What Is a Subjunctive Sentence? Subjunctive Mood in English Grammar

In daily English communication, we often use phrases like “I hope” or “I want” to express a wish or request. However, using the subjunctive mood adds sophistication to your language, helping you improve coherence and score higher in the IELTS Writing test. So what exactly is the subjunctive mood? How is it structured and used in English? Let’s find out with IDP!

The subjunctive sentence (or subjunctive mood) expresses wishes, suggestions, or hypothetical situations. It is commonly used to make polite requests or recommendations, without the force of a command.

Examples:

• Someone suggested that we play a party game to break the ice.

• It is necessary that the machines equip a monitoring device.

a. Subjunctive Sentences with Verbs

Structure: S1 + V1 + that + S2 + V2 + Object

• V1 is the main verb, conjugated based on the first subject (S1).

• V2 is always in the base form (infinitive without “to”).

Common verbs used in the subjunctive mood:

• advise, demand, prefer, require, insist, propose, stipulate, decree, order, request, urge, ask, command, recommend, suggest

Examples:

• I propose that we discuss this at the next meeting.

• He commanded that man go at once.

b. Subjunctive Sentences with Adjectives

Structure: It + to be + adjective + that + S + V(base form)

Common adjectives used in the subjunctive mood:

• important, necessary, obligatory, essential, recommended, mandatory, advisable, required, vital, suggested, proposed, imperative, crucial

Examples:

• It is recommended that you consult your doctor.

• It is essential that we present a united front.

a. Present or Future Hypothetical

Structure: S1 + would rather (that) + S2 + V(past simple)

Use "were" for all subjects with the verb “to be.”

Examples:

• I would rather that you didn’t smoke in the house.

• I would rather it were spring now.

b. Past Hypothetical or Regret

Structure: S1 + would rather (that) + S2 + had + V(past participle)

Examples:

• He would rather that she had accepted his proposal.

• She would rather that he had told her the truth from the beginning.

These phrases indicate that something should already have happened or should happen soon.

Structure:

• It’s time + S + V(past simple)

• It’s high time + S + V(past simple)

• It’s about time + S + V(past simple)

Examples:

• It’s time you started on your homework.
