At Stetson, we see the following common errors. This section should be your first stop to help you identify the mistakes you’re most likely to be making.
1. Missing comma after introductory element
Problem: It doesn’t seem right but a lot of people still impose their choices on others.A
Problem: If we don’t do something about climate change we won’t be able to survive the way we do now.
If you read the first sentence out loud, you would naturally pause slightly after “right” and before “but.” The effect of the pause is to throw the emphasis on the clause “but a lot of people still impose their choices on others.” That effect is lost without proper punctuation. We can signal the important part of the sentence by putting it at the end of the sentence and separating it from the introductory part with a comma.
The fix is simple: first, identify the MAIN part of the sentence, the part that carries the most important idea. Then, insert a comma between that section and the introductory material that prefaces it. This rule holds in 99% of the sentences-with -introductory-element that you’re likely to be writing, so be sure to get into the habit of placing the comma properly. Any time you lead into your main idea with an introductory clause, you should place a comma between the two.
Revised: It doesn’t seem right, but a lot of people still impose their choices on others.
Revised: If we don’t do something about climate change, we won’t be able to survive the way we do now.
2. Vague pronoun reference
In the following sentences, you should be able to sense a bit of uncertainty—not about the sentence’s meanings, since they’re fairly clear, but about how parts of the sentence relate to other parts. We need your writing to be very precise, and precision includes careful attention to word choice.
Problem: Transmitting radio signals by satellite is a way of overcoming the problem of scarce airwaves and limiting how they are used. (Vague: The “they” could refer to either the scarce airwaves or the radio signals.)
Problem: The University adopted an F-forgiveness plan for students failing courses. This was a good idea. (Vague: What is “this” referring to? It could mean the plan, or the fact that the University adopted it.)
The problem in both examples is a lack of specificity. When you use a pronoun to refer back to a noun, readers need to know precisely which noun you mean us to understand. (The noun you’re referring back to is known as the antecedent.) Every second counts when we’re reading your work, so it’s your job to make sure that your meaning is as clear as you can possibly make it.
The fix is simple: When you’re editing your work after revising it, look for every pronoun and ensure that it refers very clearly to a specific noun phrase in your sentences. You can try using your word program to search for replacing pronouns like “they,” “it,” “this,” and so forth, to see whether you’ve gotten into the habit of using pronouns to refer to vague nouns. When you find pronouns whose antecedents aren’t perfectly clear, your options are to replace them with specific nouns or to edit the sentence’s punctuation and grammar.
Revised: Transmitting radio signals by satellite is a way of overcoming the problem of scarce airwaves and limiting how they the airwaves are used. (replacing a vague pronoun with a specific noun)
Revised: The University adopted an F-forgiveness plan for students failing courses. The new policy was a good idea. (replacing the vague pronoun with more specific nouns)
3. Comma splice
The comma splice sentence happens when students join together two independent clauses—sentences that could stand on their own -- with a comma rather than using a semicolon or a period.
Problem: It never seems fair to me that some students get more financial aid, don’t we all deserve as much assistance as we can get?
Problem: The Commons tries hard to provide the right kinds of food, sometimes they don’t get it right.
The fix is simple: You need to decide what the relationship is between the two independent clauses before you can decide the appropriate punctuation. If the sentences are related, with the second one amplifying or adding to the first, then you can use a semicolon. If the first sentence isn’t really related to the second sentence, you can use a period. If what you want is a slight pause before the start of the second sentence, perhaps for emphasis, then a period is appropriate. Sometimes all you need to add is a conjunction (but, and, or, and yet, for instance).
Revised: It never seems fair to me that some students get more financial aid; I think all deserve as much assistance as we can get!
Revised: The Commons tried hard to provide the right kinds of food, but sometimes they don’t quite get it right.
4. Run On Sentences
Problem: It never seems fair to me that some students get more financial aid we all deserve as much assistance as we can get.
Run on sentences (also called fused sentences) are very similar to comma spliced sentences: they’re composed of two independent clauses, but instead of being connected with a comma, the first sentence runs on into the second one.
The fix is simple: Identify where your two sentences meet and put in a semi colon, a period, or a conjunction to resolve the problem.
Revised: It never seems fair to me that some students get more financial aid; we all deserve as much assistance as we can get.
5. Punctuation with quotation marks
Essential concepts:
-
Quotation marks go around the quoted material, and only the quoted material.
-
The ending punctuation of a quotation can stand in for the ending punctuation of your sentence, but you may have to move it.
Problem: “It was the best of times, it was the worst of times (73).”
Revised: “It was the best of times, it was the worst of times” (73). (note placement of closing quotation marks)
Problem: “It was the best of times, it was the worst of times.” (73)
Revised: “It was the best of times, it was the worst of times” (73). (note placement of ending period)
Problem: “It was the best of times, it was the worst of times. (73)”
Revised: “It was the best of times, it was the worst of times” (73). (note placement of ending quotation marks and period.)
6. Semicolons and Colons
If you don’t already know how to use semicolons and colons, we think you should learn.
A semicolon is used in two ways: to link two complete sentences when the sentences are related, and to separate items in a complex list. For instance:
Example: The dogs are barking; there must be someone in the street.
These two sentences are clearly in a cause/effect relationship: the dogs in the first clause are barking because of the someone in the second clause. We understand the relationship without the semicolon, but the punctuation makes the relationship much clearer.
In the next example, the semicolon separates items in a list.
Example: What really screws up the environment is the combination of greenhouse gases; the lack of attention paid to the problem by the government; and the greed of the big oil companies.
Semicolons in a list set-up are used when the items in the list are more than one or two words. More often, we use a colon to introduce a list.
Colons can also be used to set up an explanation or an amplification of what’s on the left side of the colon. In other words, if the first sentence sets up a sort of expectation in the reader, a colon then offers information that fulfills that expectation. In this example sentence, the colon amplifies what’s on the left with what’s on the right:
Example: The 2008 Presidential election was historically significant: for the first time, the top two candidates for the Democratic nomination were a white woman and a black man.
7. Using quotations that fit your sentences
We allow two ways—and only two ways—to change what appears within the quotation marks. Neither of the ways allows you to quote out of context or in any other way alter the meaning of the quotation; they simply indicate that you have smoothed the way for the reader.
The first is a set of square brackets [ ] to indicate that some words have been altered to fit your sentence grammatically or to clarify meaning.
Example For Inuit…[global] warming is likely to disrupt or even destroy [the Inuit’s] hunting and food-sharing culture as reduced sea ice causes the animals on which they depend to decline, become less accessible, and possibly become extinct.
In this case, the brackets tell us that “global” was not part of the original quotation but also that the context of the original is about global warming. The word has simply been added to clarify. The second set of brackets in this quotation, around “the Inuit‘s” tells us that in the original, the pronoun was probably not specific enough; it might have been “they,” sufficiently vague so that the writer decided to minimize any confusion and simply use a specific noun rather than a pronoun.
The second is the use of ellipsis points, which look like three dots: ….
Ellipsis points serve to indicate to a reader that some words have been removed from the original quotation because they were not important to the writer‘s purpose. Using ellipsis points does not in any way allow the writer to change the source‘s intent, however. Rather, this technique allows the writer to, for instance, omit the middle part of a sentence when it is irrelevant to the point being made:
Example: For Inuit…[global] warming is likely to disrupt or even destroy [the Inuit’s] hunting and food-sharing culture as reduced sea ice causes the animals on which they depend to decline, become less accessible, and possibly become extinct
