Definition of Adverbial Clauses

An adverbial clause is a group of words that contains a subject and a verb and functions as an adverb within a sentence. Like adverbs, adverbial clauses modify verbs, adjectives, or other adverbs. They provide additional information about the action, state, or quality described in the main clause. The key characteristic of an adverbial clause is that it begins with a subordinating conjunction, which connects the clause to the main clause. These conjunctions indicate the relationship between the adverbial clause and the main clause, such as time, place, reason, condition, or manner.

Think of an adverbial clause as answering questions like: When? Where?

Why? How?

Under what condition? To what extent?

These clauses add detail and context, making sentences more informative and engaging. Understanding how to use them correctly is crucial for clear and effective communication.

For example, in the sentence “Because it was raining, I took an umbrella,” the clause “because it was raining” is an adverbial clause. It modifies the verb “took” by explaining the reason why the action occurred. Similarly, in “I will call you when I arrive,” the clause “when I arrive” modifies the verb “will call” by specifying the time of the action.

Structural Breakdown

An adverbial clause typically consists of three main components:

1. 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, before, after, until, so that, even though.
2. Subject: The noun or pronoun that performs the action or is in the state described by the verb.
3. Verb: The action word or state-of-being word that describes what the subject does or is.

The basic structure can be represented as: Subordinating Conjunction + Subject + Verb (+ optional elements).

Consider the sentence: “If you study hard, you will succeed.” Here:

• If is the subordinating conjunction.
• You is the subject of the adverbial clause.
• Study is the verb of the adverbial clause.

The order of the clauses can be reversed. When the adverbial clause comes before the main clause, a comma usually separates the two clauses. For example: “Because I was tired, I went to bed early.” (Adverbial clause first, comma used). “I went to bed early because I was tired.” (Main clause first, no comma needed). The comma indicates a slight pause and helps to separate the two distinct parts of the sentence.

Types of Adverbial Clauses

Adverbial clauses can be classified based on the type of information they provide. Here are the main categories:

Time Clauses

Time clauses indicate when an action occurs. They are introduced by subordinating conjunctions such as when, while, as, before, after, since, until, as soon as, whenever.

Example: “I will leave when the meeting ends.“

Place Clauses

Place clauses specify the location where an action takes place. They are introduced by subordinating conjunctions such as where, wherever.

Example: “You can sit wherever you like.“

Manner Clauses

Manner clauses describe how an action is performed. They are typically introduced by as, as if, as though.

Example: “He acted as if he were the boss.“

Reason Clauses

Reason clauses explain why an action occurs. They are introduced by subordinating conjunctions such as because, since, as.

Example: “Because it was raining, I stayed home.“

Purpose Clauses

Purpose clauses indicate the intention behind an action. They are introduced by subordinating conjunctions such as so that, in order that, that.

Example: “I study hard so that I can get good grades.“

Result Clauses

Result clauses show the consequence of an action. They are often introduced by so…that, such…that.

Example: “It was so cold that the lake froze.“

Condition Clauses

Condition clauses state the conditions under which an action will occur. They are typically introduced by if, unless, provided that, as long as, in case.

Example: “If it rains, we will stay inside.“

Concession Clauses

Concession clauses express a contrast or unexpected circumstance. They are introduced by subordinating conjunctions such as although, though, even though, while, whereas.

Example: “Although it was difficult, I finished the task.“

Comparison Clauses

Comparison clauses make comparisons between two things. They are often introduced by than, as…as.

Example: “He is taller than I am.“

Usage Rules for Adverbial Clauses

Using adverbial clauses correctly involves understanding a few key rules:

• Placement: Adverbial clauses can come before or after the main clause. If the adverbial clause comes first, use a comma to separate it from the main clause. If it comes after, a comma is usually not needed.
• Tense Agreement: Ensure that the tense in the adverbial clause agrees logically with the tense in the main clause. For example, “I will call you when I arrive” (future tense in both clauses).
• Subjunctive Mood: In conditional sentences, use the subjunctive mood in the if clause to express hypothetical or unreal situations. For example, “If I were you, I would accept the offer.”
• “That” Clauses: When using “so that” or “in order that” to introduce purpose clauses, ensure the main clause expresses an intention or action that facilitates the purpose. For example, “I study hard so that I can get good grades.”
• Avoiding Ambiguity: Ensure the meaning of the adverbial clause is clear and unambiguous. Avoid placing the clause in a position that could create confusion about which word or phrase it modifies.

Understanding these rules will help you use adverbial clauses effectively and avoid common errors. Pay attention to the placement, tense agreement, and the appropriate use of conjunctions to ensure clarity and accuracy in your writing and speaking.

Common Mistakes with Adverbial Clauses

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

• Incorrect Comma Usage: Forgetting the comma when the adverbial clause comes first, or using a comma when it’s not needed.
  • Incorrect: Because it was raining I stayed home.
  • Correct: Because it was raining, I stayed home.
• Misusing Subordinating Conjunctions: Using the wrong conjunction to express the intended relationship between clauses.
  • Incorrect: Despite it was raining, I took an umbrella. (Should be “Because”)
  • Correct: Because it was raining, I took an umbrella.
• Tense Disagreement: Using inconsistent tenses between the main clause and the adverbial clause.
  • Incorrect: I will call you when I arrived.
  • Correct: I will call you when I arrive.
• Fragmented Clauses: Using an incomplete clause that lacks a subject or verb.
  • Incorrect: Because raining. I stayed home.
  • Correct: Because it was raining, I stayed home.

By being aware of these common mistakes, you can improve the accuracy and clarity of your sentences. Always double-check your work to ensure correct comma usage, appropriate conjunctions, consistent tenses, and complete clauses.

Advanced Topics

For advanced learners, consider these more complex aspects of adverbial clauses:

• Elliptical Clauses: These are clauses where some words are omitted because they are understood from the context. For example, “While (I was) walking, I saw a friend.”
• Reduced Adverbial Clauses: These are clauses shortened to participial phrases for conciseness. For example, “Because he was tired, he went to bed” can be reduced to “Being tired, he went to bed.”
• Embedded Clauses: These are clauses within clauses, adding layers of complexity. For example, “I know that because he told me, I should trust him.”
• Nominal Relative Clauses as Adverbial Clauses: Clauses beginning with “what” or “whatever” can sometimes function as adverbial clauses, typically expressing a condition or concession. For example, “Whatever happens, I will be there for you.“

Exploring these advanced topics will further enhance your understanding and mastery of adverbial clauses, enabling you to use them with greater sophistication and precision.
