This is an interesting article on the use of “slash” as a conjunction slash topic shift marker, a use which is definitely part of my idiolect. (There is also, of course, slash as in slashfic, but that’s an entirely different usage.)
Anne Curzan, the author, identifies approximately four main uses of “slash”, so I decided to search my own email corpus for examples, to add to the citable set of data on slash, and also to see how long I’ve been using it. So below is the earliest example I can find for each.
1. Slash meaning “or”, “and”, or “and/or”.
