'Everyday' vs. 'Every Day'
What to Know
Compound words like everyday, sometimes, and anytime can be confusing in usage and spelling: Do you go to work every day or everyday? Do you drink tea in the afternoon or after noon? Often, the rule is that the closed versions of words function as adverbs ("come see us sometime") or adjectives ("an everyday occurrence"), while the words that appear separately or open are generally used as nouns ("this might take some time," "I’ll see if I can find any more"). There are exceptions to this rule, as some compounds function both as nouns and adjectives and others have different meanings when closed vs. open (superhero and super hero).
We all make decisions about which words to use when we write every day.
In fact, you might call them everyday decisions.
It’s one of the maddening complexities of English that we easily agree to make compound words—words composed of other words mashed together—but we don’t agree on easy or even consistent guidelines for doing so: sometimes we write this sometime adjective, when it’s used as a noun that expresses duration, as some time. Or we might write “Call me anytime” at any time. And have afternoon tea, but only if it’s actually after noon.
How to Use Most Compound Words
There is, however, a hint of a method to this spelling madness. In cases like these, when words that seem to have competing forms appear sometimes closed or sometimes separately, the closed versions (those written as a single word) are words that describe or modify other words:
Come see us sometime. ADVERB
He was a sometime actor. ADJECTIVE
Call again anytime. ADVERB
I never go there anymore. ADVERB
An everyday occurrence. ADJECTIVE
When the constituent words appear separately, these terms are nouns that are modified by the words that precede them (like some, any, or every).
This might take some time. NOUN
They might arrive at any time. NOUN
I’ll see if I can find any more. NOUN
Every day I have the blues. NOUN
Exceptions to the Rule
This is pretty straightforward. Except, of course, for the exceptions (this being English).
And anywhere is written in the same form, whether as an adverb (“Go anywhere you like”) or as a noun (“Easy to find from anywhere”).
Then, of course, there are compound nouns that have different meanings when closed or open. After all, a superhero is often different from a super hero. Underpants still should be worn under pants.
There’s even a sneaky category of words that behave like adjectives in some situations, like afternoon (as in “an afternoon nap”), even though they are technically nouns. When used this way, these nouns are called attributive, because we never say afternoonest or claim that one hour is “more afternoon” than another.
So, despite the sometimes confusing pairings of altogether different words that are nevertheless spelled with the same letters, the simplest advice is: avoid confusing these everyday words every single day.
