All and every are both correct standard English words, and both can express complete coverage. However, they do not follow the same grammatical patterns.
Compare:
“All students received a certificate.”
“Every student received a certificate.”
Both sentences can describe the same overall result, but the structure differs.
All commonly presents a complete group, amount, or extent as a total.
Every refers exhaustively to individual members, normally through a singular count noun.
Compare another pair:
“All the doors were locked.”
“Every door was locked.”
The meanings overlap, but the words are not freely interchangeable.
Quick Answer
Use all for a complete group or amount, especially with plural and uncountable nouns:
“All employees are required to attend.”
“All information is confidential.”
Use every for each member without exception, normally before a singular count noun:
“Every employee is required to attend.”
“Every answer was correct.”
A useful pattern is: all + plural/uncountable noun; every + singular count noun.
Why People Confuse Them
The two words are confusing because they can both refer to 100% of a relevant group.
Compare:
“All guests arrived on time.”
“Every guest arrived on time.”
Both mean that no guest was absent.
Similarly:
“All the rooms were clean.”
“Every room was clean.”
The factual result is almost identical.
The difference becomes clearer when we look at grammar:
“all students”
“every student”
“all the students”
“every one of the students”
Learners sometimes assume that because the meanings overlap, the words can be swapped directly. That leads to errors such as:
“Every students…”
or:
“Every of them…”
Equivalent reference does not mean identical sentence structure.
Key Differences At A Glance
| Feature | All | Every |
|---|---|---|
| Core idea | Complete group, amount, or extent | Each member without exception |
| Typical count noun | Plural | Singular |
| Uncountable noun | Yes | Normally no |
| Verb agreement | Depends on noun/reference | Normally singular |
| Before the/my/these | Yes: all the, all my | Not directly |
| With “of them” | all of them | every one of them |
| Time meaning | Complete duration: all day | Recurrence: every day |
| Intervals | Less typical | Very common: every three days |
| Standalone use | Possible | Bare every normally cannot stand alone |
| Fully interchangeable | No | No |
Examples:
“all books”
“every book”
“all water”
“every bottle of water”
“all my friends”
“every friend”
“all of us”
“every one of us”
Meaning and Usage Difference
All: The Complete Group or Amount
Use all when referring to the complete number, amount, extent, or group.
With plural count nouns:
“All children need support.”
“All employees received an email.”
“All the books were damaged.”
With uncountable nouns:
“All information is confidential.”
“She used all the flour.”
“We spent all our money.”
All Before Another Determiner
All can come before words such as the, my, these, or a number:
“all the students”
“all my coworkers”
“all these files”
“all five reports”
This is an important structural difference from every.
Every: Each Member Without Exception
Use every when referring to all members individually and exhaustively.
“Every child needs support.”
“Every employee received an email.”
“Every book was damaged.”
The noun after every is normally singular.
Correct:
“Every student passed.”
Incorrect:
“Every students passed.”
Similar Meaning, Different Perspective
Compare:
“All students passed.”
“Every student passed.”
Both mean that 100% of the students passed.
The first presents the students as the complete group.
The second distributes the statement across each individual student.
The truth of the situation may be the same even though the grammatical perspective differs.
Uncountable Nouns
Use all directly with uncountable nouns:
“All the information is accurate.”
“All the equipment was inspected.”
Do not normally use every directly:
Incorrect:
“Every information is accurate.”
Use a countable unit:
“Every piece of information is accurate.”
Time: Duration Versus Recurrence
Compare:
“We worked all day.”
This means throughout the complete day.
“We work every day.”
This means on each day repeatedly.
Similarly:
“all week” = throughout the whole week
“every week” = once or repeatedly each week
Every and Intervals
Every is natural for regular intervals:
“The medication is taken every six hours.”
“The bus arrives every 20 minutes.”
“We meet every three weeks.”
This is an important exception to the simple rule that every is always followed immediately by a singular noun.
All of and Every One of
Use:
“All of them agreed.”
“All of the students agreed.”
With every, use:
“Every one of them agreed.”
“Every one of the students agreed.”
Do not use:
“Every of them.”
Tone, Context, and Formality
Both all and every are neutral, standard English.
Neither is inherently more formal or informal.
Compare:
“All visitors must check in.”
“Every visitor must check in.”
Both are natural in signs, policies, instructions, business writing, and conversation.
Every can sometimes sound more explicitly exhaustive:
“Every applicant must sign.”
This may place slightly more attention on the fact that no applicant is exempt.
All naturally presents the set as a whole:
“All applicants must sign.”
However, this is a matter of perspective and emphasis, not a rigid stylistic rule.
Compare:
“All files were reviewed.”
“Every file was reviewed.”
Both are standard and professional.
Which One Should You Use?
Use all when the following count noun is plural:
“All customers received an email.”
“All students passed.”
Use all with uncountable nouns:
“All equipment was inspected.”
“All advice should be considered carefully.”
Use all before another determiner:
“All the files are ready.”
“All my notes are organized.”
Use all for complete duration:
“We worked all afternoon.”
Use all of with pronouns:
“All of us agreed.”
Use every before a singular count noun:
“Every customer received an email.”
“Every student passed.”
Use every when emphasizing exhaustive member-by-member inclusion:
“Every answer was checked.”
Use every for recurrence:
“We meet every month.”
Use every for intervals:
“Take the medication every four hours.”
Use every one of when needed:
“Every one of the reports was reviewed.”
A practical guide is:
Plural noun? → usually all
Uncountable noun? → usually all
Singular count noun meaning each member? → every
Complete duration? → often all
Repeated time or interval? → often every
When One Choice Sounds Wrong
Some direct substitutions are grammatically incorrect.
Incorrect:
“Every students are ready.”
Correct:
“Every student is ready.”
Also correct:
“All students are ready.”
Incorrect:
“Every information is important.”
Correct:
“All the information is important.”

