"When Words Collide," Kessler and McDonald.
As writers, our words are our tools. Therefore, with every word, phrase, clause and sentence we write, we should be asking, "Is this the right tool for the job?" Is the way we have written a sentence the clearest, most concise way to express what we are trying to say?
There are several danger zones to be mindful of as we are writing for clarity, conciseness and coherence.
WORD CHOICE
The words we choose should communicate just what we mean to communicate--nothing more; nothing less. As noted in "When Words Collide," choosing the correct verb is a matter of grammar; but choosing the right verb is a matter of conciseness and clarity.
- Avoid UP
-
- Bob appointed his uncle to head up the committee.
- Bob appointed his uncle to head the committee.
- The negligent father finally faced up to his responsibilities.
- The negligent father finally faced his responsibilities.
- His incessant questions only served to slow up the meeting.
- His incessant questions only served to slow the meeting.
- Avoid those verbs requiring "up" to complete their meaning. These verbs are not wrong; but they are weak.
-
- She suspected the student was making up the excuse.
- She suspected the student was fabricating the excuse.
- Business has been picking up since the street opened.
- Business has improved since the street opened.
"VERBIZING NOUNS"
- Adding the suffix "-ize" to any noun is usually unnecessary, and it often serves to confuse the reader. Nonetheless, some "-ize" words are useful and provide a particular meaning.
- Before tacking "-ize" onto a noun, subject it to these three tests.
-
- Is it listed in the dictionary as an acceptable word?
- Does it have a unique meaning? (e.g. pasteurize)
- Does it have a sound that it not displeasing?
THAT
- That serves a range of grammatical functions.
-
- Adjective: That man is going to fall off of his bike.
- Demonstrative pronoun: That is the last thing he will do.
- Relative pronoun: Harvard is the university that he wants to attend.
- Conjunction: My brother admitted that he is always wrong.
- As a pronoun & conjunction, thatcan often be eliminated.
-
- My brother admitted he is always wrong.
- Harvard is the university he wants to attend.
- Other times removing that requires a sentence be re-written.
-
- She treasured the boat that was built by her father.
- She treasured the boat her father built.
- To determine if that is necessary, ask these two questions:
1. Can that be eliminated with no change in the meaning of the sentence?
2. Can the clause introduced by that be expressed more concisely?
MISPLACED WORDS
A modifier must point directly and clearly to what it modifies. Place the modifier next to or as close as possible to what it is modifying.
Problem modifiers: only, nearly, almost, just, scarcely, even, hardly and merely.
- ONLY
-
- Only the coach lead the team to victory.
(No one else can lead them) - The coach can only lead the team to victory.
(The coach can't do anything more than lead them.) - The coach can lead only the team to victory.
(The coach can't lead anyone else.) - Just the swimmer missed her chance to compete in the race.
(No one else missed a chance.)
- Only the coach lead the team to victory.
- JUST
-
- The swimmer just missed her chance to compete in the race.
(The swimmer barely or recently missed her chance) - The swimmer missed her chance just to compete in the race.
(The swimmer missed her chance simply to compete) - The swimmer missed her chance to compete in just the race.
(The swimmer missed only once chance to compete: the race. Or she missed the chance to limit her competing to one event: the race.)
- The swimmer just missed her chance to compete in the race.
MISPLACED MODIFIERS
- Phrases and clauses should also be placed next to or near what they modify.
-
- Several of the children were confused by math in the class.
- Rising to their feet, the fight song roared from the fans.
- Joe found a twenty-dollar bill walking home.
DANGLING MODIFIERS
- A modifier "dangles" when what it is supposed to modify is not part of the sentence.
-
- Before going on vacation, the bills need to be paid.
- After cutting the grass, the garden was weeded.
SPLITTING AUXILIARY AND MAIN VERBS AND SPLITTING INFINITIVES
- Split verbs lead to incoherence. In most cases, it is best to keep auxiliary verbs next to the main verb and to avoid splitting infinitives.
-
- The students who have been, for more than a week, waiting for tickets were disappointed with the news.
- The burglar was, as far as the detectives could determine, hiding somewhere in the building.
- Splitting infinitives, though common practice is grammatically incorrect and makes for sloppy writing.
-
- For the information to truly be valuable, he will need to verify the source.
- Sally intended to fully explain the proposal, but she missed the meeting.
SUBJUNCTIVE MOOD
- A mood of the verb (to be) that expresses a condition or supposition that is contrary to fact or highly improbable (a wish).
- It is also used to express: DOUBTS, UNCERTAINTIES, REGRETS, DESIRES.
