Maybe it's just me, but I am seeing a whole lot of people using "weary" when they mean "wary" in online communications. Social media and so-called "more professional" situations like internal Slack, presentations, in-house reports and documents, etc.
Am I just waving an old-person flag and this is a cool thing the kids are doing these days? Maybe a widely-used autocorrect facility is tripping them up? Or is this another example of language shifting in unexpected ways?
