Randomly found somewhere that "non-plussed" also exists...

I tried looking up "non-plussed" in a dictionary (a long time ago. in one of the old paper ones) and it didn't exist. I was starting to think it was a Sir-Pterry-ism, but apparently not.

I now refuse to feel guilty or illiterate (despite some people's arguments, who shall not be named) about using the word 'non-plussed', but as far as I'm concerned, it's something created by Sir Pterry, and I will not be taking criticism! 😹❤️
