NATO: North Atlantic Treaty Organization.Pronounced as a word, containing only initial letters.The spelled-out form of an acronym or initialism (that is, what it stands for) is called its expansion. For example, the terms URL and IRA can be pronounced as individual letters: / ˌ juː ˌ ɑːr ˈ ɛ l/ and / ˌ aɪ ˌ ɑːr ˈ eɪ/, respectively or as a single word: / ˈ ɜːr l/ and / ˈ aɪər ə/, respectively. There is also some disagreement as to what to call abbreviations that some speakers pronounce as letters and others pronounce as a word. There is no rule on what to call abbreviations whose pronunciation involves the combination of letter names and words, such as JPEG / ˈ dʒ eɪ p ɛ ɡ/ and MS-DOS / ˌ ɛ m ɛ s ˈ d ɒ s/. The rest of this article uses acronym for both types of abbreviation. Examples in reference works that make the distinction include NATO / ˈ n eɪ t oʊ/, scuba / ˈ s k uː b ə/, and radar / ˈ r eɪ d ɑːr/ for acronyms, and FBI / ˌ ɛ f ˌ b iː ˈ aɪ/, CRT / ˌ ˈ s iː ˌ ɑːr ˌ t iː/, and HTML / ˌ eɪ tʃ ˌ t iː ˌ ɛ m ˈ ɛ l/ for initialisms. The distinction, when made, hinges on whether the abbreviation is pronounced as a word or as a string of individual letters. Some dictionaries include additional senses equating acronym with initialism. Īlthough the word acronym is often used to refer to any abbreviation formed from initial letters, many dictionaries and usage commentators define acronym to mean an abbreviation that is pronounced as a word, in contradistinction to an initialism (or alphabetism)-an abbreviation formed from a string of initials (and possibly pronounced as individual letters). Attestations for Akronym in German are known from 1921, and for acronym in English from 1940. Whereas an abbreviation may be any type of shortened form, such as words with the middle omitted (for example, Rd for road or Dr for Doctor), an acronym is a word formed from the first letter or first few letters of each word in a phrase (such as sonar, created from sound navigation and ranging). 5.2 Redundant acronyms and RAS syndrome.5 Changes to (or word play on) the expanded meaning.
