Explanation
Verification is an extra or final bit of proof that establishes something is true. To verify something is to make sure it's correct or true, so verification is an action that establishes the truth of something. Checking an ID is a verification of your age. Your bank will often ask for part of your social security number as verification of your identity. Scientists do research to establish verification for their theories. In all cases, verification is like a stamp of approval.
