Mastering how to connect independent and dependent clauses is an essential skill for anyone who wants to write with clarity and confidence. Independent clauses can stand alone as complete sentences, while dependent clauses need support to express a full idea.
Knowing how to connect them correctly allows you to create smoother, more varied sentences that flow naturally. It also helps you avoid common grammar mistakes such as fragments and comma splices.
In this guide, you’ll learn practical steps, rules, and examples to improve your writing by combining clauses effectively and purposefully.
How To Connect Independent And Dependent Clauses?
Once your child understands what independent and dependent clauses are, the next step is learning how to connect them properly. This skill is crucial not just for English compositions, but also for comprehension, situational writing, and even oral exams.
Write Your Main Idea (Independent Clause)
Every good sentence begins with a clear main idea. In grammar, this comes from the independent clause. Encourage your child to start by writing down the most important point they want to express.
For example: “The pupil completed her assignment.” This sentence is complete on its own and communicates a full thought.
In school settings, many students make the mistake of rushing to add “fancy” sentence structures without first identifying their main clause. This can lead to incomplete or confusing writing.
By training your child to focus on the independent clause first, you’re helping them anchor their ideas. Once the main clause is secure, adding a dependent clause becomes much easier and more natural.
A simple exercise you can try at home: ask your child to write three short, complete sentences about their day. Each one should have a subject and a verb. These independent clauses will serve as the foundation for building longer, more complex sentences later.
Decide The Relationship You Want To Show
After establishing the independent clause, the next step is deciding what kind of relationship the dependent clause should show. This is where writing gains depth.
Dependent clauses can express cause (because she studied hard), time (after he reached home), contrast (although it was raining), or condition (if the bus is late).
For instance, if your child starts with: “The pupil completed her assignment,” you can guide them to ask:
- Do I want to explain why? → “The pupil completed her assignment because she stayed back after school.”
- Do I want to show when? → “The pupil completed her assignment after she returned from CCA.”
- Do I want to highlight contrast? → “The pupil completed her assignment although she was very tired.”
- Do I want to describe a condition? → “The pupil will complete her assignment if she finishes her chores first.”
This thinking process helps children become more intentional in their writing. Instead of simply stringing words together, they learn to communicate relationships between ideas. In the Singapore classroom, this is particularly useful for compositions, where markers look for sentence variety and logical flow.
At home, parents can reinforce this by asking guiding questions: “Do you want to explain why? Do you want to show when? Do you want to give a condition?” This makes writing more interactive and gives your child practical tools to develop stronger sentences over time.
Choose A Connector That Matches That Relationship
Once your child has decided on the relationship they want to show, the next step is choosing the right connector. A connector is simply a joining word that links the independent clause with the dependent clause.
These can be subordinating conjunctions (such as because, although, if, when), relative pronouns (such as who, which, that), or other linking words depending on the context.
For example:
- To show cause, your child might use because: “She did well because she revised carefully.”
- To show time, they might use when or after: “He went home after he finished his CCA.”
- To show contrast, they could use although: “Although it was late, she continued practising the piano.”
- To show condition, they could use if: “You can go out if you finish your homework.”
- To give extra information, they might use a relative pronoun: “The teacher who explained clearly made the lesson easier to follow.”
Many students in Singapore tend to overuse simple connectors like because or and. While these are correct, relying only on them can make writing repetitive.
By exposing your child to a wider range of connectors, you give them more tools to express ideas precisely. This can make their compositions stand out during exams, as markers often reward variety and accuracy in sentence structures.
At home, you can turn this into a quick game: give your child a short independent clause such as “The class enjoyed the trip.”
Then challenge them to expand it using different connectors: “The class enjoyed the trip because it was well planned,” or “Although it rained, the class enjoyed the trip.” This helps them see how one simple sentence can be transformed in many ways.
Place The Dependent Clause Where It Reads Best
Another important step is deciding where to put the dependent clause. It can appear at the beginning, middle, or end of a sentence, and each choice changes the flow and emphasis.
- Beginning – This placement sets the stage and provides context before the main point.
- Example: “Because it was raining, the football training was cancelled.”
- This style is useful in exams when your child wants to create variety or highlight background information.
- Example: “Because it was raining, the football training was cancelled.”
- Middle – This is often done with relative clauses, which provide extra detail about a noun.
- Example: “The teacher, who has many years of experience, guided the students patiently.”
- This structure adds depth and sophistication, but it must be punctuated correctly with commas when the clause is not essential to the meaning.
- Example: “The teacher, who has many years of experience, guided the students patiently.”
- End – This placement often works well because it allows the main idea to be stated first, followed by additional information.
- Example: “The football training was cancelled because it was raining.”
- This is the most common choice for students, as it feels natural and straightforward.
- Example: “The football training was cancelled because it was raining.”
In Singapore classrooms, teachers encourage students to vary sentence structures rather than using the same pattern repeatedly. By experimenting with different clause placements, your child’s writing will sound more mature and less monotonous.
