Also / Too / As well Either So + auxiliary + subject Neither + auxiliary + subject Exercises
Before this page: If you haven't seen the basic short answers "Me too" and "Me neither" yet, start there. This page covers the same idea, but with full sentences and, in two of the four patterns, auxiliary inversion.

Also / Too / As well — agreeing with a positive, no inversion

The simplest way to agree with something positive. No inversion — the word order stays exactly like a normal sentence, you just add also, too, or as well.

PositionExample
also — mid-position, before the main verb A: "I speak French." B: "I also speak French."
too / as well — end of sentence A: "I speak French." B: "I speak French too / as well."
These agree with a positive statement only: "I like coffee." → "I like it too." ✓. Never use also/too/as well to agree with a negative statement — that's what "either" is for (next section): ✗ "I don't like coffee." → "I don't like it too."

Either — agreeing with a negative, no inversion

The negative counterpart of also/too/as well. No inversion — normal word order, just add either at the end of the sentence.

Original statementAgreement
A: "I don't like coffee."B: "I don't like it either."
A: "I can't swim."B: "I can't either."
A: "She hasn't finished."B: "He hasn't either."
Either agrees with a negative statement only: It's the mirror image of too: ✓ "I don't like it either." ✗ "I like it either." (wrong — use "too" for a positive statement)
Don't confuse with either...or: This "either" (agreement) is a different use from "either...or" (choice between two options, e.g. "either the bus or the train"). Same word, two separate jobs.

So + auxiliary + subject — agreeing with a positive, with inversion

Also used to agree with a positive statement, but this pattern uses inversion: the auxiliary comes before the subject, just like in a question.

Structure: So + auxiliary + subject
A: "I love this song." B: "So do I."
Original statementAgreement
I am tired.So am I.
She can swim.So can he.
They have finished.So have we.
He likes jazz.So does she.
We went to the beach.So did they.
Choosing the auxiliary: Match whatever auxiliary the original sentence uses (be/have/can/will…). If the original has no auxiliary — a simple present or past verb — use do/does/did, exactly like forming a question.

Neither + auxiliary + subject — agreeing with a negative, with inversion

The inversion counterpart of "either." Used to agree with a negative statement — same inversion pattern as "So", but the sentence itself is already negative, so don't add a second "not".

Structure: Neither + auxiliary + subject
A: "I don't like olives." B: "Neither do I."
Original statementAgreement
I'm not hungry.Neither am I.
She can't drive.Neither can he.
They haven't arrived.Neither have we.
He doesn't like spiders.Neither does she.
Nor works the same way: "Nor" is an alternative to "Neither" in this pattern: "I can't cook." "Nor can I." Both are correct; "Neither" is more common.
Common mistake — double negative: ✗ "Neither don't I." The auxiliary after "Neither" is never negative — the word "Neither" already carries the negative meaning: ✓ "Neither do I."
