Negative sentences in English are just sentences that show something is NOT happening or NOT true. You usually make them by adding words like “not”, “don’t”, “doesn’t”, “didn’t”, “isn’t”, “aren’t”, depending on the tense. Here’s how it works in a simple way: Present simple We use don’t or doesn’t I don’t like tea He doesn’t go to school on Sunday Past simple We use didn’t I didn’t see him yesterday She didn’t go to the party Present continuous We use am not / isn’t / aren’t I am not working now She isn’t sleeping They aren’t coming Easy trick to remember If there is no “be verb” (am, is, are), use don’t/doesn’t/didn’t If there is a “be verb”, just add “not” after it