As a parent, you can guide practice by asking your child to take one pair of clauses and rewrite the sentence in three ways—dependent clause at the start, in the middle, and at the end. For example:
- Start: “Although he was tired, he finished his homework.”
- Middle: “He, although he was tired, finished his homework.”
- End: “He finished his homework although he was tired.”
This simple activity strengthens their awareness of sentence flow and prepares them for both PSLE and O-Level writing tasks, where strong sentence variety can make a real difference in their grades.
Apply Punctuation Correctly
One of the trickiest parts of connecting independent and dependent clauses is knowing where to place commas. The general rule is simple:
- If the dependent clause comes before the independent clause, use a comma.
- Example: “Because the rain was heavy, the football match was postponed.”
- Example: “Because the rain was heavy, the football match was postponed.”
- If the dependent clause comes after the independent clause, no comma is needed.
- Example: “The football match was postponed because the rain was heavy.”
Relative clauses need a little extra care. If the information in the clause is non-essential (extra detail), commas are required: “My teacher, who loves literature, recommended this book.”
If the information is essential to the meaning, then no commas are used: “The teacher who loves literature recommended this book.”
In Singapore exams, many students lose marks for punctuation slips such as comma splices (using a comma alone to join two independent clauses).
For example: “It was late, she kept on reading.” This is wrong because both parts are complete sentences. The correct fix is either to use a connector (“It was late, but she kept on reading”) or separate into two sentences.
Getting punctuation right not only prevents grammar mistakes but also makes your child’s writing clearer and more professional.
Check For Completeness
Another common pitfall students face is leaving a dependent clause “dangling” without support. Remember: a dependent clause cannot stand alone—it must be attached to an independent clause.
For example, “Because he studied hard” is incomplete on its own. A reader will naturally expect more information. The complete version is: “Because he studied hard, he scored well in his exam.”
Encourage your child to test their writing by asking:
- Does this sentence make sense on its own?
- If not, does it have a clear independent clause to complete the idea?
This habit is especially important in PSLE Continuous Writing and O-Level essays, where incomplete sentences (fragments) can pull down the language mark. With practice, your child will learn to “listen” for the missing part and fix it quickly.
Revise For Clarity And Concision
Once the sentence is grammatically correct, the next step is polishing it for clarity (easy to understand) and concision (no extra or unnecessary words). Students often get excited adding connectors and clauses, but too many words can make writing clumsy.
For instance: “Because of the fact that he was late, he missed the bus” can be shortened to “Because he was late, he missed the bus.” The meaning stays the same, but the sentence is tighter and easier to read.
Similarly, choosing precise connectors improves clarity. Instead of always using because, your child might use since or as for variety, provided the meaning is correct. Instead of repeating when for every time reference, they could try after, before, once, or until.
In Singapore classrooms, teachers often emphasise sentence variety as a way to demonstrate maturity in writing. By training your child to revise and refine, they not only avoid common mistakes but also learn to communicate their ideas more effectively—a skill that carries over to every subject, not just English.
Mini Cheat Sheet For Connector Chooser And When You Can Choose Them
When your child is writing compositions or structured answers, the right connector makes all the difference. Think of connectors as “bridges” that link the main idea (independent clause) to the supporting idea (dependent clause).
Choosing the correct one shows examiners that your child can express precise relationships such as cause, time, or contrast.
Below is a simple cheat sheet you can keep handy. It shows the most common relationships students need in their writing, the good choices of connectors, and examples of how they work in a full sentence. You can encourage your child to practise by swapping out connectors to see how the meaning shifts.
| Relationship | Good Choices | Example |
| Cause/Reason | because, since, as | She stayed home because she was feeling unwell. |
| Time | when, after, before, until, once | He revised until the library closed. |
| Contrast | although, even though, while, whereas | Although it was raining, the children continued playing football. |
| Condition | if, unless, provided that | You can join the class trip if you submit the consent form. |
| Purpose | so that, in order that | She spoke clearly so that everyone could understand her. |
| Result/Effect | so…that, such…that | He was so tired that he fell asleep during the lesson. |
| Relative Clause | who, which, that, where, whose | The student who studies diligently often does well in exams. |
This table is not exhaustive, but it covers the connectors most frequently used in the Singapore curriculum from upper primary to secondary school. By learning to choose connectors based on meaning, rather than memorising a single “safe” option, your child will gain the flexibility to handle any exam question.
💡 Tip for parents: Encourage your child to use a variety of connectors across their writing. Examiners look for range and accuracy, and repeating the same word (for example, always using because) can make their writing feel flat. Variety shows confidence and control of the language.
5 Common Mistakes When Connecting Independent And Dependent Clauses (And How to Fix Them)
Even when students know how to form independent and dependent clauses, combining them smoothly is not always easy.
Many children make avoidable mistakes that cost them marks in school compositions, comprehension answers, or grammar exercises. Below, we highlight three of the most common errors, along with clear fixes you can guide your child through.