- With subjunctive mood, use WERE instead of WAS.
-
- If I were rich, I would still teach grammar.
- The students looked at me as if I were insane.
- She wishes she were home in bed instead of in class.
- BUT: --If the ex-convict was involved in the robbery, he
probably has left town.
Make your words count. Don't muddy your writing with jargon, unclear construction and repetition.

STRUCTURAL DIFFICULTIES
SENTENCE FRAGMENT
- A group of words lacking one or more of the following: a subject, a predicate, a complete thought (e.g, a dependent clause).
-
- Although he passed the test.
- "Now his concern is to be a normally functioning human being again. Without the headaches, dizziness, memory loss and lethargy that have been part of his life for too long."
RUN-ON SENTENCE
- Lacks proper punctuation
e.g, Comma Splice:- The professor dismissed the class, the students cheered.
- Options to fix run-ons:
1) Create two sentences
2) Use a semi-colon
3) Use a coordinating conjunction
OVERSUBORDINATED SENTENCE
- Caused by several dependent clauses or one long dependent clause at the start of a sentence. Problem: delays main idea.
- Even though I felt sick and discouraged at the thought of taking the exam, I passed the LSDT.
PASSIVE & ACTIVE VOICE
- The "VOICE" of a sentence indicates the form of the verb.
- PASSIVE VOICE: The subject is acted upon by the verb.
- The test was passed by the student.
- The meeting was led by the president.
- The play was canceled.
- ACTIVE VOICE: The subject is performing an action.
Think: Subject-Verb-Object- The student passed the test.
- The president led the meeting.
- The director canceled the play.
- NOTE: Use of the verb to be (e.g., is, was) does not necessarily mean the passive voice.
- She was managing the store. (active)
- The store was managed by her. (passive)
- She was tired. (indicative)
- TIP: Avoid unnecessary introductory phrases and clauses
- It has been shown by numerous studies that studying improves your chances of passing the LSDT.
- Numerous studies have shown that studying improves your chances of passing the LSDT.
CORRECTING PASSIVE VOICE
- Find the verb in the sentence
- Ask who or what is performing the action.
- Construct the sentence to that the "actor" (subject) performs the action.
- Our conclusion was ignored by the committee.
Verb: ignored
Actor: committee
Re-write: The committee ignored out conclusions. - The infant was rescued from the blaze by his mother.
Verb: rescued
Actor: mother
Re-write: The infant's mother rescued him from the blaze.
If we write it:
His mother rescued the infant from the blaze.
"His" is unclear as a pronoun reference.
- Our conclusion was ignored by the committee.
WHEN PASSIVE VOICE IS JUSTIFIED
- The recipient of the action is more important (prominent) than the performer of the action.
-
- President Clinton was heckled by an unidentified comedian posing as a journalist.
- The actor or performer of the action is unknown, difficult to identify or irrelevant.
-
- The gift was damaged during shipping.
NOTE: In this case, the indicative mood (was) is used to state merely a condition or realistic explanation, not an implausible situation.
PARALLEL STRUCTURE (PARALLELISM)
- Don't mix elements in a phrase or series.
- He enjoys books, movies and driving his car. (NO)
- He enjoys reading books, watching movies and driving his car. (YES)
- Don't mix verbals (e.g., gerunds and infinitives).

- Be consistent with grammatical patterns in a sentence (e.g., verb-adjective-noun pattern of three phrases)
- He vowed to decrease federal taxes, increase social services and strengthen foreign relations.
WORDS THAT ARE ALWAYS A SINGULAR SUBJECT
First it might be helpful to remember that the singular form of all verbs except to be and to have is formed by adding "s" or "es." For example: dives, runs, answers and crashes, presses and tosses.
- When used as a subject or adjective these indefinite pronouns are always singular and, therefore, they take singular verbs.
another |
anybody |
anyone |
anything |
each |
each one |
either |
every |
everybody |
everything |
much |
|
neither |
nobody |
no one |
nothing |
one |
other |
somebody |
something |
someone |
|
|
|
? These pronouns may be used as subjects, and they take a singular verb.
- Everyone has been invited.
- She said that something was all she wanted for her birthday.
- The Democratic leadership suggested two solutions but neither was acceptable to the committee chair.
When they are used as adjectives, the noun they modify always takes a singular verb
- Neither solution works for the committee chair.
- Each tragedy gives the population given less time to recover from the previous shock.
- The number--when used as subject of a sentence (an organized unit)?takes a singular verb.
- The number of tenants without heat is increasing.
- Subjects that stand for definable units of money, measurement, time, organization, food and medical problems always take singular verbs.
