A more thorough explanation:

Definition: Formulae (pronounced "for-my-lee") are model pleas created by the praetor in Roman law. These were adapted by magistrates in civil suits to help the judex (judge) who had to try the issue. The formulae were adjusted to fit the specific circumstances of each case.

Examples: If someone was suing for damages in a civil case, the magistrate would use a formula to help the judge determine the appropriate amount of compensation. The formula would take into account factors such as the severity of the harm caused and the financial situation of the parties involved.

Another example would be if someone was seeking to recover property that had been wrongfully taken from them. The magistrate would use a formula to help the judge determine whether the plaintiff had a valid claim to the property and what actions should be taken to remedy the situation.

These examples illustrate how formulae were used in Roman law to provide a standardized approach to resolving legal disputes. By using formulae, magistrates could ensure that cases were handled fairly and consistently, regardless of the specific circumstances involved.
