What is the difference between a fact and an opinion?

The distinction between a fact and an opinion is primarily rooted in the nature of their verification. A fact is a statement that can be proven true or false through evidence or measurable data. For example, stating that "The Earth revolves around the Sun" can be verified with scientific data. In contrast, an opinion reflects a personal belief, feeling, or judgment that is subjective and cannot be universally verified. For instance, saying "Chocolate ice cream is the best flavor" is purely a matter of personal taste and varies from person to person.

By recognizing that facts can be tested and validated while opinions are based on individual perspectives, one can better understand how to distinguish between objective realities and subjective interpretations in discussions or writings.
