Run on sentences
58 flashcards covering Run on sentences for the SAT Reading & Writing section.
A run-on sentence happens when two or more independent clauses—complete thoughts that could stand alone—are incorrectly joined without proper punctuation or conjunctions. This creates a jumbled mess that's hard to read and understand. For instance, "I love running it keeps me healthy" is a run-on because it fuses two ideas without separation, making the sentence unclear and ineffective in writing.
On the SAT Reading and Writing section, run-on sentences appear in questions that test your ability to identify and correct sentence structure errors, often within passage improvement tasks. You'll need to spot common traps like comma splices or fused sentences, where ideas are awkwardly linked, and choose revisions that enhance clarity and flow. Focus on recognizing when to use periods, semicolons, or coordinating conjunctions to properly divide clauses. Always check for multiple independent ideas in a single sentence to avoid these pitfalls.
Terms (58)
- 01
Run-on Sentence
A run-on sentence occurs when two or more independent clauses are joined without proper punctuation or conjunction, making the sentence grammatically incorrect and hard to read.
- 02
Fused Sentence
A fused sentence is a type of run-on where two independent clauses are run together without any punctuation, creating a single long sentence that confuses the reader.
- 03
Comma Splice
A comma splice is a run-on sentence error where two independent clauses are joined by only a comma, without a coordinating conjunction, which fails to properly separate the ideas.
- 04
Independent Clause
An independent clause is a group of words that can stand alone as a complete sentence because it has a subject and a verb and expresses a complete thought, often involved in run-on errors.
- 05
Coordinating Conjunction
A coordinating conjunction, such as and, but, or so, is used to connect two independent clauses properly, preventing run-on sentences by linking equal ideas.
- 06
Semicolon in Run-ons
A semicolon can correctly join two independent clauses that are closely related, serving as an alternative to a period or conjunction to fix run-on sentences.
- 07
Period to Fix Run-ons
Using a period to separate two independent clauses into distinct sentences is a straightforward way to correct a run-on, ensuring each idea is clearly stated.
- 08
Subordinating Conjunction
A subordinating conjunction, like although or because, turns an independent clause into a dependent one, helping to avoid run-ons by making the relationship clear.
- 09
Example: Fused Sentence
In the sentence 'I went to the store I bought milk', two independent clauses are fused without punctuation, creating a run-on that can be fixed by adding a period or semicolon.
- 10
Example: Comma Splice in Daily Life
The sentence 'She loves reading, she goes to the library every day' is a comma splice because it joins two independent clauses with just a comma, which should be followed by a conjunction.
- 11
Example: Correcting with Conjunction
For the run-on 'The dog barked the cat ran away', adding a coordinating conjunction like 'and' makes it 'The dog barked and the cat ran away', properly linking the clauses.
- 12
Example: Semicolon Fix
In 'It was raining hard we stayed inside', this run-on can be corrected to 'It was raining hard; we stayed inside', using a semicolon to connect related ideas.
- 13
Example: Run-on in a Story
The sentence 'The hero fought bravely he defeated the villain' is a run-on fused sentence, which could be fixed by adding 'and' to show the sequence of events.
- 14
Example: Everyday Comma Splice
Saying 'I woke up late, I missed the bus' is a comma splice, as it improperly joins two complete thoughts; adding 'so' would make it correct.
- 15
Example: Fixing with Period
The run-on 'She studied all night she aced the test' becomes two sentences when changed to 'She studied all night. She aced the test', clearly separating the actions.
- 16
Example: Complex Run-on
In 'The team won the game they celebrated wildly it was exciting', multiple clauses are jammed together, making it a run-on that needs breaks like periods or conjunctions.
- 17
Mistake: Using Only a Comma
Students often err by joining independent clauses with just a comma, creating a comma splice, which is incorrect because it doesn't fully separate the ideas.
- 18
Mistake: Omitting Punctuation
A common error is forgetting to add any punctuation between independent clauses, resulting in a fused sentence that runs ideas together without pause.
- 19
Mistake: Overusing And
Some students mistakenly think adding 'and' to every clause fixes run-ons, but it can create overly long sentences if the clauses aren't properly balanced.
- 20
Mistake: Confusing with Lists
Students might treat a run-on as a list by adding commas incorrectly, like in 'I like apples, bananas, oranges', which isn't a run-on but can lead to errors in more complex sentences.
- 21
Mistake: Ignoring Clause Types
A frequent trap is not distinguishing between independent and dependent clauses, leading to run-ons when treating a dependent clause as if it needs no connection.
- 22
Mistake: In Dialogue
Writers often create run-ons in dialogue by not punctuating spoken words properly, such as fusing multiple speakers' lines without breaks.
- 23
Mistake: With Adverbs
Students sometimes think adverbs like 'however' can join clauses alone, but using them without commas or semicolons still results in a run-on.
- 24
Mistake: In Compound Sentences
An error occurs when students forget that compound sentences require proper conjunctions or punctuation, turning them into run-ons.
- 25
Run-on vs. Fragment
Use run-on for sentences with too many joined clauses, but fragment for incomplete thoughts lacking a subject or verb, as run-ons have complete ideas fused together.
- 26
Fused Sentence vs. Comma Splice
Use fused sentence when no punctuation separates clauses, and comma splice when only a comma is used, both being run-on types but differing in their errors.
