Neither did she means the same as She didn’t either.

The phrases “Neither have,” “So have,” “Either have,” and “Nor have” are used in different grammatical contexts in English. Here’s a breakdown of how each one is used:

1. Neither have

• Used to show agreement in a negative statement.
• Structure: Neither + auxiliary verb (have) + subject
• Example:
  • A: “I haven’t finished my homework.”
  • B: “Neither have I.” (I also haven’t finished my homework.)

2. So have

• Used to show agreement in a positive statement.
• Structure: So + auxiliary verb (have) + subject
• Example:
  • A: “I have visited Paris.”
  • B: “So have I.” (I also have visited Paris.)

3. Either have

• Used in conditional or comparative sentences, but not commonly used alone in modern English.
• Example:
  • “If you haven’t seen it, I haven’t either.”
    (This means: Neither of us has seen it.)

4. Nor have

• Used after a negative statement to extend the negativity to another subject.
• Structure: Nor + auxiliary verb (have) + subject
• Example:
  • “I haven’t been to the new restaurant, nor have my friends.”
    (Neither I nor my friends have been to the new restaurant.)

Key Notes:

• Neither and nor are used for negatives.
• So is for positives.
• Either is rare on its own but often used in a paired structure (e.g., “I haven’t either”).
