So do I, neither do I: agreeing in short
The rule in short
How to say that something is true for you too with short replies like so do I, so am I and neither can I, how to choose the right verb, and how to say that it is not true for you.
The reply has three parts: so or neither, a helper verb, and the subject. For agreeing, the helper verb comes before the subject: So do I, Neither can Tom.
You do not choose the helper verb freely. Look at the verb in the first sentence and copy its type (you will use the same idea later in question tags):
| The first sentence has… | Positive sentence → so | Negative sentence → neither |
|---|---|---|
| am / is / are | I'm busy. — So am I. | I'm not sure. — Neither am I. |
| was / were | I was at home. — So was I. | I wasn't there. — Neither was I. |
| an ordinary verb, present | I like cats. — So do I. | I don't watch TV. — Neither do I. |
| an ordinary verb, past | I got up early. — So did I. | I didn't call. — Neither did I. |
| have / has + past participle | I've paid. — So have I. | I haven't paid. — Neither have I. |
| can / could | I can ski. — So can I. | I can't ski. — Neither can I. |
| will / would | I'll help. — So will I. | I won't tell anyone. — Neither will I. |
An ordinary verb has no helper of its own, so the reply brings in do, does or did, just as a question or a negative does (see present simple questions and negatives). When have is the main verb (I have a bike), it is an ordinary verb too, and the usual reply is So do I. With have got the helper is have: I've got a bike. — So have I.
A few more points.
- The helper verb matches its own subject, not the first speaker's: I play tennis. — So does Anna. / Anna plays tennis. — So do I.
- Neither is already negative, so the helper after it is positive: Neither do I, not Neither don't I.
- Nor means the same as neither and works the same way: Nor do I. It is a little more common in British English.
- Never also makes a sentence negative: Tom never takes the bus. — Neither do I.
- In speech the stress falls on the last word: so do I, neither can Tom.
Me too and me neither. Me too answers a positive sentence and Me neither a negative one. They are very common in everyday speech and perfectly correct, but they do not show the verb, and they only talk about you. (Some American speakers also say Me either in the same way.) As a reply on its own, I too sounds formal or old-fashioned, so in conversation say Me too or So do I.
When it is not true for you. Then you reply with the subject and the opposite form of the helper verb, often after Really? or Oh: I hate spiders. — Really? I don't. / I'm not ready. — Oh, I am. / I can't ski. — I can. A positive reply like I am or I have keeps the full form at the end, never I'm or I've.

Answer key
A. After a positive sentence the reply starts with so. After a negative sentence (with not, n't or never) it starts with neither.
- So
- Neither
- Neither
- So
B. Copy the type of verb from the first sentence: am/is/are → be, an ordinary verb → do/does/did, have + past participle → have/has, can → can, will → will. Then match it to the new subject.
- am
- do
- did
- have
- does
- will
C. Me too agrees with a positive sentence. Me neither agrees with a negative sentence (with not, n't or never).
- Me too.
- Me neither.
- Me neither.
- Me too.
D. So / Neither (or Nor) + a helper verb that copies the first sentence + the subject: So do I, Neither can Tom, So are we.
- So do I
- Neither do I / Nor do I
- So was Anna
- Neither can Tom / Nor can Tom
- Neither have I / Nor have I
- So are we
E. To disagree, use I + the opposite form of the helper verb: a positive sentence gets I don't, I'm not, I can't; a negative one gets I do, I am, I can, I have.
- I don't
- I am
- I can
- I did
- I have
F. And so / and neither + helper verb + subject: Anna loves jazz, and so does Tom. The helper verb copies the first verb and comes before the subject.
- Anna loves jazz, and so does Tom. / Tom loves jazz, and so does Anna.
- Tom is good at drawing, and so am I. / I am good at drawing, and so is Tom.
- Neither did the other students.
- My parents can't skate, and neither can I. / I can't skate, and neither can my parents.
G. The second half copies the type of verb from the first half (be, do, have, can…), matches its own subject, and comes before that subject. So follows a positive sentence, neither or nor a negative one, and the verb after neither is positive.
- Tom is hungry, and so is Anna.
- I don't like tea, and neither does my brother. / I don't like tea, and nor does my brother. — After neither the verb is positive and matches the subject: neither does my brother.
- Anna went to the concert, and so did Tom. (✓) — This sentence is right: went is a past ordinary verb, so the second half uses did.
- My sister can drive, and so can I.
- Anna has never played golf, and neither has Tom. / Anna has never played golf, and nor has Tom. — Never makes the first half negative, so the second half needs neither or nor: neither has Tom.
- Tom wasn't at school today, and neither was Anna. (✓) — This sentence is right: wasn't is negative, so the second half has neither and the positive was.
- My brother lives near the river, and so does my sister. / My brother lives near the river, and so do my sisters. — My sister is one person, so the verb is does: so does my sister.
H. The reply copies the type of verb (am, did, have, will) and uses so after a positive sentence, neither after a negative one.
