Pro-verb Phrases in the English Grammar

What Are Pro-Verb Phrases?

Pro-verb phrases are short words or expressions that replace the verb or verb phrase.
As a type of pro-form**, pro-verb phrases refer back to an antecedent and rely on it for meaning rather than having a sense of their own.

English Pro-Verb Phrases

Here is a list of common words that can act as pro-verb phrases in English:

1.

So

2.

Do

4.

The Particle 'To'

So in Pro-verb Phrases

"So" is one of the most common pro-verb phrases in English which shows agreement between two actions.

"So" + Modals and Auxiliaries

'So' might be followed by 'be' as a main verb, as well as 'modal verbs' and 'auxiliary verbs' to avoid repeating a verb phrase, especially in short responses with pronoun subjects. If the sentence does not have any modal or auxiliary verbs, the supporting auxiliary "do" is added after "so".
When 'so' is used in this way, the verb and subject are inverted and there is no need to repeat the main verb. For example:

A:

I'm studying tonight.

B:

So am I. (I am studying tonight, too.)

C:

They all joined the new gym.

D:

After three weeks so did he! (after three weeks he joined the gym too.)

"So" in Exclamatives

In exclamative responses, 'so' is commonly used as a substitute for the verb before the subject and verb 'be', modal, or auxiliary verbs. In this case, no inversion is necessary. For example:

A:

We're out of cookies.

B:

Oh, so we are!

C:

I can bake you a cake.

D:

So you can!

"Do" as Pro-verb Phrase

"Do" is commonly used as an auxiliary to form a pro-verb when the antecedent verb phrase has no auxiliary, or when "do" is used in the antecedent as auxiliary for negation. Look at the examples.

Example

She plays the piano, and her brother does too.

She works harder than he does.

They didn't complete the project, but we did.

"Do So" as a Pro-verb Phrase

'Do so' is used to refer to an action already mentioned. For example:

Example

She asked him to leave, and he did so.

He claimed he could fix the car, but he failed to do so.

"Nor", "Neither", and "Either" with "Do"

Adverbs like 'not … either', 'nor' or 'neither' can be used in combination with "do" when the antecedent is a negative verb phrase. For example:

A:

I don't think she'll be coming to the party.

B:

Nor do I.

B:

Neither do I.

B:

I don't either.

"Do It" and "Do That" as Pro-verb Phrase

'Do it' is used when the subject is different from the subject of the antecedent verb phrase to avoid repeating the whole clause. For example:

A:

He accidentally sent a message to the wrong person.

B:

I do it all the time. (I send a message to the wrong person all the time.)

'Do that' is used to refer back to deliberate actions because it is more emphatic. For example:

A:

Let's eat out tonight.

B:

Let's not do that.

A:

I want to take a break from all that and go on a trip.

B:

I really think you should do that.

The Particle 'To' as Pro-verb Phrase

A to-infinitive consists of the particle 'to' plus a bare infinitive. Since the bare infinitive verb carries the meaning of the verb, the particle 'to' can act as a pro-verb to avoid repeating the verb. Take a look at the examples:

A:

Make up your bed and brush your teeth.

B:

I don't want to (make up my bed and brush my teeth).

C:

What did he say?

A:

He refused to make up his bed and brush his teeth when I told him to (make up his bed and brush his teeth).
