You refer to the wikipedia page on SQL[^] and claim that the official pronunciation is Sequel. However I read on the wikipedia page the following: SQL (officially pronounced /ˌɛskjuːˈɛl/ like "S-Q-L" but often pronounced /ˈsiːkwəl/ like "sequel") The revision history shows why. :-D In the last 2 days anonymous editors tried to get "sequel" to be the official pronunciation but the wikipedia moderators overruled them :)
