What is the term for strengthening or supporting something with other evidence?

The term that refers to strengthening or supporting something with other evidence is "corroborate." When you corroborate a claim or an argument, you are providing additional information, data, or evidence that confirms or reinforces the original assertion. This process is crucial in areas like research, journalism, and legal proceedings, as it enhances the credibility of the information presented.

In many contexts, having corroborating evidence can significantly affect the acceptance or rejection of a claim, as it builds a more robust case for its validity. For example, in a legal context, corroborating witness testimonies or physical evidence can thoroughly substantiate a defendant's innocence or guilt, leading to a more informed decision by a judge or jury. Thus, corroboration plays a fundamental role in establishing truth and reliability in various fields.