Compare:
“all my money”
Not:
“every my money”
But:
“every dollar”
Likewise:
“all those people”
or:
“every person there”
The meaning may be similar, but the structure must change.
Common Mistakes

“She studies every day.”
Mistake: Forgetting subject-verb agreement
Correct:
“Every student is ready.”
Correct:
“All students are ready.”
Correct:
“All the information is correct.”
The verb after all depends on the noun or reference.

FAQs
Is it “all students” or “every student”?
Both are correct.
All students uses a plural noun and presents the students as the complete group.
Every student uses a singular noun and includes each student without exception.
Can I use “every” with a plural noun?
Normally not in the standard core construction.
Correct:
“Every student passed.”
Incorrect:
“Every students passed.”
You can also say:
“All students passed.”
Can “every” be used with uncountable nouns?
Not directly in normal quantifier use.
Incorrect:
“Every information was useful.”
Correct:
“All the information was useful.”
Or:
“Every piece of information was useful.”
What is the difference between “all day” and “every day”?
All day means throughout the complete day:
“I worked all day.”
Every day means each day repeatedly:
“I work every day.”
Is it “all of them” or “every of them”?
Use:
“All of them.”
With every, say:
“Every one of them.”
“Every of them” is not standard.
Are “all” and “every” interchangeable?
Not freely.
They may describe the same overall set:
“All employees completed the survey.”
“Every employee completed the survey.”
However, their noun forms, determiner patterns, agreement, and time meanings differ.
Conclusion
Both all and every are correct, but they organize complete coverage differently.
Use all for a complete group, amount, or extent, especially with plural and uncountable nouns:
“all students”
“all information”
“all day”
“all of them”
Use every for each member without exception, normally before a singular count noun:
“every student”
“every piece of information”
“every day”
“every one of them”
Compare:
“All employees completed the survey.”
“Every employee completed the survey.”
A reliable memory rule is: all usually presents the complete total; every normally applies the statement to each individual member without exception.
