Forming a negative sentence with a verb depends on the language you’re using. Here’s how it works in English:

1. Use “not” with auxiliary verbs: In English, negative sentences often use an auxiliary verb (like “do,” “is,” “are,” “has,” “have”) combined with “not” or a contraction like “isn’t” or “don’t.”

   • Simple Present: “I do not (don’t) like broccoli.”
   • Simple Past: “She did not (didn’t) go to the party.”
   • Present Continuous: “They are not (aren’t) coming to the meeting.”
   • Past Continuous: “He was not (wasn’t) working yesterday.”

2. Use “not” with modal verbs: Modal verbs (like “can,” “will,” “should”) also use “not” to form negatives.

   • “I cannot (can’t) swim.”
   • “She will not (won’t) attend the class.”

3. Use “not” with the verb “to be”: When “to be” is the main verb, you simply add “not.”

   • Present: “He is not (isn’t) happy.”
   • Past: “They were not (weren’t) ready.”

In each case, the placement of “not” or its contraction is crucial for creating the negative form.
