Definition of Adverbial Clauses

An adverbial clause is a group of words that contains a subject and a verb and functions as an adverb. This means it modifies a verb, an adjective, or another adverb within the main clause of a sentence. Adverbial clauses provide information about when, where, why, how, under what condition, or to what extent something happens. They add detail and context, making sentences more informative and engaging.

Unlike independent clauses, which can stand alone as complete sentences, adverbial clauses are dependent clauses. This means they cannot stand alone and must be connected to an independent clause to form a complete sentence. The connection is usually made with a subordinating conjunction, which introduces the adverbial clause and establishes its relationship to the main clause.

Adverbial clauses are extremely versatile. They can appear before or after the main clause.

When the adverbial clause comes before the main clause, it is usually separated by a comma. When it follows the main clause, a comma is generally not needed unless it adds clarity or emphasis.

The choice of subordinating conjunction determines the specific type of relationship the adverbial clause has with the main clause, such as time, place, reason, or condition.

Structural Breakdown of Adverbial Clauses

The basic structure of an adverbial clause is as follows:

Subordinating Conjunction + Subject + Verb (+ Optional Elements)

Let’s break down each component:

• Subordinating Conjunction: This word connects the adverbial clause to the main clause and indicates the relationship between them. Common subordinating conjunctions include because, although, if, when, where, while, since, as, after, before, until, unless, so that, and than.
• Subject: This is the noun or pronoun that performs the action in the adverbial clause.
• Verb: This is the action word or state of being in the adverbial clause. It must agree with the subject in number and tense.
• Optional Elements: These can include objects, complements, adverbs, and other modifiers that add further detail to the adverbial clause.

Here are some examples illustrating this structure:

• Because it was raining, we stayed inside. (Reason)
• If you study hard, you will pass the exam. (Condition)
• When the sun sets, the birds return to their nests. (Time)
• Where there is a will, there is a way. (Place)

The order of the clauses in the sentence can be changed, but the meaning remains the same. However, the punctuation may need to be adjusted.

Adverbial Clause + Comma + Main Clause

or

Main Clause + Adverbial Clause (usually no comma)

For example:

• Because it was raining, we stayed inside.
• We stayed inside because it was raining.

Types of Adverbial Clauses

Adverbial clauses can be classified into several types based on the relationship they express with the main clause. Understanding these different types is crucial for using adverbial clauses correctly and effectively.

Adverbial Clauses of Time

Adverbial clauses of time indicate when an action occurs. They are introduced by subordinating conjunctions such as when, while, as, after, before, since, until, as soon as, whenever, and as long as.

Examples:

• When the bell rings, the students leave the classroom.
• While I was walking to school, I saw an old friend.
• After I finish my work, I will go to the gym.
• Before you leave, please turn off the lights.
• Since I moved to this city, I have been much happier.

Adverbial Clauses of Place

Adverbial clauses of place indicate where an action occurs. They are introduced by subordinating conjunctions such as where and wherever.

Examples:

• Where there is smoke, there is fire.
• Wherever you go, I will follow you.
• You can sit wherever you like.

Adverbial Clauses of Reason

Adverbial clauses of reason explain why an action occurs. They are introduced by subordinating conjunctions such as because, since, as, and inasmuch as.

Examples:

• Because it was raining, we stayed inside.
• Since you are not feeling well, you should stay home.
• As it was getting late, we decided to go home.

Adverbial Clauses of Purpose

Adverbial clauses of purpose explain the intention or goal of an action. They are introduced by subordinating conjunctions such as so that, in order that, and lest.

Examples:

• I study hard so that I can get good grades.
• He exercises regularly in order that he can stay healthy.
• Take an umbrella lest it should rain.

Adverbial Clauses of Result

Adverbial clauses of result indicate the consequence or outcome of an action. They are often introduced by the correlative conjunctions so…that and such…that.

Examples:

• It was so cold that the lake froze.
• She was so tired that she fell asleep immediately.
• It was such a beautiful day that we went for a picnic.

Adverbial Clauses of Condition

Adverbial clauses of condition state the circumstances under which an action will occur. They are introduced by subordinating conjunctions such as if, unless, provided that, as long as, in case, and on condition that.

