In English, we have three main moods in grammar: the indicative (which deals with facts or reality), the subjunctive (used for hypothetical situations), and the imperative. The subjunctive mood is used to express hypothetical situations, wishes, suggestions, or desires.
The subjunctive mood is a way of expressing hypothetical situations, desires, wishes, doubts, or possibilities in language. It’s commonly used when talking about things that may not be true or certain.
For example
I wish I were taller.
If I were rich, I would travel the world.
She must be here on time.
Forms of Subjunctive Mood
Basic Structure
Base Form of Verb: The subjunctive mood often involves using a base form of the verb, which is different from the indicative mood.
It typically does not include adding an “-s” or “-es” to the verb for third person singular subjects.
- It’s crucial that he arrive on time.
- She recommended that he study harder.
Present Subjunctive
Base Form of Verb: Use the base form of the verb (without “-s” or “-es”).
- It’s essential that she be here on time.
- They demanded that he pay immediately.
Past Subjunctive
Past Tense Form of Verb: Use the past tense form of the verb (without adding “-ed” for regular verbs).
- If I were rich, I would travel the world.
- I wish he were here with us.
Conditional Clauses
Use of “If”: Used to express hypothetical conditions.
- If it were sunny, we would go for a picnic.
- If she were taller, she could reach the top shelf.
Wishes and Desires
Introductory Verbs: Often introduced by verbs like wish, desire, or hope.
- I wish she were more understanding.
- They hope he be successful in his endeavors.
Modal Verbs
Must, Should, Would: Used to express necessity, obligation, or preference.
- She must be here on time.
- It’s essential that he should arrive early.
Imperative Mood
Implied Subjunctive: In commands or requests, the subjunctive mood is often implied.
- Let him be happy.
- I suggest you go now.
Verb Agreement
Consistency: Subjunctive verbs may not agree with the subject in the same way as indicative verbs.
Usage
Hypothetical Situations: The subjunctive mood is used for hypothetical situations, wishes, desires, and polite requests.
Examples of subjunctive mood

Hypothetical situations
Expressing doubts or uncertainty
- I’m uncertain whether they attend the meeting.
- I doubt that it rain tomorrow.
- I’m unsure if they arrive before noon.
- It’s unlikely that he complete the task by himself.
- I’m hesitant about whether they approve the proposal.
- I’m not entirely sure if it be the right decision.
- It’s doubtful that she be available for the appointment.
Subjunctive Mood: Backshift
When using the subjunctive mood, verbs often change form. This process is commonly referred to as ‘backshift‘. Here are the changes:
- Am/Is/Are → Be
- Original: You are confident.
- Subjunctive: I suggest that you be confident.
- As you can see, ‘are‘ in the declarative mood is changed to ‘be‘ in the subjunctive mood.
- Is → Be
- Original: The rule is clear.
- Subjunctive: It is essential that the rule be clear.
- The verb “is” in the declarative mood is changed to “be” in the subjunctive mood to express necessity or importance.
- Has → Have
- Original: She has an English degree.
- Subjunctive: I suggest she have an English degree.
- ‘Has‘ in the declarative mood is changed to ‘have‘ in the subjunctive mood.
- Was → Were
- Original: I was happy.
- Subjunctive: I wish I were happy.
- ‘Was‘ in the declarative mood is changed to ‘were‘ in the subjunctive mood.
- Verbs in the 3rd person singular → The ‘-s’ is omitted
- Original: He exercises every day.
- Subjunctive: I suggest he exercise every day.
- Here, the ‘-s’ in the 3rd person singular verb ‘exercises‘ is omitted when it’s used in the subjunctive mood.
