term that means "law of the praetors." It refers to the body of law that was developed through the edicts of the praetors in Roman law.

The ius praetorium was the mainspring of Republican reform. It was an important part of the Roman legal system and helped to shape the laws and regulations of the time.

For example, the edictum praetoris was a type of edict that was issued by the praetor. These edicts were used to clarify and modify existing laws, as well as to create new laws when necessary. The ius praetorium was also used to develop the jus honorarium, which was a body of law that was created by the praetors to supplement the existing laws.

Overall, the ius praetorium was an important part of the Roman legal system and helped to shape the laws and regulations of the time. It was developed through the edicts of the praetors and was used to clarify and modify existing laws, as well as to create new laws when necessary.
