Root Explanation
Tested → It is formed from "test" (from Latin *testari*, meaning to witness or to prove) and the suffix "-ed" (indicating past tense). The word "tested" means that something has been proven or witnessed in the past.
Memory Tip
Think of 'test' as proving something, and the '-ed' shows that it has already happened. So, when something is 'tested', it means it has been proven in the past.
