Gopher writes, “I get everyday and every day mixed up, but I’m pretty sure this one is whack.”
Gopher is right. They are making a complicated play on words but it doesn’t actually work. This is one idea that should have stayed on the drawing board.
Okay, here’s the deal. Everyday is an adjective, it means ordinary or commonplace (quotidian, if you will). In the phrase every day, every is an adjective that modifies day. Good explanation here.
In this case, I suspect they are making a play on someday and the meaning of everyday.
But they shouldn’t feel bad. People make this mistake every day.
