Hyphens

Use hyphens to create compound words.
Be consistent with which words you hyphenate.
The following prefixes normally don't require a hyphen: ante, anti, bi, bio, co, counter, extra, infra, inter, intra, macro, mid, mini, multi, non, over, post (after), pre, pro, pseudo, re, semi, sub, super, supra, trans, ultra, un, under.
- Exception: when a prefix stands alone, it carries a hyphen (over- and underused).
- Other exceptions: the prefix carries a hyphen if the second element is a capitalized word or numeral (un-American, pre-1914) or the compound is a homonym (re-create means to create again, recreate means to take recreation).
When the prefix ends with a vowel and the root begins with a vowel, such as pre-existing, hyphenate.
When a measurement is used as an adjective, use a hyphen to connect the number to the measurement, as in 10-point type. Otherwise, don't use a hyphen.
Hyphenate a fraction written as words: Three-fifths, Four and one half.
Hyphenate a two-element number under 100: Sixty-three, twenty-one.
Don't add a hyphen before text in Rich Text Area or Long Text Area.
When alphabetizing terms, start with spaces and hyphens, followed by numbers, followed by letters. Always treat a hyphen as a space. For example:
- W2L
- Web Tab
- Web-to-Lead
- Web2Lead
Use an en dash (–) instead of a hyphen to indicate ranges, such as 1991–2010.
