"Subjunctive Mood" in English Grammar

What Is Subjunctive Mood?

The subjunctive mood is a verb form in English that is used to express commands, suggestions, doubts, or hypothetical situations. By using the subjunctive mood, the speaker can convey a sense of obligation or necessity, or express ideas that are not necessarily rooted in fact.

The Present Subjunctive

The present subjunctive is used to express demands, suggestions, and necessity in the future. It is distinguished from other moods by its distinct verb form.

Present Subjunctive: Verb Form

The verbs in present subjunctive are finite but tenseless because when using the subjunctive mood, they often change form. The main verb of a subjunctive clause is always in its base form. Here are the changes:

am/is/are → Be

Example

You are confident. → I suggest that you be confident.

As you can see, 'are' in the declarative mood is changed to 'be' in the subjunctive mood.

has → have

Example

She has an English degree. → I suggest she have an English degree.

'Has' in the declarative mood is changed to 'have' in the subjunctive mood.

verbs in the 3rd person singular → the '-s' is omitted

Example

He exercises every day. → I suggest he exercise every day.

Here, the '-s' in the 3rd person singular verb 'exercises' is omitted when it's used in the subjunctive mood.

Tip!

In informal English, 'that' is commonly omitted from sentences with subjunctive mood.

Example

It's important that they be prepared. → It's important they be prepared.

Present Subjunctive: Common Verbs

Mandative verbs commonly trigger use of the subjunctive mood in the clause that follows them. These verbs express a sense of necessity or obligation. The following is a list of some verbs that commonly need a verb in the subjunctive mood after them:

suggest

demand

recommend

order

command

insist

ask

instruct

arrange

require

Example

Mike insisted that the price go higher.

Remember, in the subjunctive mood the verbs are not conjugated into third person singular form.

Sarah demanded that she be free.

Present Subjunctive: Common Adjectives

The following is a list of some adjectives that are commonly complemented by a verb in the subjunctive mood. These adjectives are often used in 'It is + adj + (that)' structure:

important

necessary

essential

vital

crucial

obligatory

urgent

desirable

imperative

Example

It is important that you be there.

It is essential that he listen to me.

Tip!

In English, we normally do not encounter a negative subjunctive sentence. The subjunctive mood is usually used in an affirmative construction.

Example

I suggest that he be early. (Not 'I suggest that he not be late.')

Alternative Structures

If you prefer not to sound formal, you can use:

Example

It's important that she be there. → She should be there.

Example

It's important that she be there. → It's important for her to be there.

The Past Subjunctive

To discuss unreal or improbable situations in the past, present or future, we can use the past subjunctive. Because of the non-factual nature of the ideas expressed using this structure, this use of the subjunctive mood is sometimes called irrealis mood.

Past Subjunctive: Verb Form

When talking about the present or future, the past subjunctive form of all verbs is their past simple form. The past subjunctive form of 'be' is 'were' for all persons, regardless of whether the subject is singular or plural. Although sometimes 'was' might be used in these structures (especially in informal contexts) the general rule of thumb is to use 'were' in all cases.
However, if we're talking about an unreal or hypothetical situation in the past, the past perfect form of the verb is used in subjunctive sentence.

Example

I wish I could travel the world.

It's time you were compensated for your troubles.

Past Subjunctive: Triggers

The past subjunctive is used with:

Conditional type II sentences (only past simple)

Example

If I were a parent, I would love my kid unconditionally.

Remember not to use 'was' for third and first person singular.

Conditional Type III sentences (only past perfect verbs)

Example

If I had known you were in town, I would have made time to meet you.

'It's (about/high) time...'

Example

It's about time you cleaned your room!

An expression used to emphasize that something should have occurred a long time ago.

The verb 'Wish'

Example

I wish I were taller.

I wish I had given you a chance.

This expresses an unrealized wish in the past.

'If only'

Example

If only I knew her name.

If only you had told me the truth.

'I'd rather'

Example

Well, I'd rather you didn't smoke in here.

Used to show that you prefer to have or do one thing more than another.

I'd rather you had come later.

'As if/As though'

Example

It's my birthday. As if you didn't know!

They have a similar meaning and are used to talk about an imaginary situation or a situation that may not be true but is likely or possible. 'As if' is more common than 'as though.'

He acted as if he had never met me.

Tip!

When discussing a situation that is probable or real, it is possible to use the present tense after 'as if/though.'

Example

It sounds as though you're having a great time.

In this case, we mean 'You are probably having a great time.'

Review

The subjunctive mood indicates situations that are not real and are hypothetical. In addition to that, it presents suggestions, necessities, or obligations. Subjunctive clauses are distinguished by their verb forms.

am/is/are → be

You are confident. → I suggest that you be confident.

She has an English degree. → I suggest she have an English degree.
