Writing Style Guide

Please continue to use this guide until it can be consolidated into the new site at

Clear, consistent writing is critical to the success of any communication project at the university. This guide is designed to help communicators prepare body copy for external university communications intended for general audiences. While authors and editors are encouraged to use this guide, its use is not mandatory.

This guide is just one tool available to campus communicators. Specific entries in this guide supersede guidelines presented in other reference works such as The Chicago Manual of Style, 15th Edition and Webster's New World Dictionary. We recommend that those references be consulted regarding issues not addressed here.

Publications using terms related to specific fields of research and directed at audiences with scientific expertise should continue to use the style guidelines provided by the college, school, institute, department, or particular research discipline.

Campus authors and editors creating news releases are encouraged to use the most current edition of the AP Stylebook and Briefing on Media Law.

In all cases, we trust that the good judgment and common sense of authors and editors will prevail.

We welcome comments, questions, concerns, and suggestions. Use the email link at the bottom of this page.

Abbreviations and Acronyms

General Rules

Use abbreviations and acronyms only when they are familiar to your readers.

Use the full version in the first reference and follow it with the abbreviated form or acronym in parentheses. Subsequent references should be the abbreviated form or acronym.

Capitalize and hyphenate abbreviations based on the source word. No space should appear after internal periods. Use periods sparingly, such as when the abbreviation could be mistaken for a word if periods are omitted.

Campus Name

In text, the first reference to the campus should be: University of Illinois at Urbana-Champaign. Acceptable second references to the campus include Illinois, U of I (for in-state and alumni audiences), and Urbana or the Urbana campus (to distinguish this campus from the Springfield and Chicago campuses). On subsequent references, make sure that the use is consistent.

Do not use UIUC to refer to the campus. View the policy in the Campus Administrative Manual.

Do not capitalize "university" when the word appears by itself as a noun or an adjective. Correct: The University of Illinois at Urbana-Champaign is a world-class research university. The university is one of the largest recipients of National Science Foundation funding in the United States.

Guidelines and Procedures for Naming Campus Facilities and Programs are available in the Campus Administrative Manual.

The word "Illinois" is a singular proper name ending in an s. As such, only an apostrophe at the end is needed to indicate possession. Example: Illinois' athletic teams.

I Hotel and Conference Center

This is the correct spelling

Illini Union

The Illini Union may be referred to as "the Union."

University of Illinois Extension

When referring to University of Illinois Extension as a noun in text, do not use the word "the" before the name.

Correct: The event was sponsored by University of Illinois Extension. Incorrect: The event was sponsored by the University of Illinois Extension.

When using the name "University of Illinois Extension" as an adjective—to describe the local office, Extension foundation, program, etc.—use of the word "the" is appropriate.

Correct: 1. Stop by the University of Illinois Extension office in Nashville. 2. Proceeds will benefit the University of Illinois Extension Education Foundation in Champaign County.

Big Ten Network

The number is spelled out; this is based on the Big Ten Conference. Correct: Big Ten Conference; incorrect: Big 10 Conference.

Residence Halls

On-campus living accommodations for students are referred to as residence halls. Do not use “dormitory” or “dorms.” For reference, the fourth University of Illinois president, Edmund James, instituted the preferred term in 1916 at a speech at the groundbreaking ceremony of the first residence hall on campus.

Corporation Names

The full form of a company’s name should be used; Inc. or Ltd. may be dropped. Examples: B. Dalton Bookseller; Time Inc.; Land O’ Lakes; Shop-O-Clocks.

Geographical Terms

When they stand alone, spell out the names of states and U.S. territories and possessions.

Spell out the names of states, territories, or possessions when they follow the name of a city or other capitalized geographical term. Example: Chicago, Illinois. When it is necessary to save space, the abbreviations listed below can be used. Do not abbreviate Alaska, Hawaii, Idaho, Iowa, Maine, Ohio, or Utah:

Ala., Ariz., Ark., Calif., Colo., Conn., Del., Fla., Ga., Ill., Ind., Kan., Ky., La., Md., Mass., Mich., Minn., Miss., Mo., Mont., Neb., Nev., N.C., N.D., N.H., N.J., N.M., N.Y., Okla., Ore., Pa., R.I., S.C., S.D., Tenn., Tex., Vt., Va., Wash., W. Va., Wis., and Wyo.

Only use post office abbreviations in complete addresses that contain a ZIP code. See the current ZIP Code Directory for official Postal Service abbreviations. Example: Champaign IL 61820.

Spell out the names of countries. The abbreviation U.S. is acceptable when used as an adjective. Examples: foreign policy of the United States or U.S. foreign policy.


Capitalize the initial letters of the first word; the rest of the headline should follow sentence format.

Names and Titles

Use periods after both first initials if the first name is hyphenated (J.-P. Mathy).

Use periods with no space if the initials are used instead of a first name. Example: E.B. Jones.

