Combining Two Short Sentences Into One Longer Sentence (Grade 10 NSC Matric English HL): Revision Notes
Combining Two Short Sentences Into One Longer Sentence
Why is sentence combining important?
Learning to merge shorter sentences into longer, more sophisticated ones is a vital writing skill. When you write essays, reports, or exam answers, your work needs to flow smoothly and demonstrate mature expression. By combining sentences effectively, you create writing that sounds natural and engaging rather than jerky and disconnected.
There are two main benefits to mastering this skill:
- Improved writing fluency: Your work will read more smoothly, helping your ideas connect naturally. This makes your writing easier to follow and more pleasant to read.
- Better sentence variety: Instead of producing numerous short, repetitive sentences, you'll craft more complex structures that show sophisticated language use. This prevents your writing from sounding choppy or simplistic.
Exam Tip
The NSC English exams often test your ability to combine sentences correctly. You may need to rewrite two separate sentences as one, so practising these methods will help you gain easy marks.
Methods for combining sentences
Using 'but'
The word 'but' is a coordinating conjunction that links two contrasting or opposing ideas together. When you join sentences using 'but', you're showing that the second idea differs from or contradicts the first.
An important technique when combining sentences is to use pronouns (words like 'he', 'she', 'they', 'him', 'her', or 'it') instead of repeating the same nouns. This avoids awkward repetition and makes your writing flow better.
Worked Example: Combining with 'but'
Original sentences:
- "The mother loved her child dearly."
- "Poverty forced the mother to give the child up for adoption."
Combined version:
- "The mother loved her child dearly, but poverty forced her to give him/her up for adoption."
Analysis: Notice how 'the mother' becomes 'her' and 'the child' becomes 'him/her' in the combined sentence. This substitution prevents repetition whilst maintaining clarity.
Punctuation Rule
When using 'but', place a comma before it to separate the two clauses correctly.
Using 'who'
The relative pronoun 'who' is specifically used when you want to add extra information about a person. It helps you join two sentences that both describe the same individual, creating a more detailed and flowing sentence.
When you use 'who', you're embedding one sentence inside another. The clause introduced by 'who' provides additional details about the person mentioned in the main part of the sentence.
Worked Example: Combining with 'who'
Original sentences:
- "Miriam Makeba was one of the greatest performers South Africa has ever produced."
- "Miriam Makeba spent many years in exile."
Combined version:
- "Miriam Makeba, who was one of the greatest performers South Africa has ever produced, spent many years in exile."
Analysis: The information about Miriam Makeba being a great performer is inserted into the sentence using 'who', whilst the main point about her years in exile remains the focus.
Punctuation with 'who'
Use commas before and after the 'who' clause when the information is additional rather than essential to identifying the person.
Understanding complex sentences
When you combine sentences using words like 'who', 'when', or 'if', you create what is called a complex sentence. Understanding the structure of complex sentences will help you use them correctly.
Complex Sentence Structure
A complex sentence contains two types of clauses:
-
Main clause: This is the independent part of the sentence that can stand alone as a complete thought. It expresses the primary idea and makes sense by itself.
-
Subordinate clause (also called a dependent clause): This part cannot stand alone. It depends on the main clause to make complete sense and provides additional information.
Memory Aid: Think "MAIN can stand alone" and "SUBordinate SUPPORTS the main idea."
Worked Example: Breaking Down a Complex Sentence
Full combined sentence: "Miriam Makeba, who was one of the greatest performers South Africa has ever produced, spent many years in exile."
Breaking it down:
- Main clause: "Miriam Makeba spent many years in exile." ✓ (This makes sense on its own)
- Subordinate clause: "who was one of the greatest performers South Africa has ever produced" ✗ (This cannot stand alone and needs the main clause)
Key insight: The main clause carries the central message, whilst the subordinate clause adds extra detail, context, or description.
Using 'when'
The subordinating conjunction 'when' connects sentences that have a time relationship. Use 'when' when you want to show that two events are related through timing—one happened at the same time as, before, or after the other.
Worked Example: Combining with 'when'
Original sentences:
- "I saw Mark again after his graduation."
- "Mark was feeling great."
Combined version:
- "When I saw Mark again after his graduation, he was feeling great."
Analysis: The combined sentence shows that these two events occurred at the same time. Using 'when' makes the temporal connection clear and creates a smoother, more sophisticated sentence.
Note: The pronoun 'he' replaces 'Mark' to avoid repetition.
Punctuation Tip
When the 'when' clause comes first in the sentence, use a comma to separate it from the main clause.
Using 'if'
The subordinating conjunction 'if' joins sentences to express a condition or show a cause-and-effect relationship. Use 'if' when you want to indicate that one thing depends on another thing happening first.
Worked Example: Combining with 'if'
Original sentences:
- "Your health improves."
- "You stop eating junk food."
Combined version:
- "If you stop eating junk food, your health will improve."
Analysis: The combined sentence shows that the health improvement is conditional on stopping junk food. The 'if' clause presents the condition, whilst the main clause presents the result or consequence.
Note: Often when combining with 'if', you may need to adjust verb tenses (like changing "improves" to "will improve") to make the conditional meaning clear.
Remember!
Key Points to Remember:
-
Sentence combining improves your writing: It creates better flow and prevents choppy, repetitive sentences that sound immature.
-
Choose the right connecting word: Use 'but' for contrast, 'who' for people, 'when' for time relationships, and 'if' for conditions.
-
Use pronouns to avoid repetition: Replace repeated nouns with pronouns like 'he', 'she', 'they', 'it', 'him', or 'her' to make your writing smoother.
-
Understand clause structure: Complex sentences have a main clause (can stand alone) and a subordinate clause (cannot stand alone).
-
Mind your punctuation: Place commas correctly—before 'but' when joining two clauses, around non-essential 'who' clauses, and after introductory 'when' or 'if' clauses.