- 27
Run-on vs. Compound Sentence
Use run-on for incorrectly joined independent clauses, but compound sentence for properly connected ones with conjunctions or semicolons.
- 28
Comma Splice vs. Series
Use comma splice for joining clauses with just a comma, but in a series like 'apples, bananas, and oranges', commas are correct for listing items.
- 29
Run-on vs. Complex Sentence
Use run-on when independent clauses are improperly linked, whereas a complex sentence correctly combines an independent clause with a dependent one.
- 30
Independent vs. Dependent in Run-ons
Use independent clauses in run-ons when they need separation, but dependent clauses can attach to independents without creating errors.
- 31
Edge Case: Run-on with Interrupters
Sometimes a run-on isn't obvious if interrupting phrases like 'for example' are present, but if independent clauses remain fused, it's still an error.
- 32
Edge Case: Long but Correct Sentence
A very long sentence isn't always a run-on if it's properly structured with conjunctions and punctuation, such as a compound-complex sentence.
- 33
Edge Case: In Questions
Run-ons can occur in questions, like fusing two queries without proper punctuation, but they are less common and require careful checking.
- 34
Edge Case: With Quotes
In dialogue, a run-on might not be a run-on if quotes separate speakers, but fusing quoted material with narrative can create errors.
- 35
Edge Case: Exceptions in Poetry
In creative writing like poetry, run-on structures might be intentional for effect, but on the SAT, they are still considered errors.
- 36
Edge Case: When Not a Run-on
A sentence with multiple verbs sharing a subject, like 'She runs and jumps', is not a run-on because it's a single independent clause.
- 37
Strategy: Read Aloud
To spot run-ons on the SAT, read sentences aloud; if it feels like you're saying too many ideas without a breath, it's likely a run-on needing fixes.
- 38
Strategy: Check for Clauses
Identify potential run-ons by counting independent clauses in a sentence; if there are two or more without proper links, revise for punctuation or conjunctions.
- 39
Strategy: Use Process of Elimination
When answering questions about run-ons, eliminate choices that fuse clauses incorrectly, favoring those with periods, semicolons, or proper conjunctions.
- 40
Strategy: Practice with Passages
Improve run-on detection by practicing with SAT passages, focusing on sentences that seem overly long and testing ways to break them apart.
- 41
Strategy: Look for And or But
In multiple-choice, check if 'and' or 'but' is used correctly between clauses; if not, it might indicate a run-on that needs adjustment.
- 42
Strategy: Time Management
Allocate extra time to review sentences for run-ons during the writing section, as spotting them quickly can help avoid errors in your own responses.
- 43
Example: Run-on in a Paragraph
In the passage 'The sun set quickly the stars appeared bright', this run-on fuses two observations, which could be fixed by adding a semicolon for better flow.
- 44
Example: Fixing Multiple Run-ons
The sentence 'We hiked the trail it was steep we reached the top' has two run-ons; correcting it to 'We hiked the steep trail; we reached the top' resolves the issue.
- 45
Example: Comma Splice in Description
Describing something as 'The sky was clear, the birds were singing' is a comma splice, easily fixed by adding 'and' to connect the peaceful scene.
- 46
Comparison: Run-on vs. Simple Sentence
Use run-on for fused independent clauses, but simple sentence for a single clause, as the latter doesn't involve joining multiple ideas.
- 47
Comparison: Fused vs. Correct Join
Use fused sentence for no separation between clauses, whereas a correct join uses punctuation like a semicolon to maintain clarity.
- 48
Mistake: Assuming All Long Sentences Are Run-ons
Students often wrongly label any long sentence as a run-on, but if it's properly punctuated, like with commas in a list, it's not an error.
- 49
Mistake: Misplacing Semicolons
A common trap is putting semicolons between a clause and a list, which creates confusion and might mask a run-on instead of fixing it.
- 50
Mistake: In Formal Writing
In essays, students might create run-ons by stringing thoughts together for flow, forgetting that proper structure is needed even in formal contexts.
- 51
Example: Run-on with Adverbs
The sentence 'He arrived late however he still participated' is a run-on if not punctuated correctly, as 'however' needs a semicolon before it.
- 52
Core: Ways to Correct Run-ons
Run-ons can be fixed by adding a period, semicolon, or conjunction between clauses, or by turning one clause into a dependent one.
- 53
Core: Identifying Run-on Types
Run-ons include fused sentences and comma splices, each requiring specific fixes based on how the clauses are improperly joined.
- 54
Core: Role of Punctuation
Proper punctuation, such as periods or semicolons, is essential in avoiding run-ons by clearly separating independent clauses.
- 55
Core: Common in Student Writing
Run-on sentences frequently appear in student essays due to rushing, but recognizing them improves overall sentence structure on the SAT.
- 56
Comparison: Run-on vs. Run-in Quote
Use run-on for fused clauses in narrative, but run-in quotes for integrated dialogue, which has its own punctuation rules.
- 57
Edge Case: Run-ons in Titles
In titles, what might look like a run-on is often stylistic and not an error, but in SAT passages, it's treated as incorrect.
- 58
Strategy: Mark Suspect Sentences
On the SAT, mark sentences that seem too long and revisit them, using your knowledge of run-ons to choose the best revision option.
