It’s too bad this word didn’t stick. A note I read was like, “Oh, this is a word Shakespeare made up. Ha, ha. Hamlet’s fooling Osric with a made up word!”
But Shakespeare made up words all the time and not just when he wanted to make fun of a pompous talker. Some of them really caught on.
So I’m sorry this one didn’t. I mean – really – just straight up “concern” would get the job done. The “ancy” is extra. But it does add something. It feels like not just the concern – but the whole concern situation, the whole cluster of things around a concern. A concernancy. Also – it’s so easy to work out what it is – even though it’s not a word that any of us know.
