I. Introduction
The subjunctive mood is a grammatical mood that expresses various states such as wishes, suggestions, commands, or conditions that are contrary to fact. It allows speakers and writers to convey ideas that are not based on objective reality or certainty. Understanding the subjunctive mood is essential for mastering the nuances of the English language and expressing complex thoughts accurately.
II. Forms of the Subjunctive Mood
A. Present Subjunctive
In the present subjunctive, the base form of the verb (the infinitive without “to”) is used. This form is commonly used in certain types of clauses, especially after certain verbs and expressions that express a desire, demand, recommendation, or necessity.
- After certain verbs: Verbs like “suggest,” “recommend,” “demand,” “request,” “insist,” “require,” etc. are often followed by a clause in the present subjunctive.
- Example: The teacher recommended that he study harder. (Here, “study” is in the present subjunctive. The subject “he” is followed by the base form of the verb.)
- Example: She insisted that they be on time. (In this case, “be” is the present subjunctive form.)
- In formal expressions: Some formal expressions also use the present subjunctive. For example, “It is important/necessary/essential that…”
- Example: It is essential that everyone attend the meeting.
B. Past Subjunctive
The past subjunctive is used to express situations that are contrary to the present fact or to talk about hypothetical or unreal conditions. In most cases, the past subjunctive form of a verb is the same as the simple past tense form of regular verbs. However, the verb “be” is an exception; the past subjunctive form of “be” is “were” for all persons.
- Contrary-to-fact conditions in the present: When we want to talk about a situation that is not true in the present, we use the past subjunctive in the “if” clause and the conditional mood (would + base form) in the main clause.
- Example: If I were rich, I would travel around the world. (The situation of being rich is contrary to the present fact, so “were” is used instead of “was.”)
- Wishes about the present: We can also use the past subjunctive to express wishes about the present.
- Example: I wish I were taller.
C. Past Perfect Subjunctive
The past perfect subjunctive is used to express situations that are contrary to past facts or to talk about unreal past conditions. It is formed by using “had + past participle.”
- Contrary-to-fact conditions in the past: When dealing with a hypothetical situation in the past, the “if” clause uses the past perfect subjunctive and the main clause uses “would have + past participle.”
- Example: If she had studied harder, she would have passed the exam. (She didn’t study harder, and she didn’t pass the exam. This is a contrary-to-fact situation in the past.)
- Regrets about the past: We can use the past perfect subjunctive to express regrets about things that didn’t happen in the past.
- Example: I wish I had taken that job offer.
III. Uses of the Subjunctive Mood
A. Expressing Wishes
The subjunctive mood is commonly used to express wishes. We can use different forms depending on whether the wish is about the present or the past.
- Wishes about the present: As mentioned earlier, we use the past subjunctive for wishes about the present.
- Example: She wishes she were more confident.
- Wishes about the past: For wishes about the past, we use the past perfect subjunctive.
- Example: He wishes he had saved more money when he was young.
B. Making Suggestions and Recommendations
The present subjunctive is often used after verbs that express suggestions or recommendations.
- Example: The doctor suggested that he take more exercise.
- Example: The committee recommended that the project be postponed.
C. Expressing Demands and Requirements
When we want to express a demand or requirement, we can use the present subjunctive.
- Example: The manager demanded that the report be completed by Friday.
- Example: The school requires that students wear uniforms.
D. Hypothetical and Unreal Conditions
The subjunctive mood is crucial for expressing hypothetical or unreal conditions. These are situations that are not likely to happen or are contrary to the facts.
- First Conditional (Real Possibility): This is used to talk about a possible future situation and its likely result. The “if” clause uses the present simple tense, and the main clause uses “will + base form.”
- Example: If it rains tomorrow, I will stay at home.
- Second Conditional (Unreal Present or Future): This is used to talk about an unreal or unlikely situation in the present or future. The “if” clause uses the past subjunctive, and the main clause uses “would + base form.”
- Example: If I won the lottery, I would buy a big house.
- Third Conditional (Unreal Past): This is used to talk about an unreal situation in the past and its imagined result. The “if” clause uses the past perfect subjunctive, and the main clause uses “would have + past participle.”
- Example: If he had caught the train, he would have arrived on time.
IV. Exceptions and Special Cases
A. The Verb “Be”
As mentioned earlier, the verb “be” has an irregular form in the subjunctive mood. In the past subjunctive, “were” is used for all persons instead of “was.”
- Example: If I were you, I would apologize.
B. Informal Usage
In informal English, the subjunctive mood is sometimes not used, especially in spoken language. Instead, the indicative mood may be used.
- Example: I wish he was here. (Informal; the more formal and grammatically correct form would be “I wish he were here.”)
C. Fixed Expressions
There are some fixed expressions in English that use the subjunctive mood. For example, “Long live the king!” and “Heaven forbid!”
V. Tips for Using the Subjunctive Mood Correctly
A. Learn the Trigger Words
Familiarize yourself with the verbs and expressions that typically require the subjunctive mood, such as “suggest,” “recommend,” “demand,” “wish,” etc. This will help you recognize when to use the subjunctive.
B. Practice with Examples

C. Pay Attention to Verb Forms
Make sure you use the correct verb forms for the different types of subjunctive (present, past, past perfect). Pay special attention to irregular verbs and the form of “be.”
