Three letter acronym

From Wikipedia, the free encyclopedia

A three letter acronym (commonly referred to as a TLA) is an abbreviation, an alphabetism, an initialism or an acronym consisting of three letters.

Many of the abbreviations described as "three letter acronyms" are initialisms, which some definitions of acronym do not include (See acronym and initialism). Nevertheless, "Three letter acronym" is commonly used for any set of three letters used as an abbreviation.

[edit] History and origins

The first known use of the term "TLA" was by Texas Instruments Inc. employees in the Industrial Systems Division circa 1984. Engineers used to mock the marketing department's tendency to define new products with three-word descriptions, such as "CVU" for a product line called "Control Vision Unit" and "ACM" for "Automation Configuration Module." Due to the seemingly excessive use of three-letter abbreviations or initialisms at the company, the employees started to simply report that they were working on product "TLA" as an ironic self-reference.

Use of "TLA" spread through both industry and academia, and now has become a generally understood initialism.^[1] For a complete discussion of the various forms of abbreviations, acronyms and other letter substitutions, see Acronym and initialism.

[edit] Other information

• Another use of TLA is "three-letter agency", referring to a law enforcement or intelligence agency with a three-letter name abbreviation, such as the Federal Bureau of Investigation, the Central Intelligence Agency, and the National Security Agency.
• The number of possible three-letter abbreviations using the 26 letters of the alphabet from A to Z ( AAA, AAB ... to ZZY, ZZZ) is 26 × 26 × 26 = 17,576. An exhaustive listing of TLAs can be found in Category:Lists of TLAs.
• In English, WWW is the longest possible TLA to pronounce, requiring nine syllables. Although in written English it is an abbreviation, in spoken English it may use more syllables than that which it is abbreviating.^[2] There is more information at Pronunciation of "www".
