immutábilis

Immutábilis is a term used to describe the quality of being unchangeable or resistant to alteration. The form surfaces in Latinized scholarly usage and is adopted in modern discussions as a stylized label for immutability across domains, especially philosophy, computer science, and information governance.

Etymology: The word derives from Latin immutabilis, from immut- 'not change' plus -abilis 'able to be'. The form immutábilis is encountered in some manuscripts and contemporary texts as a variant or coined term.

In philosophy, immutability refers to the idea that certain properties, laws, or essences do not change across possible histories. Debates center on whether universals or foundational laws are truly immutable and how such immutability interacts with change in the material world.

In computing, immutability denotes objects or data that cannot be changed after creation. Immutable objects simplify reasoning about programs and enhance thread safety. Common examples: immutable strings in many languages, persistent data structures in functional programming, and audit-friendly logs in distributed systems such as blockchain.

In information governance, immutability is used to describe records or logs that are appended but not altered, to preserve integrity and traceability over time.
