Yeah, I could tell. It seemed like there was a lot of invalidation happening.

Root Explanation

Invalidation → It is formed from "in-" (meaning not) and "validus" (meaning strong or valid) and the suffix "-ation" (indicating a process or action). The word "invalidation" refers to the process of making something not valid or not strong.

Memory Tip

Think of 'not' ('in-') making something 'valid' ('validus') — that's why invalidation means the process of making something not valid.
