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
Just wait until you encounter morse code abbreviations, some of which are still used in some industries. Like the wonderful X abbreviations, such as:
Wx - weather
Mx - maintainence
Tx/Rx - transmit/receive
Edit: I’m starting to think every industry totally did their own thing with morse abbreviations
Hx, Rx, Tx are history, prescription and treatment in medical jargon
Cx - customer is one I run into daily.
I work in radio electronics. I use these, too.
Lol those are wild
