Yes, “everyday” is two separate words, despite the way it appears to be spelled on most social media platforms. The rule of thumb for determining whether a word is one or two words is to determine whether it can stand alone as a complete sentence. If the word can stand on its own, then it is a single word. For example, “I eat breakfast every day” is one word because you could say “I eat breakfast” and mean either breakfast food in general or the morning meal. However, if you wrote “I eat brekkfast every day” then both terms would need to appear together for the phrase to be one word.
