so am I, neither do they, etc
so + auxiliary + subject
We can use so to mean ‘similarly, also’, before auxiliary verb + subject. The structure is used to answer or add to what came before. Note the word order.
- Louise can dance beautifully, and so can her sister.
- ‘I’ve lost their address.’ ‘So have I.’
The same structure is possible with non-auxiliary be and have.
- I was tired, and so were the others.
- ‘I have a headache.’ ‘So have I.’
After a clause with no auxiliary verb, we use do/does/did.
- ‘He just wants the best for his country.’ ‘So did Hitler.’
We do not normally use a more complete verb phrase in this structure. We can say, for example, So can her sister, but not So can her sister dance.
A more informal alternative to So am I, etc is Me too.
- ‘I’m getting bored.’ ‘Me too.’ (not
I also.)
Neither do I, I can’t either, etc
We can use neither and nor as adverbs to mean ‘also not’. Neither and nor come at the beginning of a clause, and are followed by inverted word order (see here): auxiliary verb + subject.
- ‘I can’t swim.’ ‘Neither/nor can I. (not
I also can’t.)’ - Ruth didn’t turn up, and neither/nor did Kate. (not
… and Kate didn’t too.)
In American English, nor is not normally used after and.
We can also use not … either with the same meaning and normal word order.
- ‘I can’t swim.’ ‘I can’t either.’
- Ruth didn’t turn up, and Kate didn’t either.
In very informal speech, me neither (and occasionally me either, especially in American English) can be used instead of I …n’t either.
- ‘I can’t swim.’ ‘Me neither.’
Only one negative word (not or neither) is necessary to give a negative meaning.
- Neither did Kate
or
Kate didn’t either. (notNeither didn’t Kate) orKate didn’t neither
For the pronunciation of either, (see here).
For the pronunciation of neither, (see here).
For neither … nor, (see here).
For other uses of either and neither, (see here).
For not … or and not … nor, (see here).
so + subject + auxiliary: So it is!
So is used in another short structure before subject + auxiliary verb (note the word order) to express surprised agreement.
- ‘It’s raining.’ ‘Why, so it is!’
- ‘You’ve just put the teapot in the fridge.’ ‘So I have!’
