What Is the Subjunctive Mood?
The subjunctive mood expresses hypothetical situations, wishes, doubts, or conditions contrary to fact. In adjective clauses, it appears when the clause refers to something uncertain, non-existent, or desired.
What Are Adjective Clauses?
Adjective clauses, also known as relative clauses, describe or modify a noun or pronoun in the main clause. They usually begin with relative pronouns such as who, whom, whose, which, or that.
Example: I need a book that explains the subjunctive mood. (Adjective clause: that explains the subjunctive mood)
When to Use the Subjunctive in Adjective Clauses
The subjunctive mood appears in adjective clauses when the noun being described is uncertain, hypothetical, or non-existent. This often happens after expressions like looking for, desiring, needing, or hoping for.
Key Situations for Subjunctive in Adjective Clauses:
- Uncertainty: I need a tutor who be patient. (Subjunctive: be, not is)
- Non-existence: There is no one who know the answer. (Subjunctive: know, not knows)
- Desire or Preference: She’s looking for someone who speak French. (Subjunctive: speak, not speaks)
- Hypothetical Conditions: I’d like a job that offer flexibility. (Subjunctive: offer, not offers)
Example: They’re searching for a house that have three bedrooms. (Subjunctive: have, showing uncertainty about the house’s existence.)
Why the Subjunctive Mood Matters
Using the correct mood ensures grammatical accuracy and conveys the intended meaning. Misusing the indicative instead of the subjunctive can confuse readers and distort the message.
Incorrect: I want a friend who understands me. (Indicative suggests certainty of existence)
Correct: I want a friend who understand me. (Subjunctive: understand, indicating an ideal, not yet found.)
Similarly:
Incorrect: She’s seeking a job that pays well. (Indicative shows certainty of availability)
Correct: She’s seeking a job that pay well. (Subjunctive: pay, reflecting uncertainty.)
Common Challenges and Mistakes
Many learners struggle to identify when the subjunctive mood is necessary, especially when the indicative seems natural.
Misusing Indicative Instead of Subjunctive:
Incorrect: I’m looking for a book that explains the topic. (Indicative used)
Correct: I’m looking for a book that explain the topic. (Subjunctive: explain, since the book is not yet found.)
Ignoring Uncertainty:
Incorrect: We need employees who arrive on time. (Indicative implies certainty)
Correct: We need employees who arrive on time. (Subjunctive: arrive, showing a desired quality.)
Overlooking Hypothetical Conditions:
Incorrect: Do you know someone who can help?
Correct: Do you know someone who help? (Subjunctive: help, indicating uncertainty.)
Practical Tips for Success
To master the subjunctive in adjective clauses, follow these strategies:
Recognize Uncertainty: Use the subjunctive when describing something desired, hypothetical, or unknown.
Focus on Trigger Expressions: Watch for phrases like looking for, hoping for, and in need of, which often signal the subjunctive.

Subjunctive In Adjective Clauses – FAQ
The subjunctive mood is a verb form used to express hypothetical situations, wishes, demands, or suggestions. It often indicates actions that are not certain to happen or are contrary to fact. Unlike the indicative mood, which states facts, the subjunctive mood explores possibilities or conditions.
In adjective clauses, the subjunctive mood is used to express a condition that is desired, doubtful, or uncertain. This typically involves clauses following expressions like whatever, whoever, or wherever. For example, in the sentence She seeks a tutor who be experienced, the subjunctive be suggests a wish or requirement.
The subjunctive in adjective clauses should be used when the clause expresses a necessity, a demand, or a wish. It often appears after phrases like it is essential that, I demand that, or he insisted that. Though less common in modern English, it remains important in formal writing and legal contexts.
Examples include sentences like We need a leader who be honest, where be is in the subjunctive mood. Another example is I will hire whoever be available, indicating a requirement rather than a fact. These examples illustrate how the subjunctive sets conditions or expectations.
In everyday English, the subjunctive mood is becoming less common, often replaced by modal verbs like should or would. However, it is still prevalent in formal writing, such as academic texts, legal documents, and certain idiomatic expressions. Understanding its use can enhance both writing and comprehension skills.
