The Subjunctive Mood
it is essential that, if I were
What is the Subjunctive?
The subjunctive shows attitude or mood rather than time. It expresses wishes, necessity, demands, suggestions, or imaginary situations. It is common in formal writing, academic contexts, and polite English.
It is essential that every student be present. / If I were you, I'd take the job.
Present Subjunctive — Formal Requirements
Use the base form (no -s, no -to) after verbs and expressions of importance, necessity, or suggestion.
- ⚠ No -s for third person: It is essential that he be (NOT "is" or "bes").
- ⚠ No "to": The doctor recommended that she rest (NOT "to rest").
- 💡 In British English, "should + base verb" is also accepted: It is vital that every student should attend.
| Trigger | Example |
|---|---|
| suggest / recommend | The teacher suggested that we study harder. |
| demand / insist / require | They demanded that she apologise. |
| It is essential / important / vital / necessary that... | It is essential that every student be here. |
| It is recommended / requested that... | It is requested that phones be switched off. |
Past Subjunctive — Unreal Situations
Use were (for all subjects) after if, wish, and as if/as though to describe imaginary or contrary-to-fact situations.
- ✅ Formal/standard: If she were here...
- ⚠ Informal only: If she was here... (acceptable in speech but not formal writing)
| Context | Example |
|---|---|
| If-clause (unreal) | If I were you, I'd talk to him. |
| Wish | I wish it were summer all year. |
| As if / as though | He talks as if he were the boss. |
"It's Time / About Time / High Time"
Use Past Simple after these expressions — the form looks past but refers to the present or near future. It expresses mild criticism or urgency.
- It's time you went to bed.
- It's high time we left.
- It's about time she got a new job.
