Quick answer: Use everyday (one word) as an adjective to describe something ordinary or routine. Use every day (two words) as an adverbial phrase meaning “each day.” If you can replace it with “each day,” write it as two words.
This is the single most common grammatical error I see in professional emails, resumes, and published blog posts. Writers confuse the adjective everyday with the adverbial phrase every day because they sound identical when spoken aloud. However, the distinction is rigid in standard English. Getting it wrong signals a lack of attention to detail, which can undermine your credibility in job applications or client communications.
| Term | Meaning / When to use | Example sentence |
|---|---|---|
| Everyday | Adjective: Describes something commonplace, ordinary, or used daily. | These are my everyday shoes, not my formal ones. |
| Every day | Adverbial phrase: Means “each day” or “daily.” It tells you when or how often. | I go for a run every day. |
When to use everyday
Use everyday only when it functions as an adjective modifying a noun. It describes the quality of being ordinary, routine, or suitable for daily use. You will almost always find it placed directly before the noun it modifies.
Think of everyday as a synonym for “ordinary” or “standard.” If you can swap it with “ordinary” and the sentence still makes sense, you need the one-word form.
Here are three concrete examples from real-world writing scenarios where this rule applies:
- Resume/CV: “Managed everyday operational tasks for a team of ten.” (Here, everyday modifies operational tasks, describing them as routine.)
- Product Description: “This jacket is designed for everyday wear.” (It modifies wear, indicating it is for standard, daily use.)
- Email to a colleague: “Let’s stick to our everyday workflow for this project.” (It modifies workflow, describing it as the standard process.)
Note that everyday never stands alone as the subject or object of a sentence. You cannot say, “I go to the gym everyday.” That is incorrect because there is no noun for everyday to modify. In that sentence, you are describing when you go, which requires the two-word form.
When to use every day
Use every day when you mean “each day.” This is a combination of the adjective every and the noun day. Together, they function as an adverbial phrase of time. It answers the question: “How often?”
A simple test is to try replacing the phrase with “each day.” If the sentence remains grammatically correct and retains its meaning, you must use the two-word form.
Consider these examples from common communication channels:
- Text Message: “I’ll check in with you every day until the launch.” (Replace with each day: “I’ll check in with you each day…” It works.)
- Cover Letter: “I practiced coding every day for six months.” (It describes the frequency of the practice.)
- Social Media Post: “She posts a new recipe every day.” (It tells us how often she posts.)
In these instances, every day is not describing a noun; it is modifying the verb. It explains the timing or frequency of the action. the word every is a determiner that refers to all members of a set without exception, which reinforces why “every day” literally means “each individual day” in the sequence.
How to remember the difference
The most effective mnemonic I teach my editing students is the “Each Day” Swap Test.
Whenever you are unsure whether to use everyday or every day, mentally substitute the phrase “each day” into your sentence.
- If “each day” fits naturally, use every day (two words).
- If “each day” sounds awkward or changes the meaning, use everyday (one word).
Let’s apply it:
Sentence: “I drink coffee __.”
- Test: “I drink coffee each day.” (Works perfectly.)
- Result: Use every day.
Sentence: “These are my __ pants.”
- Test: “These are my each day pants.” (Sounds clunky and incorrect.)
- Result: Use everyday. (You could also test with “ordinary”: “These are my ordinary pants.” That works.)
Another visual trick is to look at the spacing. Every day has a space because it is two separate words doing two separate jobs: every specifies which days, and day is the unit of time. Everyday is squashed together because it has become a single concept—a single adjective describing normalcy.
I also recommend remembering that everyday is rarely used at the end of a sentence. Adjectives usually precede nouns. If the word in question is at the very end of your sentence, it is almost certainly every day.
- Correct: “I study Spanish every day.”
- Incorrect: “I study Spanish everyday.”
Common mistakes and exceptions
Even native speakers stumble here. Below are the most frequent errors I correct in manuscripts and how to avoid them.
The “End of Sentence” Trap
As mentioned, if the term appears at the end of a clause or sentence, it is nearly always every day.
- Wrong: “She checks her email everyday.”
- Right: “She checks her email every day.”
Why? Because there is no noun following it for everyday to modify. It is modifying the verb checks.
The “Start of Sentence” Confusion
When starting a sentence, writers often default to the one-word form because it looks more like a complete thought. Resist this urge.
- Wrong: “Everyday I wake up at 6 AM.”
- Right: “Every day I wake up at 6 AM.”
Again, apply the swap test: “Each day I wake up at 6 AM.” It works, so it must be two words.
UK vs. US Differences
There is no difference between American English and British English regarding this specific rule. Both varieties distinguish strictly between the adjective everyday and the adverbial phrase every day. You do not need to adjust your spelling based on your audience’s location. This consistency makes it easier to maintain a global brand voice without worrying about regional grammatical variations.
Compound Adjectives
A subtle exception arises when every day is part of a compound modifier before a noun, but even then, standard style guides prefer hyphenation or rephrasing rather than merging it into everyday if the meaning is strictly “each day.” However, everyday has largely absorbed the role of the adjective for “daily/routine.”
For example:
- “An everyday occurrence.” (Standard)
- “A day-to-day operation.” (Also standard, uses hyphens)
Do not write “an every-day occurrence.” While logically consistent, it is non-standard. Stick to everyday for the adjective form.
According to the entry on Everyday, the term has philosophical and sociological weight, referring to the “routine experiences” of life, which further cements its role as a descriptor of the quality of experience, not the frequency of time.
Real-World Error Fix: The LinkedIn Bio
I recently reviewed a LinkedIn bio for a marketing consultant that read:
“Helping brands grow their online presence everyday.”
This is a critical error for a professional profile. It suggests the writer does not master basic grammar. The fix is simple:
“Helping brands grow their online presence every day.”
Alternatively, if they meant to describe the type of growth, they could rephrase:
“Driving everyday growth for brands through strategic content.”
But in the original context, they were describing when they help brands grow (continuously), so every day was the required form.
Frequently Asked Questions
Can I use everyday as a noun? No. Everyday is strictly an adjective. You cannot say, “This is part of my everyday.” You must say, “This is part of my everyday life” or “This is part of my daily routine.”
Is it okay to use everyday in informal texting? While people may understand you, it is still grammatically incorrect. In professional contexts, even casual ones like Slack or Teams, using the correct form demonstrates precision. I recommend always using every day when you mean “each day,” regardless of the platform.
What is the difference between daily and everyday? Daily is an adjective or adverb that strictly means “occurring once a day” or “for each day.” Everyday is an adjective that means “ordinary” or “commonplace.” For example, “a daily newspaper” (published each day) vs. “everyday news” (ordinary, non-sensational news). They overlap but are not interchangeable.
Why do spellcheckers sometimes miss this error? Spellcheckers verify if a word exists in the dictionary. Since everyday is a valid word, the software assumes you intended to use the adjective. It cannot determine from context whether you meant the adjective everyday or the adverbial phrase every day. You must rely on the “each day” swap test to catch this error.
