Subjunctive Mood in English: Rules and Exercises
The English subjunctive is small in form but powerful in meaning. It marks recommendations, requirements and situations treated as remote from fact. The key is to distinguish a demanded action from a reported fact.

Practise the formal base-form subjunctive explicitly. British English also permits should and, in some contexts, ordinary tense forms; those alternatives are not universally wrong.

What the subjunctive mood in English does
The subjunctive does not describe an event as an ordinary fact. It presents an action as required, recommended, desired or counterfactual. Modern English mainly preserves two visible patterns:
Mandative base form
trigger + that + subject + base verbThe chair insisted that every member be present.
Be and verbs without third-person -s reveal the pattern.
Irrealis were
if / wish / as if + subject + wereI wish the process were simpler.
Were marks distance from present reality, especially in careful formal English.
One policy, three formal patterns
Active: We recommend that every visitor wear a badge.
Passive: It is essential that the badge be displayed.
Negative: We request that visitors not enter the laboratory alone.
The base form stays the same after he, she and it. The British alternative “We recommend that every visitor should wear a badge” is also grammatical. A sentence with were to describes a remote condition, rather than a recommendation.
The mandative subjunctive after demands and recommendations
The mandative subjunctive uses the base form for every subject. It is common in formal, institutional and professional English, particularly after verbs, adjectives and nouns expressing necessity or influence.
| Trigger type | Common triggers | Subjunctive example |
|---|---|---|
| Verb | advise, ask, demand, insist, propose, recommend, request, suggest, urge | They recommended that the proposal be revised. |
| Adjective | advisable, essential, imperative, important, necessary, vital | It is essential that each applicant provide evidence. |
| Noun | advice, demand, proposal, recommendation, request, requirement | The requirement that every device meet the standard remains. |
Third person: no -s
They insist that she attend.
They insist that she attends. when the meaning is a demand.
Be remains be
It is vital that he be informed. The form does not change to is or was.
Negative: not + base
We requested that the file not be shared. No form of do is added.
Passive: be + participle
The judge ordered that the evidence be excluded.
The were subjunctive for remote situations
The were subjunctive appears most clearly with I, he, she and it, where ordinary past agreement would use was.
Counterfactual conditions
Use were when imagining a present state that is not treated as fact.
If the assumption were correct, the figures would align.Wishes
Wish + were expresses dissatisfaction with a present state.
I wish the office were closer.As if / as though
The remote form signals that the comparison is doubtful or contrary to fact.
He speaks as though he were the sole authority.Remote condition with were to
Were + subject + to-infinitive can introduce a remote formal condition.
Were the policy to change, we would need new guidance.Register, regional alternatives and meaning contrasts
British should alternative
British English often uses should + base verb in mandative clauses.
They recommended that the report should be revised.Infinitive alternative
Many triggers also allow an object plus infinitive.
They advised us to postpone the launch.Fact or recommendation?
Compare the indicative with the mandative meaning.
She insisted that he was honest. = she strongly claimed a factShe insisted that he be honest. = she required honest behaviour
Fixed expressions
Some formulaic subjunctive examples survive as set phrases.
Be that as it may; so be it; far be it from me.English subjunctive exercises: guided practice
1. Complete formally: “The committee recommends that every submission ___ anonymised.” (be)
be anonymised. The recommendation licenses the base-form subjunctive; the passive is be + past participle.
2. Correct: “It is vital that each witness tells the truth.”
It is vital that each witness tell the truth. In a mandative reading, the base form has no third-person -s.
3. Negate: “They requested that the draft be circulated.”
They requested that the draft not be circulated. Place not before the base form; do not use doesn’t.
4. Choose fact or demand: “Mina insisted that the door was locked / be locked.”
Was locked means Mina claimed that locking was already a fact. Be locked means she demanded that someone lock it. Both are grammatical with different meanings.
5. Rewrite with formal remoteness: “If the supplier was to withdraw, production would stop.”
If the supplier were to withdraw, production would stop. You can also invert: Were the supplier to withdraw…
6. Explain the contrast: “If Dara was at the conference, she heard the news” / “If Dara were at the conference, she would present the paper.”
The first is an open question about a real past event, so was is indicative. The second imagines a remote present/future situation, so formal English uses counterfactual were.