1. Comma Splice
A comma splice happens when two independent clauses are joined with just a comma, without the right connector. For example:
❌ “I wanted to go for a swim, it was raining heavily.”
This is incorrect because the comma alone is not strong enough to connect two complete ideas. In the Singapore classroom context, such mistakes are often flagged in upper primary grammar exercises or lower secondary compositions.
✅ To fix this, your child should use a subordinating conjunction to show the relationship:
“I wanted to go for a swim because it was raining heavily.”
Alternatively, the sentence could be rewritten into two separate sentences for clarity:
“I wanted to go for a swim. It was raining heavily.”
Encourage your child to always check if both sides of the comma can stand alone. If yes, a proper connector is needed.
2. Fragment
A fragment is an incomplete sentence, often caused when a dependent clause is left standing alone. For instance:
❌ “Because she revised all night.”
This leaves the reader hanging—because what happened? Students in Singapore often lose marks in continuous writing for leaving such incomplete sentences, especially under time pressure during exams.
✅ To correct this, pair the dependent clause with an independent clause:
“Because she revised all night, she felt tired the next morning.”
You can also flip the order:
“She felt tired the next morning because she revised all night.”
Fragments may sound natural when speaking, but in formal writing, they must be completed for accuracy and flow.
3. Misplaced/Ambiguous Relative Clause
Relative clauses (using words like who, which, that, where) need to be positioned carefully, or the sentence becomes confusing. Here’s a common mistake:
❌ “The teacher gave out the worksheets to the students which were printed this morning.”
Here, it is unclear if “which were printed this morning” refers to the worksheets or the students. Such ambiguity can confuse the marker and affect clarity in comprehension answers.
✅ To fix this, place the relative clause directly next to the noun it is describing:
“The teacher gave out the worksheets which were printed this morning to the students.”
Or rephrase for clarity:
“The worksheets, which were printed this morning, were given out to the students.”
Parents can help their children by asking: “Does this extra detail clearly point to the right noun?” If not, the relative clause probably needs to be shifted.
4. Comma Before “That”
One common mistake students make is inserting a comma before the word that. For example:
❌ “She explained, that she was late because of the heavy rain.”
This is grammatically incorrect because that introduces a restrictive clause—information that is essential to the sentence. Unlike which, it should never be preceded by a comma. Teachers in Singapore often circle this error in grammar practice, as it shows a lack of understanding of proper clause structure.
✅ The corrected version would be:
“She explained that she was late because of the heavy rain.”
Parents can remind children that a quick check is: if the clause is necessary to complete the idea, there should be no comma before that.
5. Overusing Dependent Clauses In One Sentence
Some students, especially in upper primary or lower secondary, try to pack too many dependent clauses into one sentence. This makes their writing messy and hard to follow. For instance:
❌ “Because it was raining and because the bus was delayed and since she forgot her umbrella, she was late for school which annoyed her teacher who then scolded her in front of the class.”
This sentence is grammatically possible but far too overloaded for good writing. In the PSLE or O-Level exam, such long-winded sentences are likely to lose marks for clarity and impact.
✅ A better approach is to break the sentence into shorter, clearer parts:
“Because it was raining and the bus was delayed, she was late for school. This annoyed her teacher, who then scolded her in front of the class.”
Encourage your child to focus on one or two key dependent clauses per sentence. If the sentence starts feeling too long, it’s usually a sign that it should be split into two. This makes their writing not only grammatically correct but also easier to read—something markers in Singapore always reward.

Frequently Asked Questions About Connecting Independent And Dependent Clauses
Can An Independent Clause Come After A Dependent Clause?
Yes, an independent clause can follow a dependent clause. When the dependent clause comes first, a comma is usually needed to separate them. For example: Because it rained, the match was cancelled.
Are Relative Clauses Considered Dependent Clauses?
Yes, relative clauses are a type of dependent clause. They begin with relative pronouns such as who, which, or that and give extra information about a noun. On their own, they cannot form a complete sentence.
Is It Correct To Use A Semicolon When Connecting An Independent Clause To A Dependent Clause?
No, a semicolon should not be used in this case. Semicolons only connect two independent clauses that could stand as complete sentences. To link a dependent clause, use a subordinating conjunction or relative pronoun instead.
Does A Dependent Clause Always Need To Follow The Independent Clause?
No, the dependent clause can come either before or after the independent clause. Writers often place it at the beginning to give background or emphasis. For example: Although he was tired, he finished his work.
Should Dependent Clauses Always Be Short?
Not at all—dependent clauses can be short or long. What matters most is that they are clear and do not overwhelm the main clause. Keeping sentences balanced helps maintain readability.
Can Students Practise Connecting Clauses Through Rewriting Exercises?
Yes, rewriting exercises are one of the best ways to practise. Students can take two short, simple sentences and combine them into one complex sentence. This builds flexibility and confidence in using connectors and punctuation correctly.
