Everyday and every day are commonly confused in English. There’s no difference in pronunciation, but using the wrong one when writing is a mistake in the everyday English you use every day.
Everyday is an adjective that means commonplace, ordinary, or normal.
Every day means "each day."
The Bottom Line
Everyday is a single word and is an adjective, so it’s the one that is used in front of a noun to describe something as normal or commonplace. Every day is an adjective (every) plus a noun (day), and it means each day.
