Hi, English isn’t my mother tongue so I was asking myself that question since I first encounted a w/… Back then I was like: “What tf does ‘w slash’ stand for?” And when I found out I was like “How, why, and is it any intuitive?” But I never dared to ask that until now
I think it’s usually the first letter(s) and the last letter(s). In older English handwritings I’ve come across M.ʳ etc. So I think that’s were those came from.
In the Speedwriting shorthand system, developed in 1924 for use with typewriter, / Is used to denote omitted sylables, so ‘with’ becomes w/ and ‘without’ becomes w/o. Here is a pretty deep guide on the precepts of Speedwriting:

But shouldn’t “w/o” then be written as “w/o/”?
And “N/A” omits more than one sylable in “applicable”.
I guess it’s a grown system.
Yeah. I have no evidence that this system invented those shortcuts, they may predate it by quite a bit
Yeah, it’s really hard to pinpoint such simple inventions.
