C1 Lesson 3: The Subjunctive Mood
Why It Matters: Formal & Hypothetical Language
The subjunctive mood is not a tense; it's a special verb form used for ideas that are not facts. Mastering it is essential for sophisticated and formal communication.
The manager insists that every employee arrives on time.
The manager insists that every employee arrive on time.
The Three Forms of the Subjunctive Mood 📖
1. The Present Subjunctive
Use: For formal demands, proposals, and recommendations after verbs (suggest, insist, demand) and adjectives (it is vital, essential, imperative).
Rule: The verb in the subjunctive clause is always in its base form (no -s, -ed, etc.).
- "The university requires that all students pass an English test." (not 'passes')
- "It is imperative that the historic buildings be protected." (the passive subjunctive)
2. The Past Subjunctive
Use: For unreal or hypothetical situations in the present (e.g., present wishes, Second Conditional).
Rule: Use the Past Simple verb form. For the verb 'to be', 'were' is traditionally used for all subjects.
- Present Wish: I don't have enough time. I wish I had more time.
- Hypothetical Advice: If I were you, I would accept the job offer.
3. The Past Perfect Subjunctive
Use: For unreal or hypothetical situations in the past (e.g., past regrets, Third Conditional).
Rule: Use the Past Perfect verb form (had + past participle).
- Past Regret: I didn't go to the party. I wish I had gone.
- Past Hypothesis: If she had studied harder, she would have passed the exam.
