UKRA = United Kingdom Reading Association
Compounds formed with the prefix under- are normally closed (CMS 15th, 7.90):
underdeveloped, underprivileged, underrepresented, underway
UNESCO = United Nations Educational, Scientific and Cultural Organization
UNICEF = United Nations Children’s Fund
Uniform Resource Locator = URL
uninterrupted sustained silent reading = USSR
unique, more or less, very, or somewhat
The literal meaning of unique is “one of a kind”; therefore, it makes little sense to describe one thing as “more unique” than another, or “most unique” among a group of things. Likewise, any attempt to enhance or strengthen the uniqueness of an object (“very unique”) will be redundant (See absolute adjectives).
United Kingdom Reading Association = UKRA
United Nations Educational, Scientific and Cultural Organization = UNESCO
United Nations Children’s Fund = UNICEF
Capitalize only as part of the name of an institution: the Ohio State University, the University of Southern California. Otherwise lowercase: a university, the university

up-to-date (adjective preceding noun)
URL = Uniform Resource Locator (plural is URLs)
- Effective July 1, 2007, IRA books and journals will no longer include "http://" when URLs appear in text or reference lists.
- Editors of other IRA documents may choose to include "http://" in URLs or to exclude it, but they should follow a consistent pattern in doing so (e.g., leave out the "http://" for URLs that begin with "www.," but include it for those that do not).
- URLs that appear in print should not be underscored.
- Where it is necessary to break a URL or an e-mail address, no hyphen should be used. The break should be made between elements, after a colon, a slash, a double slash, or the symbol @ but before a period or any other punctuation or symbols. To avoid confusion, a URL that contains a hyphen should never be broken at the hyphen. If a particularly long element must be broken to avoid a seriously loose line, it should be broken between syllables. (See CMS 15th 7.44.)
US / U.S., USA / U.S.A.
- CMS 15th, 15.34 allows use of U.S. as a noun in tabular or tightly-set material (otherwise, spell out United States). CMS 15th, 15.34 allows U.S. as an adjective in all but the most formal texts.
- The abbreviation US (without periods) is used before a dollar sign to indicate U.S. currency. Thus, “The subscription price of the new publication is US$72.50 per year.” (See CMS 15th, 9.24)
- The abbreviation USA (without periods) is used in addresses, where it follows zip code and comma: “Newark, DE 19714-8139, USA,” and is used in affiliations within running text: "Author teaches at Smallville High School, Smallville, Illinois, USA." [Note that the state name is spelled out in running text.]
