Here are some key aspects of "opinion":
* Subjective: Opinions are personal and can vary widely from person to person.
* Not always based on facts: Opinions can be influenced by emotions, biases, or incomplete information.
* Can be changed: As people learn more or have new experiences, their opinions can evolve.
Examples:
* "My opinion is that the new movie was terrible."
* "The doctor's opinion is that you should rest for a week."
* "Public opinion on the issue is divided."
It's important to distinguish between opinions and facts. Facts are objective truths that can be verified, while opinions are subjective beliefs.
