Understanding sentence structure is fundamental to effective communication. Within this structure, clauses play a vital role, acting as the building blocks of complex thoughts. Among these, subordinate clauses deserve special attention for their ability to add nuance and detail.
This guide aims to demystify subordinate clauses, offering clear explanations and practical examples. We will explore their types, functions, and how to integrate them seamlessly into your writing. Mastering these elements will undoubtedly elevate your prose, making your ideas clearer and more compelling for your readers.
The Essence of Subordinate Clauses
A clause is a group of words containing a subject and a verb. Independent clauses, also known as main clauses, can stand alone as a complete sentence because they express a complete thought. Subordinate clauses, in contrast, cannot stand alone; they depend on an independent clause to make sense.
These dependent clauses, as they are also known, add crucial information to the main part of the sentence. They function like adjectives or adverbs, modifying other parts of the sentence and enriching its meaning. Without them, sentences might be simpler but would lack the depth and complexity needed to convey sophisticated ideas.
Think of a subordinate clause as a supporting actor in a play. It has its own lines (subject and verb) but needs the main character (the independent clause) to be part of a complete story. Its presence provides context, explanation, or additional description that is essential for full comprehension.
Identifying Subordinate Clauses: The Role of Subordinating Conjunctions and Relative Pronouns
The key to identifying subordinate clauses often lies in recognizing specific introductory words. Subordinating conjunctions are the most common signal, introducing adverbial clauses and linking them to the main clause. Examples include words like ‘because,’ ‘although,’ ‘since,’ ‘if,’ ‘when,’ ‘while,’ and ‘unless.’
For instance, in the sentence “She succeeded because she worked diligently,” the phrase “because she worked diligently” is a subordinate clause. The subordinating conjunction ‘because’ clearly marks it as dependent, and it explains the reason for her success.
Relative pronouns also introduce subordinate clauses, specifically adjective clauses. These pronouns include ‘who,’ ‘whom,’ ‘whose,’ ‘which,’ and ‘that.’ They refer back to a noun or pronoun in the independent clause, providing more information about it.
Consider the sentence, “The book that I borrowed is overdue.” Here, “that I borrowed” is a subordinate clause introduced by the relative pronoun ‘that.’ It modifies the noun ‘book,’ telling us which specific book is overdue.
Sometimes, subordinate clauses can begin with relative adverbs like ‘where,’ ‘when,’ or ‘why.’ These function similarly to relative pronouns in introducing adjective clauses. “This is the house where I grew up” uses ‘where’ to introduce a clause that describes the house.
The presence of these specific words is a strong indicator. However, it’s crucial to remember that the clause must also contain a subject and a verb to be considered a clause, rather than just a phrase.
Types of Subordinate Clauses and Their Functions
Subordinate clauses primarily fall into three categories based on their function within the sentence: adverbial clauses, adjectival clauses, and noun clauses.
Adverbial Clauses
Adverbial clauses function like adverbs, modifying verbs, adjectives, or other adverbs. They answer questions such as ‘when?’, ‘where?’, ‘why?’, ‘how?’, ‘to what extent?’, or ‘under what condition?’ Subordinating conjunctions typically introduce these clauses.
For example, “When the rain stopped, we went outside.” The clause “When the rain stopped” is an adverbial clause telling us *when* we went outside. It modifies the verb ‘went.’
Another example: “He studies hard so that he can pass the exam.” The clause “so that he can pass the exam” is an adverbial clause explaining *why* he studies hard. It modifies the verb ‘studies.’
Adverbial clauses can appear at the beginning or end of a sentence. When they begin a sentence, they are usually followed by a comma. “Although it was late, she continued to work.” Here, “Although it was late” is an adverbial clause of concession.
The placement can affect emphasis. Placing the adverbial clause at the beginning often highlights the condition or circumstance. Conversely, placing it at the end can integrate it more smoothly into the main statement.
