Sentence strength and variety (grammar support)
Part 3: chapter 11
Questions to consider
A. What elements make writing more interesting and accessible to readers?
B. How do writers improve the quality of their work beyond presenting strong content?
Variety in writing is critical in maintaining the interest and attention of the reader, especially when the audience is broader than one’s own department. As writers produce sentences and combine them into paragraphs, they must determine the relationships between the ideas. Specifically, research writers consider whether their ideas are of equal importance and what type of emphasis they need on particular information.
Sentence combining through coordination
Connecting sentences with coordinate or subordinate clauses creates more coherent paragraphs, and in turn, produces more effective writing. A compound sentence can join two independent clauses that contain related ideas of equal importance.
Simple sentences: I spent my entire paycheck last week. I am staying home this weekend.
In their current form, these sentences contain two separate ideas that may or may not be related. Am I staying home this week because I spent my paycheck, or is there another reason for my lack of enthusiasm to leave the house? To indicate a relationship between the two ideas, we can use the coordinating conjunction so.
Compound sentence: I spent my entire paycheck last week, so I am staying home this weekend.
The revised sentence illustrates that a cause connects the two ideas. Notice that the sentence retains two independent clauses (I spent my entire paycheck; I am staying home this weekend), each can stand alone as a complete idea.
Coordinating Conjunctions
A coordinating conjunction is a word that joins two independent clauses. The most common coordinating conjunctions are for, and, nor, but, or, yet, and so. Note that a comma precedes the coordinating conjunction when joining two clauses.

I plan to stay home, and I will complete an essay for class. |
Jessie isn’t going to be at the dance. |
nor (indicates a negative) |
Tom won’t be there either. |
Jessie isn’t going to be at the dance, nor will Tom be there. |
The fundraisers are hoping for a record-breaking attendance. |
but (indicates a contrast) |
I don’t think many people are going. |
The fundraisers are hoping for a record-breaking attendance, but I don’t think many people are going. |
I might go to the next fundraising event. |
or (offers an alternative) |
I might donate some money to the cause. |
I might go to the next fundraising event, or I might donate some money to the cause. |
My parents are worried that I am antisocial. |
yet (indicates a reason) |
I have many friends at school. |

so (indicates a result) |
By staying home I will save money. |

Extension: relationships between ideas
Build better, more interesting sentences with:
coordination – joining two related ideas of equal importance; and
subordination – joining two related ideas of unequal importance.
Conjunctive Adverbs
Another method of joining two independent clauses with related and equal ideas is to use a conjunctive adverb and semicolon. A conjunctive adverb is a linking word or phrase that demonstrates a relationship between two clauses. An example and its revision:
Original sentences: Bridget wants to take part in the next Olympics. She trains every day.
Revised sentence: Bridget wants to take part in the next Olympics; therefore, she trains every day.
The revised sentence explains the relationship between Bridget’s desire to take part in the next Olympics and her daily training. Notice that the conjunctive adverb comes after a semicolon that separates the two clauses and is followed by a comma.
Review the following chart of some common academic conjunctive adverbs with examples of how they are used:
Function | Conjunctive Adverb | Example |
Addition | also, furthermore, moreover, in addition | Alicia was late for class and stuck in traffic; furthermore, her shoe heel had broken and she had forgotten her lunch. |
Comparison | similarly, likewise | Recycling aluminum cans is beneficial to the environment; similarly, reusing plastic bags and switching off lights reduces waste. |
Contrast | instead, however, conversely | Most people do not walk to work; instead, they drive or take the train. |
Emphasis | namely, certainly, indeed | The Siberian tiger is a rare creature; indeed, there are fewer than five hundred left in the wild. |
Cause and effect | accordingly, consequently, hence, thus | I missed my train this morning; consequently, I was late for my meeting. |
Time | finally, next, subsequently, then | Tim crossed the barrier, jumped over the wall, and pushed through the hole in the fence; finally, he made it to the station. |
Exercise #1
Create two sentences from each pair using first a coordinating conjunction and then a conjunctive adverb.
- Pets are not allowed in Ms. Wallace’s building. She owns several cats and a parrot.
- New legislation prevents drivers from sending or reading text messages while driving. Many people continue to use their phones illegally.
- Many students try to take class notes on a tablet or other device. A great deal of research suggests that taking notes by hand rather than with a keyboard enhances learning and retention.
- The coroner concluded that the young man had taken a lethal concoction of drugs. By the time his relatives found him, nothing could be done.
- The human eyes are drawn to the screens of modern technology. An open laptop can distract classmates as far as 8 feet away.
- Amphibians are vertebrates that live on land and in the water. Flatworms are invertebrates that live only in water.
- Many students, particularly those in competitive graduate programs, struggle to find time to exercise. Research shows that people who exercise are exponentially more productive than those who do not.
- Emmett carefully fed and watered his tomato plants all summer. The tomatoes grew juicy and ripe.
- Many instructors allocate a percentage of the total grade to participation points. Students who participate actively in class generally achieve better grades than students who remain silent.
- When he lost his car key, Oscar attempted to open the door with a wire hanger, a credit card, and a paper clip. He called the manufacturer for advice.
Sentence combining through subordination
Subordination is used to join two sentences with related ideas by merging them into a main clause (a complete sentence) and a dependent clause (a construction that relies on the main clause to complete its meaning). This creates a complex sentence. Coordination allows a writer to give equal weight to the two ideas that are being combined, and subordination enables a writer to emphasize one idea over the other. An example and its revision follows:
Original sentences: Farnaz stopped to help the injured man. She would be late for work.
Revised sentence: Even though Farnaz would be late for work, she stopped to help the injured man.
In the revised version, the independent clause (she stopped to help the injured man) stands as a complete sentence and the dependent clause (even though Farnaz would be late for work) is subordinate to the main clause. Notice that the revised sentence emphasizes the fact that Farnaz stopped to help the injured man, rather than the fact she would be late for work. An alternative version is also possible.
Revised sentence: Farnaz stopped to help the injured man even though she would be late for work.
The meaning remains the same in both sentences, with the subordinating conjunction even though introducing the dependent clause.
Subordinating Conjunctions
A subordinating conjunction is a word that joins a subordinate (dependent) clause to a main (independent) clause.
Punctuation note
If a subordinate/dependent clause precedes the main clause, close it with a comma. If the subordinate clause follows the main cause, no punctuation is generally required.
Some common subordinating conjunctions and examples of how they are used follow.
Function | Subordinating Conjunction | Example |
Concession | although, while, though, whereas, even though | Sarah completed her report even though she had to stay late to get it done. |
Condition | if, unless, until | Until we know what is causing the problem, we will not be able to fix it. |
Manner | as if, as, though | Everyone in the conference room stopped talking at once, as though they had been stunned into silence. |
Place | where, wherever | Rita is in San Jose where she has several important client meetings. |
Reason | because, since, so that, in order that | Because the air conditioning was turned up so high, everyone in the office wore sweaters. |
Time | after, before, while, once, when | After the meeting had finished, we all went to lunch. |
