What Is the Subjunctive Mood?
The subjunctive mood expresses, hypothetical situations, wishes, doubts, or conditions contrary to fact. In adverbial clauses, it often appears after certain conjunctions that introduce purpose, condition, or time.
What Are Adverbial Clauses?
Adverbial clauses function as adverbs, modifying the verb in the main clause. They answer questions like when, why, how, and under what conditions. When these clauses express uncertainty, purpose, or hypothetical conditions, the subjunctive mood is often required.
When to Use the Subjunctive in Adverbial Clauses
The subjunctive mood typically appears after specific conjunctions in adverbial clauses, including:
- Purpose: so that, in order that
- Condition: unless, provided that, in case
- Time (when uncertainty exists): before, until, as soon as
- Concession: although, even if, whether or not
Example: She studies hard so that she may pass the exam. (Subjunctive: may pass)
Example: I’ll wait until he arrive. (Subjunctive: arrive, not arrives, when uncertainty is implied.)
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: She speaks quietly so that he hears her. (Indicative used instead of subjunctive)
Correct: She speaks quietly so that he hear her. (Subjunctive: hear)
Similarly:
Incorrect: I’ll call you before he leaves. (Indicative shows certainty)
Correct: I’ll call you before he leave. (Subjunctive: leave, showing 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 will explain it so that he understands.
Correct: I will explain it so that he understand. (Subjunctive: understand)
Ignoring Uncertainty:
Incorrect: She’ll wait until he arrives. (Indicative implies certainty)
Correct: She’ll wait until he arrive. (Subjunctive: arrive, indicating uncertainty.)
Forgetting Condition Clauses:
Incorrect: Unless he agrees, we cannot proceed. (Indicative used)
Correct: Unless he agree, we cannot proceed. (Subjunctive: agree)
Practical Tips for Success
To master the subjunctive in adverbial clauses, follow these strategies:
Learn Key Conjunctions: Focus on conjunctions that trigger the subjunctive, like so that, unless, before, and provided that.
Look for Uncertainty: Use the subjunctive when the action is uncertain, hypothetical, or dependent on another event.
Check the Verb Form: In the subjunctive mood, the base form of the verb is used without -s for third-person singular.
Practice with Sentences: Write complex sentences using subjunctive-triggering conjunctions to reinforce understanding.

Subjunctive In Adverbial Clauses – FAQ
The subjunctive mood is a grammatical feature used to express wishes, doubts, or hypothetical situations. Unlike the indicative mood, which states facts, the subjunctive often conveys what could be, should be, or might be.
Subjunctive in adverbial clauses is used when expressing conditions, purpose, or time that are hypothetical or uncertain. For instance, in clauses beginning with if, unless, or in case, the subjunctive may appear if the situation described is not yet realized or is purely speculative.
