Root Explanation
Evidential → It is formed from "evident" (from Latin "evidens", meaning clear or obvious) and the suffix "-ial" (meaning relating to). The word "evidential" refers to something that relates to or provides evidence.
Memory Tip
Think of something that is 'clear' or 'obvious' ('evident') and how it relates to 'evidence' — that's why evidential means relating to evidence.
