Definition and Examples of RAS Syndrome

RAS syndrome is a humorous initialism for Redundant Acronym [or Abbreviation] Syndrome syndrome: the (redundant) use of a word thats already included in an acronym or initialism. Also known as  PNS syndrome (PIN number syndrome syndrome) and acronym-assisted pleonasm. Common examples of RAS syndrome include  PIN number (personal identification number number),  AC current (alternating current current) and HIV virus (human immunodeficiency virus virus).  Such redundancies, says Bryan Garner, may be passable in speech—especially with unfamiliar acronyms—[but] they should be avoided in formal writing (Garners Modern American Usage, 2009). The term RAS syndrome first appeared in the magazine New Scientist (May 26, 2001).
