Root Explanation

Invariability → It is formed from "in-" (meaning not), "variabilis" (from Latin, meaning changeable), and "-ity" (meaning the state or quality of). The word refers to the state of being not changeable or unchanging.

Memory Tip

Think of 'not' ('in-') being combined with 'changeable' ('variabilis') to remember that 'invariability' means the quality of being unchanging.
