Definition of Adverbial Clauses

An adverbial clause is a group of words that contains a subject and a verb and functions as an adverb. Like adverbs, adverbial clauses modify verbs, adjectives, or other adverbs within the main clause of a sentence. They provide information about when, where, why, how, under what condition, or to what extent the action or state described in the main clause occurs. Adverbial clauses are dependent clauses, meaning they cannot stand alone as complete sentences. They are always introduced by a subordinating conjunction, which connects the clause to the main clause and indicates the relationship between the two.

Adverbial clauses add detail and nuance to sentences, making them more informative and descriptive. They allow writers and speakers to express complex relationships between ideas and events. For example, instead of simply saying “I was late,” you could use an adverbial clause to explain why: “I was late because the traffic was terrible.” This provides additional context and makes the sentence more meaningful.

The function of an adverbial clause is to modify some element of the main clause, answering questions such as:

  • When? (time)
  • Where? (place)
  • Why? (reason)
  • How? (manner)
  • For what purpose? (purpose)
  • With what result? (result)
  • Under what condition? (condition)
  • Despite what? (concession)
  • To what extent? (degree/comparison)

Structural Breakdown

The basic structure of an adverbial clause consists of three main components:

  1. Subordinating Conjunction: This word introduces the adverbial clause and connects it to the main clause. Common subordinating conjunctions include because, although, if, when, where, while, since, as, before, after, until, unless, so that, and than.
  2. Subject: This is the noun or pronoun that performs the action or is in the state described by the verb in the adverbial clause.
  3. Verb: This is the action word or state-of-being word in the adverbial clause. It indicates what the subject is doing or being.

Therefore, the general formula for an adverbial clause is:

Subordinating Conjunction + Subject + Verb (+ optional additional elements)

Here are some examples illustrating this structure:

  • Because it was raining, we stayed inside. (Subordinating conjunction + Subject + Verb)
  • If you study hard, you will pass the exam. (Subordinating conjunction + Subject + Verb)
  • When the sun sets, the birds return to their nests. (Subordinating conjunction + Subject + Verb)

An adverbial clause can appear either before or after the main clause. When it appears before the main clause, it is usually followed by a comma.

When it appears after the main clause, a comma is generally not needed (unless it is a nonrestrictive clause providing extra, non-essential information).

Example:

  • Before I leave, I need to finish this report. (Adverbial clause before main clause, comma used)
  • I need to finish this report before I leave. (Adverbial clause after main clause, no comma needed)

Types of Adverbial Clauses

Adverbial clauses can be classified into different types based on the kind of information they provide. The most common types are:

Adverbial Clauses of Time

Usage Rules

Using adverbial clauses correctly involves understanding several key rules:

  1. Correct Subordinating Conjunction: Choose the appropriate subordinating conjunction to accurately convey the intended meaning (time, reason, condition, etc.).
  2. Subject-Verb Agreement: Ensure that the subject and verb within the adverbial clause agree in number (singular or plural).
  3. Tense Consistency: Maintain consistent verb tenses between the main clause and the adverbial clause, unless there is a logical reason to change tenses.
  4. Punctuation: Use a comma after the adverbial clause when it precedes the main clause. When the adverbial clause follows the main clause, a comma is usually not needed (unless it is a nonrestrictive clause).
  5. Avoid Misplaced Modifiers: Ensure that the adverbial clause is placed close enough to the element it modifies to avoid ambiguity.

Examples illustrating these rules:

  • Correct: Because it was raining, we stayed inside. (Correct subordinating conjunction and punctuation)
  • Incorrect: Because raining, we stayed inside. (Missing subject and incorrect conjunction usage)
  • Correct: If he studies hard, he will pass the exam. (Tense consistency)
  • Incorrect: If he studies hard, he passed the exam. (Incorrect tense)

Common Mistakes

Here are some common mistakes to avoid when using adverbial clauses:

  • Using a coordinating conjunction instead of a subordinating conjunction: Coordinating conjunctions (and, but, or, nor, for, so, yet) cannot introduce adverbial clauses.
  • Missing subject or verb in the adverbial clause: An adverbial clause must have both a subject and a verb.
  • Incorrect verb tense in the adverbial clause: Ensure that the verb tense in the adverbial clause is appropriate for the context.
  • Misplacing the adverbial clause: Place the adverbial clause close to the element it modifies to avoid confusion.
  • Incorrect punctuation: Remember to use a comma when the adverbial clause comes before the main clause.

Examples of Correct vs. Incorrect Usage:

Incorrect Correct Explanation
I was tired, so I went to bed. Because I was tired, I went to bed. Coordinating conjunction “so” incorrectly used.
Because raining, we stayed home. Because it was raining, we stayed home. Missing subject in the adverbial clause.
If he will study, he will pass. If he studies, he will pass. Incorrect tense in the adverbial clause.
She ate dinner quickly because she was late. Because she was late, she ate dinner quickly. While grammatically correct, moving the clause improves clarity.
When I arrived I called her. When I arrived, I called her. Missing comma after the adverbial clause when it comes first.

Advanced Topics

For advanced learners, here are some more complex aspects of adverbial clauses:

  • Elliptical Adverbial Clauses: These are clauses where some words are omitted because they are understood from the context. For example: “While (I

    am) in Paris, I visited many museums.”

  • Adverbial Clauses with Reduced Verb Phrases: In some cases, the verb phrase in an adverbial clause can be reduced to a participle. For example: “Having finished his work, he went home.”
  • The Subjunctive Mood in Adverbial Clauses: The subjunctive mood is sometimes used in adverbial clauses of condition or purpose to express hypothetical or desired situations. For example: “He insisted that everyone be on time so that the meeting would start promptly.”

FAQ

What is the difference between an adverbial clause and an adverbial phrase?

An adverbial clause contains a subject and a verb, while an adverbial phrase does not. For example: “Because it was raining” (clause) vs. “Due to the rain” (phrase).

Can an adverbial clause modify a noun?

No, adverbial clauses modify verbs, adjectives, or other adverbs. To modify a noun, you would use an adjective clause.

Is it always necessary to use a comma with an adverbial clause?

No, a comma is generally used when the adverbial clause comes before the main clause. When it follows the main clause, a comma is usually not needed unless the clause is nonrestrictive (provides extra, non-essential information).

What are correlative conjunctions, and how are they used in adverbial clauses?

Correlative conjunctions (such as so…that and such…that) are used to connect two related ideas in a sentence. In adverbial clauses, they often indicate a cause-and-effect relationship or a result. For example: “It was so cold that the lake froze.”

Can an adverbial clause be embedded within another clause?

While less common, it is possible for an adverbial clause to be embedded within another clause, although this can sometimes make the sentence complex and harder to read. Clarity should always be the primary goal.

Conclusion

Adverbial clauses are powerful tools for enhancing the clarity, detail, and complexity of your writing and speaking. By understanding their structure, types, and usage rules, you can effectively incorporate them into your communication to express a wide range of relationships between ideas and events.

Whether you are explaining the reason for an action, specifying when or where something happened, or expressing a condition or concession, adverbial clauses allow you to convey your message with precision and nuance. Continue to practice and explore the various ways adverbial clauses can be used, and you will undoubtedly see a significant improvement in your English language skills.
