There have been so many places in front end web dev that used the abbreviation “a11y” without defining it (or explaining the 11) that for years I assumed it was just the name of a particular library that had gotten Kleenexed.

(To be clear, I’m using “Kleenexed” as a verb here to mean “genericized explosively, as if a sneeze.”)

It didn’t help to look at the code, either. “Okay cool, so all this does is add a bunch of random extra tags to the DOM? Doesn’t seem super useful but okay, I guess there’s probably some tool out there that depends on them but we probably don’t use it.”

I've always followed a rule of which was popular first claims it. TF2 is Team Fortress 2, not Titanfall 2, DS2 is Dark Souls 2 not Death Stranding 2 etc etc.

If you gonna abbreviate, say its name in full first in the context, otherwise I'll assume another!
