You know, I've been thinking about the concept of inalterability in our lives.

That sounds deep! What made you bring that up?

Root Explanation
Inalterability → It is formed from "in-" (meaning not), "alterare" (meaning to change), and "-ability" (meaning the quality of being). The word "inalterability" means the quality of not being able to be changed or altered.
Memory Tip
Think of 'not' ('in-') being able to 'change' ('alterare') something — that's why inalterability means something cannot be changed.
