A three-letter acronym (TLA), or three-letter abbreviation, is as the phrase suggests an abbreviation consisting of three letters. The abbreviation for TLA, TLA, has a special status among abbreviations and to some is humorous since abbreviations that are three-letters long are very common and TLA is, in fact, a TLA.
TLA is autological.
Most TLAs are initialisms (the initial letter of each word of a phrase), but most are not acronyms in the strict sense since they are pronounced by saying each letter, as in APA /ˌeɪpiːˈeɪ/ AY-pee-AY. Some are true acronyms (pronounced as a word) such as CAT (as in CAT scan) which is pronounced as the animal.
The exact phrase three-letter acronym appeared in the sociology literature in 1975. [1] Three-letter acronyms were used as mnemonics in biological sciences, from 1977 [2] and their practical advantage was promoted by Weber in 1982. [3] They are used in many other fields, but the term TLA is particularly associated with computing. [4] In 1980, the manual for the Sinclair ZX81 home computer used and explained TLA. [5] The specific generation of three-letter acronyms in computing was mentioned in a JPL report of 1982. [6] In 1988, in a paper titled "On the Cruelty of Really Teaching Computing Science", eminent computer scientist Edsger W. Dijkstra wrote (disparagingly), "No endeavour is respectable these days without a TLA" [7] By 1992 it was in a Microsoft handbook. [8]
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. Allowing a single digit 0-9 increases this by 26 × 26 × 10 = 6,760 for each position, such as 2FA, P2P, or WW2, giving a total of 37,856 such three-character strings.
Out of the 17,576 possible TLAs that can be created using 3 uppercase letters, at least 94% of them had been used at least once in a dataset of 18 million scientific article abstracts. Three-letter acronyms are the most common type of acronym in scientific research papers, with acronyms of length 3 being twice as common as those of length 2 or 4. [9]
In standard English, WWW is the TLA whose pronunciation requires the most syllables—typically nine. The usefulness of a TLA typically comes from its being quicker to say than the phrase it represents; however saying 'WWW' in English requires three times as many syllables as the phrase it is meant to abbreviate (World Wide Web). "WWW" is sometimes abbreviated to "dubdubdub" in speech. [10]

Camel case is the practice of writing phrases without spaces or punctuation and with capitalized words. The format indicates the first word starting with either case, then the following words having an initial uppercase letter. Common examples include YouTube, PowerPoint, HarperCollins, FedEx, iPhone, eBay, and LaGuardia. Camel case is often used as a naming convention in computer programming. It is also sometimes used in online usernames such as JohnSmith, and to make multi-word domain names more legible, for example in promoting EasyWidgetCompany.com. In fact, WikiWikiWeb, an ancestor of Wikipedia, is written in camel case.
Leet, also known as eleet or leetspeak, or simply hacker speech, is a system of modified spellings used primarily on the Internet. It often uses character replacements in ways that play on the similarity of their glyphs via reflection or other resemblance. Additionally, it modifies certain words on the basis of a system of suffixes and alternative meanings. There are many dialects or linguistic varieties in different online communities.
The ZX81 is a home computer that was produced by Sinclair Research and manufactured in Dundee, Scotland, by Timex Corporation. It was launched in the United Kingdom in March 1981 as the successor to Sinclair's ZX80 and designed to be a low-cost introduction to home computing for the general public. It was hugely successful; more than 1.5 million units were sold. In the United States it was initially sold as the ZX-81 under licence by Timex. Timex later produced its own versions of the ZX81: the Timex Sinclair 1000 and Timex Sinclair 1500. Unauthorized ZX81 clones were produced in several countries.
Thorn or þorn is a letter in the Old English, Old Norse, Old Swedish and modern Icelandic alphabets, as well as modern transliterations of the Gothic alphabet, Middle Scots, and some dialects of Middle English. It was also used in medieval Scandinavia but was later replaced with the digraph th, except in Iceland, where it survives. The letter originated from the rune ᚦ in the Elder Futhark and was called thorn in the Anglo-Saxon and thorn or thurs in the Scandinavian rune poems. It is similar in appearance to the archaic Greek letter sho (ϸ), although the two are historically unrelated. The only language in which þ is currently in use is Icelandic.
