I have what is probably a stupid question but what is the difference between an Elseworlds and AU story?
Not a stupid question at all! This is actually an excellent question because it's something unique to this fandom and probably a lot of people don't know this.
Because this show features an established, canon Alternate Universe, we use that term to refer to stories about the "Alt-Clark" (and his Lois) featured in the episodes Tempus Anyone and Lois and Clarks. All other stories about original universes created by the author (what would be called AUs in other fandoms) are Elseworlds.
