A more thorough explanation:

Definitio

Definitio is a word that comes from Latin and is used in civil law. It has three meanings:

1. A definition or explanation of something.
2. The establishment of a general rule.
3. A boundary.

• When a lawyer gives a definitio of a legal term, they are providing an explanation of what that term means.
• When a court makes a ruling, it can create a definitio that sets a general rule for how similar cases should be handled in the future.
• A definitio can also refer to a boundary, such as the definitio of a property line.

These examples illustrate how definitio can be used in different ways in civil law.