Understanding the different types of relationships adverbial clauses express—time, cause, effect, condition, concession, purpose, manner—is key to using them effectively. Each relationship relies on a specific subordinating conjunction or phrase.
Adjectival Clauses (Relative Clauses)
Adjectival clauses, also known as relative clauses, function like adjectives, modifying nouns or pronouns. They typically begin with a relative pronoun (‘who,’ ‘whom,’ ‘whose,’ ‘which,’ ‘that’) or a relative adverb (‘where,’ ‘when,’ ‘why’).
In the sentence “The person who called left a message,” the clause “who called” is an adjectival clause. It modifies the noun ‘person,’ specifying which person. The relative pronoun ‘who’ connects it to the noun.
These clauses provide descriptive details. “The car, which was red, sped away.” The clause “which was red” describes the car. Notice the use of commas here, indicating a non-restrictive clause.
Restrictive adjectival clauses are essential to the meaning of the sentence and are not set off by commas. “The car that sped away was red.” Here, “that sped away” is restrictive; it identifies which car is being discussed.
The choice between ‘who’ and ‘whom’ depends on the grammatical role of the pronoun within the subordinate clause. ‘Who’ is used as the subject, while ‘whom’ is used as the object. “The student who won the award is here” versus “The student whom we congratulated is here.”
Relative adverbs can also introduce these clauses. “I remember the day when we first met.” The clause “when we first met” modifies ‘day.’ It specifies the particular day being remembered.
Adjectival clauses add specificity and detail, making your descriptions more vivid and precise. They allow you to combine related information efficiently without creating choppy sentences.
Noun Clauses
Noun clauses function as nouns within a sentence. They can act as the subject, object, or complement. These clauses often begin with words like ‘that,’ ‘what,’ ‘whatever,’ ‘who,’ ‘whoever,’ ‘whom,’ ‘whomever,’ ‘when,’ ‘where,’ ‘whether,’ or ‘why.’
Consider the sentence “I know that you are capable.” The clause “that you are capable” is a noun clause serving as the direct object of the verb ‘know.’ It answers the question ‘know what?’
Noun clauses can also be the subject of a sentence. “What you said surprised me.” The entire phrase “What you said” acts as the subject of the verb ‘surprised.’
They can also function as predicate nominatives, renaming the subject. “The problem is that we lack resources.” Here, “that we lack resources” renames ‘problem.’
Unlike adjectival clauses, noun clauses are generally not introduced by relative pronouns that refer to a specific antecedent. The introductory word (‘what,’ ‘who,’ etc.) is part of the clause itself and does not point back to a noun in the main clause.
Determining the function of a noun clause involves identifying its role in the sentence. Is it performing the action, receiving the action, or renaming something? This analysis is key to understanding its grammatical purpose.
Integrating Subordinate Clauses for Enhanced Writing
The skillful use of subordinate clauses can transform simple sentences into sophisticated expressions of thought. They allow for greater detail, nuance, and flow, preventing your writing from becoming monotonous.
One primary benefit is the ability to combine related ideas efficiently. Instead of two short sentences, you can often create one more complex and informative sentence. “The dog barked. It was scared.” can become “The dog barked because it was scared.”
Subordinate clauses also help establish clear relationships between ideas. Using conjunctions like ‘because,’ ‘although,’ or ‘if’ explicitly signals the connection between the main idea and the supporting detail. This guides the reader’s understanding.
Varying sentence structure is crucial for engaging readers. Overreliance on simple sentences can make writing feel childlike. Subordinate clauses provide a natural way to introduce complexity and sophistication.
Adverbial clauses can be used to set the context or provide background information. Placing them at the beginning of a sentence can create anticipation or establish a specific setting before delivering the main point.
Adjectival clauses are excellent for adding descriptive details without interrupting the flow of the main idea. They allow you to pack more information into a single sentence, making your writing more concise.
Noun clauses enable you to express complex thoughts and concepts as single units within a sentence. They are essential for reporting speech, expressing opinions, or stating facts indirectly.
