How is “Don’t” used in English? What are the rules of use of “Don’t”?

The word “don’t” is used in English in various ways to express negation or prohibition. Here are some common rules and guidelines for its usage:

  2. Subject-verb agreement: “Don’t” is typically used with the pronouns “I,” “you,” “we,” and “they.” When using “don’t,” the verb following it should be in the base form (infinitive) without the “to” particle. For example:
