To substantiate a claim is to do what?

To substantiate a claim means to provide evidence or proof that supports the validity of the claim. This process involves backing up a statement or assertion with verifiable details, facts, or data that lend credibility to what is being stated. Providing evidence adds weight and reliability to a claim, making it more convincing to others. In discussions, arguments, or academic writing, substantiating claims is crucial for persuading an audience and demonstrating that a particular assertion is grounded in reality. This practice is fundamental in various fields, including science, law, and academia, where accuracy and support for claims are essential.
