Here's your sign! I always pay attention to signs as I drive. This morning as I drove along one of the main thoroughfares in town, I saw the following sign posted outside a well-known local business: "We start fresh everyday." Is this sign grammatically correct?
If you answered "yes," you're incorrect. The sign should say, "We start fresh every day."
"Every day" means each day.
Example:
I eat Cheerios every day for breakfast. (each day)
She had a migraine every day for a month. (each day)
However, "everyday," not "every day," is used as an adjective. "Everyday" can also be used as a noun when it means routine or ordinary day or occasion.
Example:
Biting his fingernails was an everyday occurrence. (adjective)
We use linen napkins at dinner when company is invited; otherwise, we use paper napkins for everyday. (noun meaning an ordinary day)
I hope the blog above helps my fellow writers understand the everyday use of "every day" and "everyday" every day they use it.
