ADDITION TO REMARKS (so do I, neither do I, etc.)

To add something to a remark is known as addition. Additions are mostly done at the end of a remark to beautify the sentence or to confirm what is said before. To do this we do not repeat the entire remark/sentence the other person says; instead, we use some Additions to give our opinion of the topic of discussion. See the following to understand this.

I’m going to invite her for lunch tomorrow. — So am I.

[In this I’M GOING TO INVITE HER FOR LUNCH TOMORROW is the remark and SO AM I is the addition.]

There are two kinds of additions to remarks, which are made understood below. Note that the subject of addition and remark is different since they are not said by the same person.

1. AFFIRMATIVE ADDITIONS

A) Affirmative Additions to Affirmative Remarks

Affirmative Additions to Affirmative Remarks are made with:

a) I’m going to invite her for lunch tomorrow. — I’m too/also.
= I’m going to invite her for lunch tomorrow. — So am I.

b) Mohan would like it and Rahul would too/also.
= Mohan would like it and so would Rahul.

c) Sohan likes to play cricket and Pankaj does too/also.
= Sohan likes to play cricket and so does Pankaj.

[Verb LIKES of the remark is in the Present Simple Tense, the helping verb of this tense is DO/DOES.]

d) They came on time. We did too/also.
= They came on time. So did we.

[Verb CAME of the remark is in the Past Simple Tense, the helping verb of this tense is DID.]

e) I dislike this book, and they do too/also.
= I dislike this book, and so do they.

f) Hari and Sohan are coming. Mahima is too/also.
= Hari and Sohan are coming. So is Mahima.

B) Affirmative Additions to Negative Remarks

Affirmative Additions to Negative Remarks are made with:

a) Sohan hasn’t ridden a horse ever. — But Rahul has.
b) She doesn’t like to watch movies but her husband does.
c) The horse wasn’t hurt but the rider was.

2. NEGATIVE ADDITIONS

A) Negative Additions to Affirmative Remarks 

Negative Additions to Affirmative Remarks are made with:

a) He can go to swim but I can’t.
b) He is a writer but I’m not.

[Contracted form of I AM NOT is I’m not (not I amn’t).]

B) Negative Additions to Negative Remarks

Negative Additions to Negative Remarks are made with:

a) Mohan never goes to cinema, neither does his wife.
= Mohan never goes to cinema, nor does his wife.

b) Reena doesn’t have a purse. — Neither do I.
= Reena doesn’t have a purse. — Nor do I.

IMPORTANT NOTES

1. Sohan goes for a walk daily and Pankaj does too/also.

[Verb GOES of the remark is in the Present Simple Tense, the helping verb of this tense is DO/DOES.]

2. They came on time. We did too/also.

[Verb CAME of the remark is in the Past Simple Tense, the helping verb of this tense is DID.]

3. When there is no helping verb in the remark, and the main verb is BE (is/am/are/was/were), the helping verb of the addition is also BE (is/am/are/was/were); e.g.

Ravi is a poet, Mahima is too/also.

NOTE: Likewise When there is no helping verb in the remark, and the main verb is HAVE (has/have), the helping verb of the addition is also HAVE (has/have); e.g.

Ravi has a car, Mahima has too/also.
