Formula:
[Nor/Neither] + auxiliary verb + subject

| Neither have they | have | they | “They haven’t arrived. Neither have they.” |
| Nor did he | did | he | “He didn’t reply. Nor did he.” |
The auxiliary verb you choose must match the tense and modal of the original statement. If someone says “I couldn’t finish it,” you respond “Nor could I” or “Neither could I.”