Common Pitfalls and How to Avoid Them
Despite their benefits, subordinate clauses can sometimes lead to grammatical errors if not used carefully. One common issue is the creation of a sentence fragment, where a subordinate clause is presented as a complete sentence.
For example, writing “Because I was tired.” as a standalone sentence is incorrect. It’s a subordinate clause and needs to be attached to an independent clause to form a complete thought, such as “Because I was tired, I went to bed early.”
Another pitfall is ambiguity, particularly with adjectival clauses. If a relative pronoun could refer to more than one noun, the meaning becomes unclear. Ensure the antecedent (the noun being modified) is obvious.
Misplaced modifiers are also a concern. When an adverbial clause or adjectival clause is placed too far from the word it modifies, it can create confusion or an unintended meaning. Always check that your subordinate clause is positioned logically.
Overuse of complex sentence structures can also be detrimental. While subordinate clauses add sophistication, too many can make sentences convoluted and difficult to follow. Strive for clarity and conciseness.
Incorrect punctuation is another common error. Remember to use commas appropriately, especially when an adverbial clause begins a sentence or when an adjectival clause is non-restrictive. Consult grammar resources for specific punctuation rules.
Finally, ensure that the subordinate clause genuinely adds necessary information. If it’s redundant or doesn’t contribute to the meaning, consider removing it for greater impact.
Practice Exercises: Mastering Subordinate Clauses
To solidify your understanding, actively practicing identifying and constructing subordinate clauses is essential. Begin by analyzing sentences from your reading material, pinpointing the subordinate clauses and their types.
Exercise 1: Identification
Read the following sentences and identify the subordinate clause in each, stating whether it is adverbial, adjectival, or noun. Also, identify the introductory word.
1. The novel that she recommended was captivating.
2. We will leave when the sun sets.
3. Whoever finishes first gets a prize.
4. Although he was nervous, he delivered a strong speech.
5. I don’t know where they went.
Sentence 1: “that she recommended” (Adjectival, introduced by ‘that’).
Sentence 2: “when the sun sets” (Adverbial, introduced by ‘when’).
Sentence 3: “Whoever finishes first” (Noun, acting as subject, introduced by ‘Whoever’).
Sentence 4: “Although he was nervous” (Adverbial, introduced by ‘Although’).
Sentence 5: “where they went” (Noun, acting as direct object, introduced by ‘where’).
Exercise 2: Sentence Combination
Combine the following pairs of sentences into one complex sentence using a subordinate clause. Ensure correct punctuation.
1. The concert was cancelled. There was a storm.
2. She is a talented musician. She practices every day.
3. The old house stood on a hill. My grandparents lived there.
4. He missed the train. He woke up late.
5. The book is on the table. I told you about it.
Possible combinations:
1. The concert was cancelled because there was a storm.
2. She is a talented musician who practices every day.
3. The old house, where my grandparents lived, stood on a hill.
4. He missed the train because he woke up late.
5. The book that I told you about is on the table.
Exercise 3: Creating Sentences
Write your own sentences using the following introductory words to create different types of subordinate clauses.
1. Since (Adverbial clause of time or reason)
2. Which (Adjectival clause)
3. That (Noun clause)
4. If (Adverbial clause of condition)
5. Who (Adjectival clause)
Example for ‘Since’: “Since you’re already here, you might as well stay for dinner.” (Adverbial of reason)
Example for ‘Which’: “My brother, which is a bit of a surprise, is moving to Australia.” (Adjectival, non-restrictive)
Example for ‘That’: “She believes that honesty is the best policy.” (Noun clause, direct object)
Example for ‘If’: “If you study diligently, you will succeed.” (Adverbial of condition)
Example for ‘Who’: “The artist who painted this portrait is famous.” (Adjectival, restrictive)
Advanced Applications: Subordinate Clauses in Sophisticated Prose
Beyond basic identification and construction, understanding how subordinate clauses contribute to sophisticated prose is crucial for advanced writers. They are tools for precision, emphasis, and stylistic elegance.
