The subjunctive appears when English talks about wishes, demands, advice, necessity, or situations that are not real. The speaker is not presenting the action as a fact. The form shows attitude toward the action: someone wants it, expects it, imagines it, or treats it as important. Compare a normal statement like She is here with a subjunctive idea like I insist that she be here early. The second sentence focuses on requirement, not on a fact. The subjunctive is common in formal English and in patterns connected to Moods.

With be, the subjunctive form is were in unreal situations, even with I, he, she, and it. Say If I were you and She acted as if she were the boss. In the past, was is normal for simple facts, but were signals a special unreal meaning when the speaker talks about something imagined or impossible. The form appears after if, as if, as though, and in wishes. It is not tied to number or person in the way ordinary verb forms are.

After verbs such as insist, require, demand, recommend, and suggest, formal English often uses that + subject + base verb. The verb after the subject stays in its base form, without -s, to, or did. Say They demanded that he leave immediately and The doctor recommends that she rest. In less formal speech, many people use should or an ordinary tense, but the bare verb is the standard subjunctive pattern in formal writing and careful speech. This pattern is also common with verbs of authority and necessity, as in The manager insisted that the door be locked.

Bare verb after formal demands

Usage	Explanation	Example
Strong demand	Use the bare verb after verbs like demand when you want an official or forceful request.	The manager demanded that everyone leave early.
Firm recommendation	Use the bare verb after verbs like recommend when giving serious advice.	The doctor recommended that she rest for two days.
Formal insistence	Use the bare verb after verbs like insist when the speaker is pressing for a result.	They insisted that the team start on time.
Necessary requirement	Use the bare verb after verbs like require when a rule or authority says something must happen.	The school requires that students wear ID cards.
Serious urging	Use the bare verb after verbs like urge when you want to push someone to act.	We urged that he take the earlier bus.

Wish and if only describe a situation the speaker wants to change. For a present regret or unreal present, use the past form: I wish I had more time and If only he knew the answer. For be, use were: She wishes she were taller. For a past regret, use had + past participle: I wish I had studied harder. If only is stronger and more emotional than wish. These forms often appear when a speaker compares reality with a better, imagined situation.

Wish and if only for regrets

Usage	Explanation	Example
Present regret	Use wish plus past form to say the present is different from what you want.	I wish I knew the answer.
Past regret	Use wish plus had to regret a past event or action.	She wishes she had called sooner.
Strong present wish	Use if only plus past form for a stronger and more emotional present wish.	If only we had more time today.
Strong past regret	Use if only plus had to show deep regret about a past situation.	If only he had listened to the warning.

After as if and as though, English often uses past forms to show that the idea is unreal or only imagined. Say He talks as if he owned the place and She looked as though she had not slept. For be, formal English uses were: It seemed as if the room were empty. When the comparison is about a real or likely situation, ordinary present or past forms may appear, but the unreal form focuses on appearance, not fact. These phrases are common in descriptions and storytelling, where the speaker wants to show that something only seems true.

Unreal comparisons with as if

Usage	Explanation	Example
Unreal present comparison	Use past form after as if to describe something that is not true now.	He speaks as if he were the boss.
Unreal past comparison	Use had plus participle after as if to describe something that is not true in the past.	She looked as though she had seen a ghost.
Imagined state	Use past form after as though when a person or thing seems to have a false quality.	The room feels as though it were empty.
Imagined event	Use had plus participle after as though for a situation that only seems past and real.	They celebrated as though they had won the final.

After would rather, English uses the base verb when the subject of the second action is different: I would rather he stay and They would rather we leave now. When the subject is the same, the phrase is followed by would rather + base verb or an infinitive structure: I would rather leave now. The expression it’s time often takes a past form to show something should happen now: It’s time we left and It’s time he learned the truth. The past form here does not mean past time. It shows that the speaker wants action in the present.

Subjunctive patterns after preference words

Usage	Explanation	Example
Preferred present action	Use would rather plus bare verb when you want a different action now.	I would rather stay home tonight.
Preferred action for another person	Use would rather plus past form when you want someone else to do something different now.	She would rather he left before midnight.
Urgent timing	Use it is time plus past form to say something should happen now.	It is time we started the meeting.
Late correction	Use it is high time plus past form to sound stronger and more urgent.	It is high time you took a break.

Verbs of recommendation and influence often use that + subject + base verb. The most common formal verbs are suggest, advise, urge, recommend, insist, demand, and request. Say I suggest that he take the earlier train and The nurse advised that the patient stay home. In everyday English, speakers may also use should: I suggest that he should take the earlier train. Both patterns are possible, but the bare verb is the more formal subjunctive form. This pattern works well in official notices, workplace instructions, and careful writing. It is closely connected to the kind of language used in Imperative, but it keeps the request inside a clause.

Formal that clause advice patterns

Usage	Explanation	Example
Suggestion after suggest	Use that plus bare verb after suggest in formal English.	I suggest that he wait outside.
Advice after advise	Use that plus bare verb after advise when giving formal guidance.	The nurse advised that she drink more water.
Urgent request after urge	Use that plus bare verb after urge when asking strongly for action.	They urged that the council act quickly.
Neutral recommendation	Use that plus bare verb after recommend to sound careful and professional.	I recommend that you book early.

The subjunctive often marks a situation that is contrary to fact. For an unreal present, use were or the past simple: If I were rich, I would travel more and If she knew him, she would call. For an unreal past, use had + past participle in the if-clause and would + base verb in the result: If they had left earlier, they would have arrived on time. The choice depends on time. Present unreal situations use past forms to show distance from reality. Past unreal situations use the past perfect because the speaker is talking about an event that did not happen.

Core meanings of subjunctive unreality

Example	Pattern
If I were taller, I could reach the shelf.	Use the subjunctive for situations that are not fact but only imagined or contrary to fact.
I wish it were warmer today.	Use the subjunctive for wishes and regrets about things that are different from reality.
The teacher insisted that the class be quiet.	Use the subjunctive for recommendations and demands when a formal clause follows.
He behaves as if he were a celebrity.	Use the subjunctive for unreal comparisons after phrases like as if and as though.

The pattern had + past participle shows a past situation that was imagined, regretted, or missed. It appears in clauses about things that did not happen: If I had known, I would have called and She wished she had taken the job. In a wish, it can show disappointment about the past: I wish we had stayed longer. In conditional sentences, the same form sets up a result that belongs to an unreal past, which connects directly to Conditional. The form points to a different version of events, not to a completed fact.

I	have	had seen	If I had seen the sign, I would have stopped.
you	have	had finished	If you had finished earlier, we could have gone out.

In everyday speech, many speakers use was where formal English prefers were, especially in unreal clauses: If I was wrong, I’m sorry and I wish she was here. This form is very common in conversation, while were remains the standard formal subjunctive form. The choice depends on style and audience. In careful writing, were signals the unreal meaning more clearly. In casual conversation, was often appears even when the speaker is not describing a fact. When reporting speech or thoughts, these patterns can also carry into Indirect Speech.
