Use a comma to set off an individual’s hometown when it is placed in apposition to a name, whether "of" is used or not: Chuck Luce, of Port Chester, N.Y.; Ross Mulhausen, New Orleans.
All references to honorary degrees should specify that the degree was honorary. Do not use Dr. before the name of an individual whose only doctorate is honorary. When indicating honorary degrees after a name, use "Hon." followed by the class year.
Jane Smith ’85 received an honorary Doctor of Humane Letters degree from Puget Sound in 1990.
Jane Smith ’85, Hon.’90 returned to campus for Homecoming and Family Weekend.
Jane Smith ’85, Hon.’90 is no relation to John Smith Hon.’72.
"Hopefully" means "in a hopeful manner." Do not use it to mean "it is hoped," "let us hope," or "I hope." Incorrect: Hopefully we will have funding in place soon. Correct: We hope to have funding in place soon.
The rules in prefixes apply, but in general, no hyphen: hyperactive, hypercritical.
Note: Hyphenation sometimes must be determined on a word-by-word basis. Many words that used to be hyphenated, such as "goodbye," now have preferred spellings without the hyphen. If you plan to use a hyphenated word, it is always a good idea to check it first in this guide and in Webster’s New World College Dictionary.
- compound modifiers
Generally speaking words become hyphenated when they are made into compound modifiers—two or more words that express a single concept. Typically compound modifiers immediately precede the noun they modify:
These same modifiers are not hyphenated when they fall after the noun they modify in the sentence:
The hotel we stayed in was top notch.
We visited a church with architecture from the 14th century.
Many residents of this community are Japanese American.
- dual heritage
In general when indicating dual heritage with a compound modifier, hyphenate (African-American student, Mexican-American tradition); do not hyphenate in other cases (Sixteen percent of the freshman class is African American.)
- en dash vs. em dash
- to show range
To separate a range of numbers (12–24), use an en dash, which is roughly the width of a capital “N,” slightly longer than a hyphen and shorter than an em dash. Do not include spaces before or after the en dash. On a Macintosh computer, create using “Option” plus “dash”; on a PC create using <Alt> plus the numbers 0150 on the right-side number pad.
- to set text apart
To set off interruptions in text (The girls waited—wiggling in their seats—for the movie to begin.), use an em dash, which is roughly the width of a capital “M,” twice the size of a hyphen and slightly longer than an en dash. Do not include spaces before or after the em dash. On a Macintosh computer, create using “Option” + “shift” + “dash”; on a PC create using <Alt> + "0151" on the right-side number pad.
Note: When using Microsoft Word, from the “Insert” drop-down menu, chose “Symbol” then “Special Characters” to insert either an en dash or em dash into the body of your text.
Generally do not hyphenate when using a prefix with a word starting with a consonant. Three rules are constant, though they yield some exceptions to first-listed spellings in Webster’s New World College Dictionary:
See separate listings for commonly used suffixes in the body of this style guide, or:
- Follow Webster’s New World College Dictionary for words not listed in the style guide.
- If a word combination is not listed in Webster’s New World College Dictionary, use two words for the verb form; hyphenate any noun or adjective forms
- suspensive (multiple) hyphenation
