In negative sentences with "did", we always use the base form of the verb (not past tense). So: ✅ "I did not sing" (Correct – base form after "did") ❌ "I did not sang" (Incorrect – "sang" is past tense, which is wrong after "did") ❌ "I does not sing" (Incorrect – "does" is used with he/she/it, not with "I")
