Etymology
Origin of official
First recorded in 1300–50; Middle English, from Late Latin officiālis “of duty,” equivalent to Latin offici(um) “service, duty” + -ālis adjective suffix; see origin at office, -al 1
Explanation
Official is the real deal. If you want the latest news from Graceland, check the official Elvis Presley website. But you’ll have to look elsewhere to find the unofficial, unapproved, and highly unlikely scoop on Elvis sightings. If something is official, it's authorized and approved by somebody. If Gatorade is the official drink of the Olympics, somebody with authority has signed some papers and a deal has been made. When you're playing soccer or other sports, the official is the person who makes the calls; he referees (or officiates) the game.
