Everyday (one word) is an adjective meaning ordinary, common, or routine, and it almost always sits in front of a noun: everyday clothes, an everyday problem. Every day (two words) is a phrase meaning each day, and it usually tells you how often something happens: I check my email every day. If you can replace the words with "each day" — or slip "single" into the middle to get "every single day" — you want the two-word version.
The single word everyday is an adjective. It describes something normal, unremarkable, or used as a matter of routine — the opposite of special or occasional. Because it is an adjective, it normally comes directly before the noun it describes.
Synonyms that prove you want one word: ordinary, common, routine, run-of-the-mill, day-to-day. If one of those could stand in the sentence, everyday is correct. The word can also act as a noun in the set phrase "the everyday," meaning ordinary daily life: photography that celebrates the everyday. That noun use is deliberate and slightly literary.
Split into two words, every day is the determiner every modifying the noun day. It means each day and most often works as an adverbial, telling you how frequently something happens. It can also open a sentence as a noun phrase.
In every one of these you could say "each day" without changing the meaning — the surest sign you need the space.

By far the most common mistake is the first kind: writing the single word everyday when you mean "each day." When in doubt, pull the two words apart and try "each day."
A noun after the phrase does not automatically make it one word. In I swim every day of the week, "day" is still a plain noun and the phrase stays split — "each day of the week" proves it.
Informally, everyday sometimes appears after a linking verb to mean "unremarkable": The hotel room felt a bit everyday. This is fine in casual writing, but in formal prose ordinary reads better.
Watch out for brand names, song titles, and slogans that style Everyday as one word for effect — Buddy Holly's "Everyday," Walmart's "everyday low prices." Marketing choices are not grammar rules; judge your own sentence on its meaning.
The same closed-vs-open logic governs several look-alike pairs: anytime / any time, someday / some day, and sometime / some time. The joined form is a general adverb; the split form counts a specific unit. When you mean a measurable amount — "any time to spare," "some day next week" — keep the space.
Finally, the two are stressed differently when spoken. The adjective is said with the stress up front — EV-eryday — while the phrase leans on the end — every DAY. Reading a sentence aloud can settle which one you mean.
Picture the gap. Every day has a space in the middle that is wide enough to drop single into, turning it into every single day. If that gap can be filled, keep the two words. The closed-up everyday has no room for anything extra, because it is one plain, ordinary word — and "ordinary" is exactly what it means.
No — this is one rule that holds on both sides of the Atlantic. American and British style guides, and dictionaries from Merriam-Webster to Oxford, all treat everyday as the ordinary-adjective and every day as the "each day" phrase in exactly the same way. The spelling, the hyphen-free form, and the meaning are identical in US and UK English, so you can apply the tests above with confidence wherever you write.
It depends on meaning. Use everyday (one word) as an adjective for something ordinary or routine before a noun: everyday clothes. Use every day (two words) when you mean each day: I run every day. Quick test — if 'each day' fits the sentence, use two words; if 'ordinary' fits, use one.
No. There you mean 'each day,' which is an adverb phrase, so it must be two words: I use it every day. The single word everyday is an adjective for ordinary things, as in 'everyday use.' A reliable check: if you can say 'every single day,' write two words.
Everyday (one word) is an adjective meaning ordinary, common, or routine — the opposite of special. It describes a noun: everyday clothes, everyday chores, an everyday event. Think 'run-of-the-mill.' It does not mean 'each day'; for that sense you need the two-word phrase every day, as in 'I train every day.'
The two-word form every day is not the adjective split apart — it is a different structure meaning 'each day' (the determiner every plus the noun day). So you never break the ordinary-adjective into two words. Write everyday for ordinary, and every day only when you mean each day.
They overlap but aren't identical. Everyday is only an adjective meaning ordinary: everyday tasks. Daily works as both an adjective and an adverb and stresses frequency — happening each day: a daily walk, or I walk daily. Use everyday for 'ordinary,' and daily or every day when you mean 'each day.'
