Dictionary (Mario's Time Machine)
From the Super Mario Wiki
The Dictionary is an item in the PC release of Mario's Time Machine. It is a book written, compiled, and published by Noah Webster. Mario receives it from the official speechwriter for president Abraham Lincoln after he travels back in time to the White House in Washington, D.C. circa 1863. In their conversation, the speechwriter brings up Lincoln's Emancipation Proclamation, and Mario does not know what either of those words means. The speechwriter then explains the words to Mario and also gives him his Dictionary, which he personally used to check over the Proclamation. Mario then gives the Dictionary to Frederick Douglass after Mario asks him what an abolitionist is, and Frederick tells him to bring a dictionary so that he may be properly educated. Once Frederick has the Dictionary, he tells Mario to immediately look up the words "abolition," "prejudice," and "emancipation," while also mentioning that Mario is very eager to learn.
