What is what does substantiate means?

Substantiate means to provide evidence or support for a claim, argument, or statement to prove its accuracy, truth, or validity. It involves presenting factual information, data, examples, or statistics that strengthen or confirm the argument or hypothesis being made. The process of substantiating an assertion requires a careful analysis of the available evidence and a clear, concise presentation of the findings. It is an essential step in critical thinking and reasoning, as it helps to ensure that conclusions are based on sound evidence. In legal or academic contexts, substantiation is often required to establish the credibility of a claim or argument.