- Six months is not enough time.
- Five thousand dollars is the minimum bid.
- Ham and eggs is my favorite meal.
- Singular subject followed by phrases such as together with and as well as take singular verb.
- The tax measure, together with its amendments, has passed.
- When all parts of a compound subject are singular and refer to same person or thing.
- The head of the expedition and mayor of the village was the same person.
- When the subject is followed by the phrase "the only one of."
- Jake is the only one of the runners who has finished.
- BUT: Jake is one of those runners who have finished.
(In this case, Jake is one of many [those] runners. The verb "have" agrees with "those runners" not with Jake.)
WORDS THAT ARE ALWAYS PLURAL SUBJECT
- When a compound subject is joined by a coordinating conjunction (and), it always takes a plural verb if the subjects refer to different persons or things and if the subject cannot be considered a unit.
- Your investments and property are sure to increase in value.
- Indefinite pronouns (both, few, many, several) always take plural verbs.
- Both are acceptable choices.
- "A number" as the subject of a sentence always takes plural verbs.
- A number of tenants are in the building.
- Certain plural subjects always take plural verbs.
- The news media are under attack. (singular of media: medium)
THE COMMA
There are 11 simple rules that govern the comma in AP style. Be aware that this is a particular style. Other styles have different rules for comma use.
1) When the last item in a series is connected by a coordinating conjunction (e.g., and, or, but, nor, for, yet, so), do not use a comma before the conjunction.
- I enjoy golf, football and boxing.
2) Use a comma to separate two independent clauses connected by a coordinating conjunction.
- The UO football team won the game, and the Ducks are going to the Rose Bowl.
3) Remember: A compound predicate (two or more verbs serving the same subject) does not need a comma.
- The man voted today and hoped his candidate would win.
4) Use commas following introductory clauses and phrases and other clauses and phrases that would be confusing without commas.
- In the hassles and headaches of daily life at the University, it is easy to forget how privileged we are to attend college.
- Although she had always been afraid to fly, she loved her flight in a small plane.
- Every day, journalists report the news.
5) Use commas to set off non-restrictive (non essential) clauses, phrases and modifiers from the rest of the sentence.
- The lawn mower that is broken is in the garage.
(Restrictive: Indicates more than one lawn mower) - The lawn mower, which is broken, is in the garage.
(Nonrestrictive: Adds non-essential information about the only lawn mower)
6) Use commas to separate descriptive modifiers of equal rank if the coordinating conjunction is missing.
Tip: If you can use the adjectives interchangeably and can successfully insert a conjunction and between them, they require a comma.
- In an angry, blunt statement, President Clinton chided his opponents.
7) Use commas to set off parenthetical expressions and nominatives of direct address.
- The test, you may recall, was easy.
- She said, "You know, Jan, that the test is today."
- "Jan, where's the car?" "Where's the car, Jan?"
8) Use commas to set off participial phrases that modify some part of the independent clause.
- The runner quit, having cut his toe on a broken bottle.
- The judge, tired of the commotion in the courtroom, made everyone leave.
- Driven by an unquenchable desire to win, Sally often cheated.
9) Do not use a comma to separate two independent clauses that are not joined by a coordinating conjunction. Do not use a comma to introduce a subordinate clause.
- The test was today, we all passed. (WRONG)
- We all passed the test because it was easy. (RIGHT)
10) Do not use a comma to separate a reflexive pronoun.
- The mayor himself will be here today.
11) Do not use a comma to precede a partial quotation.
- The mayor said that his opponent was "one of the worst candidates ever to run for office."
BUT: If the quotation is a full sentence, it should be preceded by a comma. - The mayor said, "John Smith is one of the worst candidates ever to run for office. "
THE SEMICOLON
1) When each item in a series includes commas, a semicolon is used to separate the items.
- The pilots were delighted that the owners approved the new contract, the one with the pay increase; accepted changes to the benefits package, changes that included vision care; and allowed pilots to fly small commuter jets.
2) The semicolon may be used to separate closely related independent clauses that are not connected by conjunctions.
- The sun shone all day; it was a welcome sight.
3) Hence, however, indeed, moreover, still, therefore, thus are conjunctive adverbs. They belong to the second sentence and are not coordinating conjunctions. When used after a semicolon they are followed by commas.
- Steve found it difficult to take advice; however, Bill found it easy to give.
THE COLON
1) When the colon is used to introduce a complete sentence, the first word of that sentence should be capitalized.
- The announcement caught John by surprise: Fans who are standing on the field will be arrested.
