Etymology
The base meaning “beginning” makes original something belonging to the first stage. In this sense, it describes what was present at the outset rather than something added or developed later.
In context
A codisil is a legal document that makes changes or additions to your existing will. When it's done correctly, it becomes part of your original will and holds the same legal power.
