What is a sentence fragment, and how do I fix it?
A sentence fragment is an incomplete thought captured in an incomplete sentence; usually, either the subject or the predicate (the verb phrase) is missing. Because it’s an incomplete sentence and therefore an incomplete thought, it must be made complete, either by attaching it to the sentence immediately before or after it OR by adding the missing element.
Here’s an example of a sentence fragment:
While running for President.
Because we don’t get the information about who is running for President—that is, because we’re missing a subject— the idea is incomplete and needs revision. Add a subject!
Revised: While running for President, my dog got a lot of attention and ended up getting her own Twitter account to run her campaign.
What are comma splices and run-ons, and how do I fix them?
A comma splice and a run-on sentence are both results of inaccurate punctuation between two independent clauses (or sentences). A comma splice happens when two sentences are linked together with a comma; a run-on is created when two sentences are run together with no punctuation between them at all. To fix them, identify where the two sentences meet and insert the appropriate punctuation, such as a semicolon, a colon, or a comma with a conjunction.
Example of a comma splice:
I wasn't ready for classes to begin, they began anyway.
Revised by adding a comma + conjunction:
I wasn't ready for classes to begin; but they began anyway
What is parallel structure used for, and how do I create it?
Parallel structure provides the writer and the reader with a sense of balance and arrangement, and as such it’s an invaluable tool for writers who need to explain or argue. Parallel structure sets two or more items together that are matched in verb tense or grammatical structure, such as the famous phrase By the people, of the people, and for the people. You can create parallel structures by looking for the places where two ideas, words, or phrases appear close to each other and then modifying them so that their forms match as closely as possible.
Example: I couldn't find room to study in the Library, or a quiet place at my dorm.
Notice that "in the library" and "a quiet place at my dorm" aren't parallel. Let's make them parallel:
Revised: I couldn't find a place for quiet study in the Library or in my dorm.
Can I start sentences with “there are” or “it is”?
Yes. But this sort of sentence opening is often wordy and overused, and many professors don’t like this opening precisely because it is so often used. You can start sentences with these constructions when you’re drawing attention to what happens after the be-verb: It is with great sadness that we announce the death of rock and roll legend David Bowie.
Another example where the “there is” opening would work well is There is no better way to express love than with flowers. But you wouldn’t want to write It is a long time since the Civil War days. The first two examples deliberately delay the really important element of the sentences: David Bowie's death and the best way to express love. The third example, however, uses “it is” just to take up space; there’s no reason for it there.
What is passive voice, and when can I use it?
Passive voice refers to how sentence elements work together. We usually read sentences that say X is doing Y. In other words, X is the agent of the sentence, and X’s activity is Y. This active sentence therefore moves along well and doesn’t have to pause or slow down.
A passive sentence, however, delays a bit: Y was done by X. X is still the agent, and the activity is still Y—but the reversal of the order puts the action first, rather than the agent. The delay effect is being caused by the passive voice. In some sentences, we don’t get an actor at all: the classic example is mistakes were made. You can use this when you're not sure who was making the mistakes or if you want to hide who was making the mistakes.
You can use passive-voice sentences when the agent of the sentence isn’t necessary or important: The law was passed, and everyone was happy. In this particular example, it doesn’t really matter who passed the law—what matters is that everyone was happy about it.
How formal do I have to be in college writing?
Students ask professors and tutors all the time whether they can use “I” in an essay, or whether it’s all right to write with contractions. The questions make sense, because the rules may change depending on the professor, the discipline, and the class. The smart student asks when they aren’t sure. The short answer is that your writing in college should be as formal—without sounding artificial—as your assignment. A research project is considerably more formal than, say, a journal entry. Your assignment sheet and your professor are your best guides to how formal you should sound.
Will using a thesaurus make me sound better?
You can try this approach to “sounding better,” but it probably won’t work. We want you to increase your vocabulary by learning to incorporate words that you’re coming across in your studies, not by artificially adopting words that sound big or important. When you use words that you don’t really own, that aren’t really a part of your vocabulary, you sound stiff and awkward.
Most professors will want you to sound like you, not like you swallowed a dictionary. Therefore, use a thesaurus only to find the word you’re looking for, not to find any word to use in a pinch. Often, words may be synonyms in a thesaurus, but have different connotations that can completely change the meaning of the sentence if used. Because of this, it is important to either check with a peer, a tutor, or a professor whether or not the word is appropriate or avoid using words you do not have completely incorporated into your vocabulary already.
Will my spell check and grammar check be enough to catch errors?
No. Your spell check will catch words that it doesn’t recognize. That is its primary function, so you have to keep your eyes sharp. Your spell check will catch typos, but it will not tell you when the word itself is wrong—only if the word is spelled incorrectly. Your grammar checker may flag sentences as incorrect that are in fact correct. Don’t rely on the checker to do your grammar work for you.
Can I start sentences with “and” or “but” or “because”?
Yes. The short explanation is that a lot of grammar rules we used to think of as “rules” are determined by the users of those rules, and when enough of those users change a rule, the rest of us follow. Starting sentences with “and” and “but” is an example of that kind of rule.
Technically we would say “Can we start sentences with conjunctions?” and the traditional answer would be “Sentences should never start with conjunctions.” But modern users have realized that starting sentences with “but” tends to add just a bit of emphasis to the sentence. “And” at the start of a sentence has a similar effect. Different disciplines feel differently about this question. Poetry, casual or reflective writing, and many other disciplinary kinds of writing encourage the individual voice being displayed by a careful choice of conjunctions. Professors in natural sciences, history, or economics may expect you to write more formally.
