Substantiation is the act of providing evidence to support a claim or statement, proving its truthfulness. It's like showing your work in math class to prove your answer isn't just a guess. Think of it as the backbone of any argument or theory, adding credibility and weight. Without substantiation, opinions are just opinions, not facts. Imagine a detective gathering clues to build a case; each piece of evidence is a form of substantiation. It's what separates a rumor from a confirmed report. Basically, it's the difference between saying you aced a test and showing the actual grade.
