The Latin et cetera, abbreviated etc., is often used at the end of an incomplete, inclusive list of items when it is clear that there are more items than can be enumerated conveniently and there is no ambiguity about what the omitted items are. For example: "Joseph's amazing technicolor dreamcoat was red, yellow, green, brown, scarlet, etc."
Is there an equivalent abbreviation that would serve a similar purpose when the list is exclusive? "My mother hit your mother in the nose. What color blood came out? Was it red, yellow, green, brown, scarlet, ...?"
I have always just rewritten the sentence or written out the full "or something else," but the lack of complementary abbreviation to etc. has always bothered me.
