use the proper grammar. it's "every day" not "everyday"
Incorrect, both are acceptable and are used differently/interchangeable in context.
In this context Everyday is acceptable as one word.
No need to degrade a post when it is correct.
Quote:
Everyday is an adjective used to describe things that (1) occur every day, or (2) are ordinary or commonplace. In the two-word phrase every day, the adjective every modifies the noun day, and the phrase usually functions adverbially. For example, every day you eat breakfast. You brush your teeth every day. Maybe you go for a walk every day. These are everyday activities.