Complex sentences often employ multiple subordinate clauses. This layering allows for the expression of intricate relationships between ideas, mirroring the complexity of human thought. For instance, an adverbial clause might introduce a condition, which is then further described by an adjectival clause.
The strategic placement of subordinate clauses can also create specific rhetorical effects. Placing an adverbial clause of concession at the beginning, for example, can soften a subsequent strong statement, appearing balanced and thoughtful.
Noun clauses can be used to embed reported speech or complex ideas within a larger sentence structure, allowing for a more integrated discussion of abstract concepts or opinions.
Writers can also manipulate the order of clauses for stylistic variation. While standard order often prevails, occasionally reversing the typical sequence can add emphasis or a unique rhythm to the prose.
Consider how professional writers use them to build arguments. They might introduce a premise with an adverbial clause, follow with a core argument in the independent clause, and then add supporting details using adjectival clauses.
Mastering these advanced applications requires not just grammatical knowledge but also a keen sense of style and purpose. It’s about using subordinate clauses to serve the overall message and engage the reader on a deeper intellectual level.
The Power of Precision: Subordinate Clauses and Clarity
The primary advantage of using subordinate clauses correctly is the enhanced clarity they bring to writing. They allow for the precise qualification and specification of information.
An adjectival clause, for instance, can narrow down a general noun to a specific instance, removing ambiguity. “The student passed” is vague; “The student who studied diligently passed” is specific and informative.
Adverbial clauses provide essential context. Understanding *why* something happened or *when* it occurred is often as important as the event itself. “She succeeded” lacks context; “She succeeded because she had a clear vision” provides the crucial causal link.
Noun clauses allow writers to express complex thoughts as single grammatical units. This prevents sentences from becoming unwieldy lists of simple statements and instead integrates ideas smoothly.
By clearly defining relationships between clauses, writers guide the reader’s interpretation. The reader doesn’t have to guess the connection between different pieces of information; the subordinating conjunction or relative pronoun makes it explicit.
This precision is invaluable in academic, professional, and technical writing where accuracy and lack of ambiguity are paramount. It ensures that the intended meaning is conveyed effectively and efficiently.
Subordinate Clauses in Dialogue and Narrative
In creative writing, subordinate clauses are instrumental in crafting realistic dialogue and compelling narratives. They help characters sound natural and allow for the detailed description of settings and events.
Dialogue often features shorter, more direct sentences, but subordinate clauses can be used to show a character’s thought process or provide background. A character might say, “I didn’t go because I was afraid of what might happen.”
Narrative descriptions benefit immensely from adjectival clauses. “The man who wore a faded blue hat stood by the window” provides more visual detail than “The man stood by the window.”
Adverbial clauses can control the pacing of a story. “When the clock struck midnight, the spell was broken” creates a sense of dramatic timing.
Noun clauses can reveal a character’s internal state or beliefs. “She wondered if he would ever return.” This internal thought is conveyed concisely.
The way characters use subordinate clauses can also reveal aspects of their personality or education level. A highly educated character might use more complex subordination than one with less formal schooling.
By skillfully weaving subordinate clauses into their prose, authors can create richer, more immersive worlds for their readers.
Conclusion: The Enduring Importance of Subordinate Clauses
Subordinate clauses are indispensable components of effective sentence construction. They enable writers to express complex relationships between ideas, add descriptive detail, and convey nuance.
From clarifying cause and effect with adverbial clauses to specifying subjects with adjectival clauses, their functions are diverse and critical. Noun clauses further expand the possibilities, allowing abstract concepts to be integrated seamlessly.
Mastering subordinate clauses requires practice and attention to detail, particularly regarding their identification, function, and punctuation. Avoiding common pitfalls like fragments and ambiguity is key to their successful application.
Ultimately, a strong command of subordinate clauses empowers writers to communicate with greater precision, sophistication, and engaging clarity, transforming ordinary sentences into powerful expressions of thought.
