Over the last few months, I’ve heard a slew of smart, literate people use ‘nonplussed’ to mean ‘unfazed’ or ‘unimpressed’.

Unfortunately, that’s not what the word means.

Instead, ‘nonplussed’ means ‘bewildered’ or ‘confused’.

I’m totally nonplussed as to why nobody can use that shit correctly.

[Bonus fact: similarly, ‘ambivalent’ doesn’t mean ‘I don’t care’. Instead, it means pretty much the exact opposite: ‘I’m torn between strong opposing feelings about this.’ Get that one right, too.]
