A more thorough explanation:

Term: Salva Substantia
Definition: Salva substantia is a legal term that means preserving the substance of something. It is often used in Roman and civil law to refer to the idea that the essential part of something should remain intact. For example, if someone has a right to use a piece of property, they cannot use it in a way that destroys its essential nature. This means that the property must be used in a way that preserves its substance.
Example: If someone has a right to use a car, they cannot use it in a way that damages the engine or other essential parts. They must use the car in a way that preserves its substance. This means that they can use the car for transportation, but they cannot use it for racing or other activities that could damage the car. The idea of salva substantia is important in legal agreements because it helps to ensure that property is used in a responsible and sustainable way.