Don't use periods or spaces when initials are used to refer to a person. Examples: JFK (John Fitzgerald Kennedy) or FDR (Franklin Delano Roosevelt)

Spell out civil or military titles when the title appears with a surname. Example: Lieutenant Colonel Blake. Abbreviate the title with a full name. Examples: Lt. Col. Henry Blake.

Abbreviate social titles Mr., Ms., Mrs., and Dr. when the titles appear before a name.

Use the abbreviations Jr., Sr., II, and III as part of a person’s full name. Examples: Everett McKinley Dirksen, Jr. The abbreviations Jr. and Sr. should appear with commas before and after the element.

Example: Everett McKinley Dirksen, Jr., is not a real person.

There is no need to use commas to set off II and III when used as a part of a name. Example: Everett McKinley Dirksen III is not a real person.

Personal Names and Titles

LL.M (Master of Laws degree), not L.L.M.


Use abbreviations for the time of day in body copy, tables, and footnotes. Do not use capital letters. Example: 2 a.m. or 3 p.m. See the time of day entry.

Use A.D. and B.C. only with a specific year. A.D. appears before the date and B.C. appears after the date. In scientific publications and some popular publications, the terms B.C.E. (before common era) and C.E. (common era) are preferred and appear after the date. Examples: 512 B.C.; in A.D. 1438; 500 years before Christ (not 500 years B.C.); Jerusalem was destroyed in 70 C.E.; writing first appeared in Mesopotamia in about 3200 B.C.E.

Titles of Academic Degrees

Academic degrees generally should not be abbreviated. The following abbreviations for common degrees may be used when space is limited, such as a business card: B.A., bachelor of arts; B.S., bachelor of science; M.A., master of arts; M.S., master of science; Ph.D., philosophiae doctor (doctor of philosophy)

Use lowercase when spelling out degrees. Examples: bachelor of science, bachelor of arts, master’s degree.

Hyphens and Compound Words

Definitions and General Rules

Compounds, or a combination of words regarded as a unit, take three forms: spelled as separate words (open compound); joined by a hyphen(s) (hyphenated compound); and spelled as one word (solid compound).

Campus Style for Hyphens and Compound Words

Examples: campuswide, combined degree program, course work, credit-no credit (Do not use virgule [/]), grade point average, home page, summer session, vice chancellor, vice president. In the case of "advanced level," hyphenate when it is used as an adjective (advanced-level courses).

Telephone numbers

Place the area code in parentheses: (217) 333-1000. If the area code appears in parenthetical text, use hyphens: 217-333-1000.

Prefixes and suffixes

Don’t hyphenate words with a prefix. Example: Preprofessional.

Use a hyphen with prefixes that are not words.  Example: post-master’s degree.


Email, email

Italics and quotation marks

General rules

URLs in running text

When there is a need for emphasis, set off URLS in running text by using italics or boldface. Drop the "http://" element for websites with a URL that includes "www" for brevity's sake. If the URL has no "www," such as, the "http://" element should be dropped:

Do not drop the "https://" element used to indicate a secure site.

Do not break a line on a hyphen or insert a hyphen; it can be misleading. Try to break the URL before or after the discrete units of the URL. If the URL is at the end of a sentence, it is acceptable to add a period.

Commas and periods

Place commas and periods inside quotation marks. Colons and semicolons should be placed outside the quotation marks.

All other punctuation: If the punctuation is part of the quotation, put it inside the quotation marks.  If it’s not, put it outside.

Use one space after periods.

Quotation marks

Quotation marks should be used:

  • to indicate the exact words spoken or published by a person
  • the first time a reference is made to a nickname
  • the first time an ironic or sarcastic phrase is used.


General rules

Spell out the numbers one through nine and use numerals for 10 and up.


Spell out numbers at the beginning of a sentence.

Use numerals in percentages (4 percent, not four percent).

If more than one number is used in a sentence, spell them out unless all are 10 and over.

Ranges: use numerals and an en-dash: 1–10, not one through ten.

Addresses and phone numbers

Spell out words in an address unless space is in short supply.  If so, use the following abbreviations:  Ave., Blvd., Bldg., Ct., Dr., La./Ln., Pkwy., Pl., Rd., Sq., St., Terr.

The directions N.W., S.W., and S.E are abbreviated in an address. North, South, East, and West are not abbreviated.

As part of a name, spell out the word street, or avenue. Example: Green Street Coffee House.


The U.S. preference for styling dates is: month, day, and year without the ordinal letters. Example: January 1, 2006 and not January 1st, 2006.

The year may be abbreviated in informal contexts. Example: class of ’49.

Time of day

To indicate specific times, use numerals with a.m. and p.m.

Delete the zeroes if the time of day is on the hour. Example: 5 p.m. not 5:00 p.m.

Use noon and midnight and do not use 12:00 p.m. and 12:00 a.m.

Spell out the time of day in text unless referring to a precise time. Example: She’s home from class by four.


