I actually can&#x27;t find a source. My professor told me back in the day, and that&#x27;s all I have.<p>The talk page on Wikipedia has a lot of discussion, including a citation of a book, but I don&#x27;t have the book: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Talk%3ASQL#SQL_Acronym" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Talk%3ASQL#SQL_Acronym</a><p>Someone there  also keeps saying that the second reference on the article explicitly says it&#x27;s not an acronym, but the current second source explicitly says it is, so... ¯\_(ツ)_&#x2F;¯