Examples:

• If it rains, we will stay home.
• Unless you hurry, you will miss the bus.
• Provided that you have a valid ticket, you can enter the concert.
• As long as you promise to be careful, I will lend you my car.

Adverbial Clauses of Concession

Adverbial clauses of concession express a contrast or unexpected circumstance in relation to the main clause. They are introduced by subordinating conjunctions such as although, though, even though, while, whereas, and even if.

Examples:

• Although it was raining, we went for a walk.
• Though he is rich, he is not happy.
• Even though she was tired, she finished her work.
• While I understand your point, I don’t agree with you.

Adverbial Clauses of Manner

Examples:

• He sings as his father does.
• She acted as if she didn’t know me.
• He spoke as though he were an expert.

Adverbial Clauses of Comparison

Adverbial clauses of comparison compare two things or actions. They are introduced by subordinating conjunctions such as than and as.

Examples:

• He is taller than I am.
• She is not as intelligent as her brother.

Usage Rules for Adverbial Clauses

Using adverbial clauses correctly involves understanding a few key rules:

1. Punctuation: As mentioned earlier, use a comma after the adverbial clause when it comes before the main clause. When the adverbial clause follows the main clause, a comma is usually not necessary unless it adds clarity or emphasis.
2. Subordinating Conjunctions: Choose the correct subordinating conjunction to express the intended relationship between the adverbial clause and the main clause. Using the wrong conjunction can change the meaning of the sentence.
3. Verb Tense: Ensure that the verb tenses in the adverbial clause and the main clause are consistent and logical. This is especially important in conditional sentences.
4. Subject-Verb Agreement: The verb in the adverbial clause must agree with its subject in number and person.
5. Avoid Dangling Clauses: Make sure the adverbial clause clearly modifies the intended element in the main clause. A dangling clause doesn’t have a clear connection to the main clause.

Here’s an example of a dangling clause:

• Incorrect: Walking down the street, the buildings looked impressive. (Who was walking?)
• Correct: Walking down the street, I found the buildings looked impressive.

Common Mistakes with Adverbial Clauses

Several common mistakes can occur when using adverbial clauses. Being aware of these errors can help you avoid them in your own writing.

• Incorrect Subordinating Conjunction: Using the wrong conjunction can alter the meaning of the sentence.
• Incorrect: Although it was raining, I stayed inside. (The opposite of what is expected)
• Correct: Because it was raining, I stayed inside.
• Missing Comma: Forgetting the comma when the adverbial clause precedes the main clause.
• Incorrect: When I finish my work I will go home.
• Correct: When I finish my work, I will go home.
• Dangling Modifier: The adverbial clause does not clearly modify anything in the main clause.
• Incorrect: After finishing the homework, the TV was turned on.
• Correct: After finishing the homework, I turned on the TV.
• Incorrect Verb Tense: Using inconsistent verb tenses between the clauses.
• Incorrect: If I will study, I would pass the exam.
• Correct: If I study, I will pass the exam.
• Fragmented Clause: Treating an adverbial clause as a complete sentence.
• Incorrect: Because it was raining.
• Correct: Because it was raining, we stayed inside.

Advanced Topics in Adverbial Clauses

For those seeking a deeper understanding of adverbial clauses, there are several advanced topics to explore:

• Elliptical Adverbial Clauses: These are clauses where some words are omitted because they are understood from the context. For example: “I will arrive as soon as possible” is short for “I will arrive as soon as it is possible.”
• Reduced Adverbial Clauses: These are clauses that have been shortened, often by omitting the subject and auxiliary verb. For example: “While walking in the park, I saw a friend” is a reduction of “While I was walking in the park, I saw a friend.”
• Adverbial Clauses with Verbless Constructions: These clauses do not contain a verb but still function as adverbs. For example: “Although tired, she continued working.”
• The Use of “That” Clauses as Adverbial Modifiers: While “that” clauses are typically used as noun clauses or adjective clauses, they can sometimes function adverbially, especially in expressions of result or purpose.
• The Interplay Between Adverbial Clauses and Other Clause Types: Understanding how adverbial clauses interact with noun clauses, adjective clauses, and other sentence elements can lead to more sophisticated and nuanced writing.
