The word "yahoo" is a backronym for "Yet Another Hierarchically Organized Oracle"{{cite news |work=Network World |title=Hello, Is Anyone Out There? |url=https://books.google.com/books?id=pw4EAAAAMBAJ&pg=RA1-PA40 |date=September 11, 1995 |last=Gaffin |first=Adam |access-date=March 5, 2015 |archive-date=May 14, 2015 |archive-url=https://web.archive.org/web/20150514163028/https://books.google.com/books?id=pw4EAAAAMBAJ&pg=RA1-PA40 |url-status=live }} or "Yet Another Hierarchical Officious Oracle".{{cite news | url=https://www.lifewire.com/what-does-yahoo-stand-for-2483337 | title=What Does "Yahoo" Stand For? | first=Paul | last=Gil | work=Lifewire | date=April 19, 2021 | access-date=May 4, 2021 | archive-date=October 7, 2016 | archive-url=https://web.archive.org/web/20161007112246/http://netforbeginners.about.com/od/internet101/f/yahoostory.htm | url-status=live }} The term "hierarchical" described how the Yahoo database was arranged in layers of subcategories. The term "oracle" was intended to mean "source of truth and wisdom", and the term "officious", rather than being related to the word's normal meaning, described the many office workers who would use the Yahoo database while surfing from work.{{cite web |title=What Does 'Yahoo' Stand For? |url=http://netforbeginners.about.com/od/internet101/f/yahoostory.htm |last=Gurnitsky |first=Joanna |work=About.com |access-date=July 2, 2012 |url-status=live |archive-url=https://web.archive.org/web/20120411035134/http://netforbeginners.about.com/od/internet101/f/yahoostory.htm |archive-date=April 11, 2012}} However, founders Filo and Yang insist they mainly selected the name because they liked the slang definition of a "yahoo" (used by college students in David Filo's native Louisiana in the late 1980s and early 1990s to refer to an unsophisticated, rural Southerner): "rude, unsophisticated, uncouth."{{cite web|url=http://docs.yahoo.com//info//misc//history.html|title=The History of Yahoo! – How It All Started ... |date=January 9, 2011 |publisher=Yahoo |archive-url=https://web.archive.org/web/20110109042907/http://docs.yahoo.com//info//misc//history.html|archive-date=January 9, 2011}} This meaning derives from the Yahoo race of fictional beings from Gulliver's Travels.
