What is the difference between a positive sentence and a negative sentence?

Sure, here's the difference between a positive sentence and a negative sentence:

Positive Sentence:

• A statement that is true.
• Indicates a fact or a state of being.
• Uses a positive verb, such as "is," "am," "are," or "was."

Negative Sentence:

• A statement that is not true.
• Indicates a fact that is not true or a state of being that is not present.
• Uses a negative verb, such as "is not," "am not," "are not," or "was not."

Here's an example of a positive sentence:

• The sun is shining today.
