Dear People of the English-Speaking World:
The word is "normality".
Think about "formal", which is an adjective. Now make it into a noun....did you say to yourself, "formalcy"? No, you did not.
There is no such word as "normalcy". You may have used it yourself, and now you're saying "What? Of course there is!" But don't feel badly; you couldn't have known. It's everywhere - like "impact" used as a verb, as in "Your hydro bill won't really be impacted by that." [im-PAC-ted...yuck] When, really, if you're not talking about a wisdom tooth or a bowel, don't say "impacted".
You could say "These changes won't really have an impact on your hydro bill."
Is "normalcy" in the dictionary? Sure. So is "LOL", and you won't catch etymologists and grammarians using that, either.
So please practice this: "The English language has to regain some semblance of normality."
You are a person with free will - of course you are. And if you decide to say "The English language has to regain some semblance of normalcy," nobody will arrest you. You just won't have my blessing, that's all.
And really, who cares about that?
