In general, avoid unnecessary capitals.

Some basic principles:
Proper Nouns: Capitalize nouns that identify a specific person, place, or thing:
♦ John, Mary, America, Boston, Germany.

Some common nouns receive proper noun status when they are used as the name of a particular entity: ♦ General Electric, Gulf Oil.

Lowercase these common nouns when they stand alone in subsequent references: the party, the river, the street.

Lowercase the common noun elements of names in plural uses: the Democratic and Republican parties, Main and State streets, lakes Erie and Ontario.

Exception: plurals of formal titles with full names are capitalized: Presidents Jimmy Carter and Gerald R. Ford.

Colons and
Semicolons

Top

 

colon (:) The most frequent use of a colon is at the end of a sentence to introduce lists, tabulations, texts, etc.

Capitalize the first word after a colon only if it is a proper noun or the start of a complete sentence:
♦ He promised this: The company will make good all the losses.

The colon often can be effective in giving emphasis:
♦ He has two hobbies: eating and sleeping.

Semicolon (;) Use semicolons to separate elements of a series when the items in the series are long or when individual segments contain material that also must be set off by commas:
♦ He is survived by a son, John Smith, of Chicago; three daughters, Jane Smith, of Wichita, Kansas, Mary Smith, of Denver, and Susan, of Boston; and a sister, Martha, of Omaha, Nebraska.

Note that the semicolon is used before the final "and" in such a series.
♦ ... of Boston; and a sister, Martha, of Omaha, Nebraska.

Commas
When using any of the seven coordinating conjunctions (and, but, or, nor, for, so, yet)

Top

Use commas to separate elements in a series. Place commas before the concluding conjunction in a series.

Do not place a comma after “and” when concluding a sentence.
♦ The flag is red, white and blue.
♦ He ate eggs, ham, toast and cereal for breakfast.

Short sentences do not usually need commas.
♦ I drove home but he stayed.
♦ Give me the keys and get in the car.

Use commas when a sentence contains two independent clauses.
♦ Sarah told him again, and really meant it this time, to turn off the television.
♦ Alice will ask John once, but only once, to forgive her.

Commas
In long sentences

Top

Always avoid lengthy sentences. Divide long sentences into short, succinct ones.

Use commas to allow readers to pause and take a breath.
♦ Joe wanted to go back to school to earn a college degree but, he couldn’t afford to quit his job and lose his health care benefits.
♦ Christmas is still months away but, it's not too early to start shopping because it'll be here before you know it.

Dashes

Top

 

Use dashes to denote an abrupt change in thought in a sentence or an emphatic pause: 
♦ Through her long reign, the queen and her family have adapted — usually with style and grace — to the changing taste of the time.

Add a space on both sides in the dash.

Note: Hyphens are short horizonal lines (-). Dashes are long (—). Use the Special Character function in the Edit Content toolbar to add the correct —.

Hyphen

Dates

Top

On Enterprise Web, dates are written Weekday, Month, Day, Year

Write the entire word for the day. Abbreviate months.

Exclamation Marks
One is enough.

Top

Use exclamation marks ( ! ) to express a high degree of surprise, incredulity or other strong emotion.

Avoid Overuse: End mildly exclamatory sentences with a period.

One exclamation mark is enough in headings and body copy. Multiple marks look like warnings!!!

Numbers
In text

Top

Use figures in text for quick comprehension.

♦ The Bowling Center is has 18 regular lanes and 2 bumper lanes.

Don’t repeat numbers:
  - Wrong: There are (4) four camping areas on post.

In general, use figures to keep web text short. Always use figures in lists and tables.

In sentences, use a combination of figures and words for large numbers.

♦ 25 thousand viewers watched the TV show.
♦ Hundreds gathered to see the fireworks display.

Parentheses
How to use, punctuation

Top

The “AP Stylebook” says parentheses are jarring to readers and disrupt comprehension. Write so that you don’t need them. But, if you must use them:

Rule 1. Use parentheses to enclose information that clarifies or is used as an aside.
♦ He finally answered (after taking several minutes to think) that he did not understand the question.

Or, use commas to avoid using parentheses:
♦ He finally answered, after taking several minutes to think, that he did not understand the question.

If material in parentheses ends a sentence, the period goes after the parentheses.
♦ He gave me a nice bonus ($500).

Rule 2a. Periods go inside parentheses only if an entire sentence is inside the parentheses.
♦ Please read the analysis. (You'll be amazed.)

Or, it’s often acceptable without an enclosed period:
♦ Please read the analysis (you'll be amazed).

Rule 2b. Take care to punctuate correctly when punctuation is required both inside and outside parentheses.
♦ You are late (aren't you?).

Note the question mark within the parentheses. The period after the parentheses is necessary to bring the entire sentence to a close.

Rule 4. Commas are more likely to follow parentheses than precede them.
  - Wrong: When he got home, (it was already dark outside) so he went to bed.
  - Right: When he got home (it was already dark outside), so he went to bed.

Plurals
With numbers

Top

♦ The airline has two 727s.
♦ Temperatures will be in the low 20s tonight.

Note that the number id spelled out before before the digits. Do this to avoid a jumble of "number soup".

Quotation Marks and Punctuation
Placement in text

Top

Run-on sentences
Don’t do it.

Top

Write sentences that can be spoken in one breath. Evaluate paragraphs and break long sentences up. Multiple short sentences are easier to understand.

♦ Run-on sentences that lack punctuation tend to wear readers out and combine so much information that by the time the phrase is finished the reader is confused and annoyed and that’s never a good thing to do.

Times

Use figures except for noon and midnight. 12 p.m. is noon and 12 a.m. is Midnight.

♦ 11 a.m.
♦ 1 p.m.  

Use a colon to separate hours from minutes:
♦ 10:30 a.m.
♦ 6:45 p.m.

Use a hyphen without spaces to join times in the same day part.