Delete cents when you have a round dollar amount. Example: $20 instead of $20.00.

Figures should be used for monetary amounts.

Use the word "cents" for amounts less than a dollar and the dollar sign for amounts of more than a dollar.

If the monetary amount is more than a million dollars, use the dollar sign and spell out million, billion, etc.

Decimals and percentages

Figures should be used for percentages unless they start a sentence.

Percent should be spelled out in text. Example: She received a score of 82 percent on her exam.

Zeros can be used before decimal points, but not after, unless they are needed to show exact measurement. Grade point average, however, should always include two decimal places. 3.00 GPA (not 3.0 GPA)



Commas should be used before a conjunction joining two independent clauses in a compound sentence. Example: She wanted to go swimming, but her mom told her to wait.

Use commas to separate two or more adjectives that modify a single noun. Example: She bought a pink, fuzzy sweater.

Commas should be placed inside quotation marks but outside of brackets and parentheses.

In a series of three or more phrases or words, separate all parts of the series with commas. Example: Jessica, Caitlin, and Stephanie went to the store. 


Semicolons should be used in lists whose items include commas. Semicolons should separate closely related clauses.


Use colons to introduce a series or a list. Text following a colon only should be capitalized if it is a complete sentence.


Use periods to end: 

  • a declarative sentence;
  • a quoted passage that also ends a sentence;
  • a list of vertical items if some or all of the list items are complete sentences;
  • a vertical list that is punctuated with commas at the end of each item.

Exclamation points

Use sparingly, to indicate emphatic or emotional statements.


Use apostrophes to show omitted letters, such as in contractions.

When referring to class year, use an apostrophe. class of '89.

An apostrophe and s should be added when forming the possessive of a singular common noun. The possessive of a plural common noun is formed by the addition of an apostrophe only. Example: the dog’s tail, the puppies’ tails.

Use brackets to enclose editorial comments, corrections, explanations, phonetic spellings, and the phrases To be continued and Continued from.

“Pre” words

Spelled closed (prelaw, preprofessional) except pre-Columbian or other such compound words in which the second half is a proper noun.

“Re” words

Spell closed (reentry, reenroll).


Plurals of proper nouns are formed by adding s. If the name ends in s, add es.

The plurals of numbers, multiple letters used as words, and words used as words are formed by adding s alone.

Apostrophes should not be used to form the plural of a proper noun unless it is to indicate possession.


To form the possessive of a singular noun, add an apostrophe and an s. Example: the dog’s bone.

Email addresses in running text

When there is a need for emphasis, set off by using italics or boldface; do not use angle brackets (<>).

Do not break a line on a hyphen or insert a hyphen; it can be misleading.  Generally, try to break before a punctuation mark, moving the “@” or “.” to the next line: publicaffairs

If the email address is at the end of a sentence, it is acceptable to add a period.

Common words

The following style should be used for these words: 

  • bandwidth
  • CD-ROM

Correct Usage

Campus terms


Alumnus is the singular form for a man who has attended a school. The plural is alumni.

Alumna is the singular for a woman who has attended a school. The plural is alumnae.

Use alumni as the plural when referring to both men and women who have attended a school.


Use emeritus when referring to male professors. Use emerita when referring to female professors. Note that this term should not be substituted for "retired." Emeritus/emerita is a special status that must be officially approved by the university. Example: Alan Nathan, a professor emeritus of physics at Illinois.

Other common terms

  • chair
  • class year and degree identification
  • class year/standing
  • degrees with distinction
  • endowed professorships
  • faculty vs. staff
  • fellow, fellowship
  • first-year student vs. freshman*
  • NetID
  • Quad vs. quadrangle
  • Residence hall

*first-year student is preferred because it is possible to still have official status as a freshman while attending classes for a third semester. This is because a student may have dropped or failed a class or did not enroll in enough hours to reach the official number needed to be a sophomore.


A trademark for a software program for setting up and maintaining discussion groups through email.

Science vs. sciences (in departmental and school names)

Pay close attention to the correct usages. Example: Courses are offered in Computer Science and Animal Sciences. Note the correct use in a school name: Graduate School of Library and Information Science, not Graduate School of Library and Information Sciences.

Nonsexist language

Take reasonable steps to avoid unnecessary gender-specific language.

Avoid using a generic masculine pronoun when the antecedent includes both men and women.

Use substitutions for words with masculine markers when possible and logical. Example: firefighter instead of fireman.

Females over the age of 18 should be referred to as women and males over the age of 18 should be referred to as men.

Parallel terms should be used for men and women. Examples: ladies and gentlemen, wife and husband.

Women and men should not be referred to by their roles as wife and husband, mother and father, brother and sister, or son and daughter unless it aids in the comprehension of the content.

Take reasonable steps to avoid unnecessary use of the words "feminine" or "woman" as modifiers. Examples: woman doctor, feminine logic.
