Root Explanation
Immutably → It is formed from "in-" (meaning not) and "mutabilis" (from Latin, meaning changeable). The word "immutably" means not able to be changed or unchangeable.
Memory Tip
Think of 'not' ('in-') being able to 'change' ('mutabilis') — that's why immutably means something that cannot change.
