Format

Format is an important part of the revision process. Format involves the design expectations of author and audience. If a letter format normally designates a date at the top, or the sender’s address on the left side of the page before the salutation, the information should be in the correct location. Formatting that is messy or fails to conform to the company style will reflect poorly on you before the reader even starts to read it. By presenting a document that is properly formatted according to the expectations of your organization and your readers, you will start off making a good impression.

Commas

The comma is probably the most versatile of all punctuation marks. This means you as a writer can use your judgment in many cases as to whether you need a comma or not. It also means that the possible errors involving commas are many. Commas are necessary some of the time, but careless writers often place a comma in a sentence where it is simply not needed.

Commas are used to separate two independent clauses joined by a conjunction like “but,” “and,” and “or.”

Commas are not used simply to join two independent clauses. This is known as the comma splice error, and the way to correct it is to insert a conjunction after the comma.

Commas are used for introductory phrases and to offset clauses that are not essential to the sentence. If the meaning would remain intact without the phrase, it is considered nonessential.

Commas are used to offset words that help create unity across a sentence like “however” and “therefore.”

Commas are often used to separate more than one adjective modifying a noun.

Commas are used to separate addresses, dates, and titles; they are also used in dialogue sequences.

Semicolons

Semicolons have two uses. First, they indicate relationships among groups of items in a series when the individual items are separated by commas. Second, a semicolon can be used to join two independent clauses; this is another way of avoiding the comma splice error mentioned above. Using a semicolon this way is often effective if the meaning of the two independent clauses is linked in some way, such as a cause-effect relationship.

Apostrophes

The apostrophe, like the semicolon, has two uses: it replaces letters omitted in a contraction, and it often indicates the possessive.

Because contractions are associated with an informal style, they may not be appropriate for some professional writing. The business writer will—as always—evaluate the expectations and audience of the given assignment.

When you indicate possession, pay attention to the placement of the apostrophe. Nouns commonly receive “’s” when they are made possessive. But plurals that end in “s” receive a hanging apostrophe when they are made possessive, and the word “it” forms the possessive (“its”) with no apostrophe at all.

Subject-Verb Agreement

The subject and verb should agree on the number under consideration. In faulty writing, a singular subject is sometimes mismatched with a plural verb form, or vice versa.

Verb Tense

Verb tense refers to the point in time where action occurs. The most common tenses are past, present, and future. There is nothing wrong with mixing tenses in a sentence if the action is intended to take place at different times. In faulty or careless writing, however, they are often mismatched illogically.

Split Infinitive

The infinitive form of verb is one without a reference to time, and in its standard form it includes the auxiliary word “to,” as in “to write is to revise.” It has been customary to keep the “to” next to the verb; to place an adverb between them is known as splitting the infinitive. Some modern writers do this all the time (for example, “to boldly go…”), and since all grammar is essentially a set of customs that govern the written word, you will need to understand what the custom is where you work. If you are working with colleagues trained across the last fifty years, they may find split infinitives annoying. For this reason, it’s often best to avoid splitting an infinitive wherever you can do so without distorting the meaning of the sentence.

Double Negative

A double negative uses two negatives to communicate a single idea, duplicating the negation. In some languages, such as Spanish, when the main action in the sentence is negative, it is correct to express the other elements in the sentence negatively as well. However, in English, this is incorrect. In addition to sounding wrong (you can often hear the error if you read the sentence out loud), a double negative in English causes an error in logic, because two negatives cancel each other out and yield a positive. In fact, the wording of ballot measures is often criticized for confusing voters with double negatives.

Irregular Verbs

Most verbs represent the past with the addition of the suffix “ed,” as in “ask” becomes “asked.” Irregular verbs change a vowel or convert to another word when representing the past tense. Consider the irregular verb “to go”; the past tense is “went,” not “goed.”

Commas in a Series

A comma is used to separate the items in a series, but in some writing styles the comma is omitted between the final two items of the series, where the conjunction joins the last and next-to-last items. The comma in this position is known as the “serial comma.” The serial comma is typically required in academic writing and typically omitted in journalism. Other writers omit the serial comma if the final two items in the series have a closer logical connection than the other items. In business writing, you may use it or omit it according to the prevailing style in your organization or industry. Know your audience and be aware of the rule.

Faulty Comparisons

When comparing two objects by degree, there should be no mention of “est,” as in “biggest” as all you can really say is that one is bigger than the other. If you are comparing three or more objects, then “est” will accurately communicate which is the “biggest” of them all.

Dangling Modifiers

Modifiers describe a subject in a sentence or indicate how or when the subject carried out the action. If the subject is omitted, the modifier intended for the subject is left dangling or hanging out on its own without a clear relationship to the sentence. Who is doing the seeing in the first sentence?

Misplaced Modifiers

Modifiers that are misplaced are not lost, they are simply in the wrong place. Their unfortunate location is often far from the word or words they describe, making it easy for readers to misinterpret the sentence.
