Some would call them acronyms, which sticklers would challenge.<\/p>\n<p><strong>Acronyms<\/strong> are abbreviations that are pronounced as words by using primary starting letters of the words in the abbreviated phrase.<br \/>\n<strong>Examples:<\/strong><br \/>\n&#8211; NATO (North Atlantic Treaty Organization)<br \/>\n&#8211; AIDS (Acquired Immune Deficiency Syndrome)<br \/>\n&#8211; OPEC (Organization of the Petroleum Exporting Countries)<br \/>\n&#8211; SPA (Society of Professional Accountants)<br \/>\n&#8211; ASAP (as soon as possible)<br \/>\n&#8211; Radar (radio detecting and ranging)<br \/>\n&#8211; Scuba (self-contained underwater breathing apparatus)<\/p>\n<p>Do you ever wonder about the origin of a word or when it came to be a common part of the language? According to Ask.com, the word <em>acronym<\/em> originated in 1943: \u201cAs wartime production of names using initials reached an all-time high, it was high time to give a name to the growing arsenal of alphabetic abbreviations. That need was met in a note in the February 1943 issue of <em>American Notes and Queries<\/em>: &#8216;Your correspondent who asks about words made up of the initial letters or syllables of other words may be interested in knowing that I have seen such words called by the name <em>acronym<\/em>, which is useful, and clear to anyone who knows a little Greek.&#8217; &#8221;<\/p>\n<p>\u201cGreek?&#8221; Yes, <em>acronym<\/em> follows the model of other designations for types of words, such as <em>synonym, antonym, and homonym<\/em>. The <em>-nym<\/em> means &#8220;a kind of word&#8221;; <em>acro-<\/em> means &#8220;top, peak, or initial,&#8221; as in <em>acrobat<\/em> or <em>acrophobia<\/em>.<\/p>\n<p>In step with our observation about differences among dictionaries and style manuals, the <em>Oxford English Dictionary<\/em> offers two definitions of &#8220;acronym&#8221;:<\/p>\n<ol>\n<li>A group of initial letters used as an abbreviation for a name or expression, each letter or part being pronounced separately; an initialism (such as\u00a0<em>ATM<\/em>,\u00a0<em>TLS<\/em>). (earliest citation of use 1940)<\/li>\n<li>A word formed from the initial letters of other words or (occasionally) from the initial parts of syllables taken from other words, the whole being pronounced as a single word (such as\u00a0<em>NATO<\/em>,\u00a0<em>RADA<\/em>). (earliest citation of use 1943)<\/li>\n<\/ol>\n<p>As the two diverging definitions suggest, even leading language authorities are not resolute on the subject. While you may continue to come across such variances for <em>acronym\u00a0<\/em>and\u00a0<em>initialism,<\/em> you can aim for precision within your own understanding and use by applying the differentiations that we&#8217;ve discussed.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dictionaries don\u2019t all agree on the definitions of these words and neither do style manuals.