2) But when the colon is used to introduce a word, phrase or clause that is not a complete sentence, the first word following the colon should not be capitalized.
- John knew what he had to do when he saw the police: remain calm.
3) Use a colon to introduce a two-sentence (or longer) quotation. Using a comma instead of a colon is incorrect.
- JFK said: "Ask not what your country can do for you. Ask what you can do for your country. "
4) Use a colon to introduce a list of items.
- When choosing a computer, consider these three factors: speed, memory and cost.
5) A colon is unnecessary if you are introducing a short list without the words "the following."
- The voters elected Jones, Smith and Marzone.
THE DASH
- Use a dash to notify the reader of a surprising element at the end of a sentence.
-
- The trapper gave his grandson a coat made of fur?skunk fur.
- Use a dash to announce a list, restatement or an amplification.
-
- The waiter's first recommendation?a sea bass baked in a hazelnut crust?was sold out.
- Her first car?a pink and white pinto with leopard-skin seat covers?should be in a museum.
- He had worked hard?did his coach realize how hard??to improve his free throw shooting.
- Don't use a dash for a simple appositive that doesn't require a dramatic shift.
-
- Her first car, a Dodge Dart, is still running.
THE HYPHEN
Smaller than a dash, the hyphen brings words together rather than setting them apart.
- Use a hyphen to form compound modifiers.
COMPOUND MODIFIER:
The Definition: Two or more words are acting as a single modifier for a noun.
The Clue: They belong together. They are not part of a series that can separately describe the noun. -
- I think Steve is a well-intentioned volunteer.
- Steve is a helpful, supportive volunteer.
- The 20-year-old man was too young to buy alcohol.
The Rule: If you can put "and" between the modifiers and it makes sense, it is not a compound modifier.
The Exception:If the modifier includes an "-ly" adverb, these words alone indicate that they are part of a compound modifier, so a hyphen is redundant.
- Most people think they have a well-developed sense of style.
- Steve has a highly developed sense of style.
The Caveat: But be careful to distinguish between a compound modifier and the same words not used as a modifier.
- His too-small effort couldn't save the game.
- The coat he gave his mother was too small.
QUOTATION MARKS
1) Set off explanatory expressions with commas. In this example, attribution ("the mayor said") is inserted between the dependent clause ("If we ...") and the independent clause, ("we will")
- "If we can win this election," the mayor said, "we will change the future of our great city."
2) Place periods and commas within quotation marks.
- "I don't like cabbage," said Peter Rabbit.
- Peter Rabbit said, "I don't like cabbage."
3) Place a question mark inside quotation marks if the quotation is a question. But if the quoted material is not a question, put the question mark outside the quotation marks.
- He asked, "Do you like me?"
- How can you support somebody who is said to be "on the wrong side of every issue"?
4) Semicolons are placed outside quotation marks.
- The football coach introduced his starting lineup as follows: "Daffy Duck, a great quarterback"; "Pluto, a heckuva fullback"; and "Goofy, a ferocious tackler. "
5) A colon goes outside the quotation marks unless it is part of the quotation itself.
- The man said, "I have but one hobby: eating."
- The man called his friend "every bad name in the book": Slimeball, twit, tiny-brained and nose-wiper were some the most common.
APOSTROPHES & POSSESSIVE NOUNS
If a singular noun does not end in s, add 's
- The delivery boy's truck was blocking the driveway.
- Bob Dole's concession speech was stoic and dignified.
- The student's attempts to solve the problem were rewarded
If a singular proper noun ends in s, add an apostrophe.
- Chris' exam scores were higher than any other students.
If a noun is plural in form and ends in an s, add an apostrophe only, even if the intended meaning of the word is singular (such as mathematics and measles.)
- The instructor asked us to analyze ten poems' meanings.
- The dog catcher had to check all of the dogs' tags.
- It is hard to endure the Marine Corps' style of discipline.
If a plural noun does not end in s, add 's
- Many activists in Oregon are concerned with children's rights.

If there is joint possession, use the correct possessive for only the possessive closest to the noun.
- Clinton and Gore's campaign was successful.
- She was worried about her mother and father's marriage.
- Beavis and Butthead's appeal is absolutely lost on me.
If there is a separate possession of the same noun, use the correct possessive form for each word.
- The owner's and the boss's excuses were equally false.
- The dog's and the cats' owners were in school when the fire broke out.
In a compound construction, use the correct possessive form for the word closest to the noun. Avoid possessives with compound plurals.

- The forest ranger's truck is painted an ugly shade of green.
- Your neighborhood letter carrier's job is more difficult than you imagine.
