Notes on Meaning

The word unalterability strongly emphasizes a complete resistance to any form of change, alteration, or amendment. It is a formal term typically used in academic, legal, scientific, or philosophical discourse to describe absolute constancy. It differs from words like "stability" or "durability," which imply resistance to change but not an absolute impossibility of it.
