YSK: 'every day' and 'everyday' are different words
Why ysk? Because a shocking number of people use everyday for all forms. They're different words with different meanings. I see it absolutely everywhere.
Everyday is an adjective (describing word, like skinny, muscly, cold). It means ordinary, typical or usual. E.g. jeans are a type of everyday fashion.
You would go to the gym every day, not everyday.
But going to the gym could be an *everyday* (typical) thing. #education
