When deciding between All Is vs All Are, both forms can be grammatically correct. The right choice depends on what “all” refers to in the sentence. Once you understand this distinction, All Is vs All Are becomes much easier to use correctly in everyday and formal English.
Use is when all refers to an uncountable amount, a whole, or an entire situation. Use are, on the other hand, when all refers to multiple people or plural countable things.
- All the water is gone. → Water is uncountable.
- All the students are ready. → Students is plural.
So the key to All Is vs All Are is to first identify the noun, pronoun, or idea that all represents, and then choose the verb that agrees with it. Don’t assume that all always takes are.
The Core Rule: What Determines “Is” or “Are”?
The basic rule is simple:
- One whole or uncountable amount → is
- Multiple people or things → are
This is an example of subject-verb agreement: the verb must match the grammatical number of the reference represented by all.
“All” Referring to One Whole or Amount
When all refers to an uncountable noun or a whole amount, use is. For example:
- All the water is gone.
- All the information is accurate.
- All the money is safe.
- All the time is valuable.
- All the advice is useful.
Since these nouns are uncountable in these contexts, they take singular verb agreement.
Importantly, quantity doesn’t determine grammatical number. Even a large amount of water is still grammatically uncountable: All the water is gone.
“All” Referring to Multiple People or Things
When all refers to plural countable nouns, use are instead. Consider:
- All the students are ready.
- All the books are on the shelf.
- All the documents carry a signature.
- All the people are waiting outside.
- All the questions are important.
Here, since the nouns are plural, are agrees with them.
When to Use “All Is”
With Uncountable Nouns
Use is when all refers to an uncountable noun.
| Example | Why? |
| All the information is accurate. | Information is uncountable. |
| All the water is cold. | Water is uncountable. |
| Similarly, all the money is mine. | Money is uncountable. |
| And all the advice is helpful. | Advice is uncountable. |
Don’t choose are simply because the sentence describes a large quantity — grammatical number matters more than the size of the amount.
When “All” Refers to an Entire Situation
Sometimes all refers to an entire situation rather than a specific noun. The clearest example is: All is well. Here, all refers to the situation as a whole, meaning that everything is satisfactory or in good order.
Similar expressions include:
- All is lost.
- All is quiet.
- All is not as it seems.
However, this doesn’t mean that all is should replace everything is in every sentence. In everyday American English, everything is often sounds more natural when you mean that everything needed or involved is in a particular state.
With “All of It”
All of it is is correct because it is singular:
- All of it is useful.
- All of it is mine.
- All of it is ready.
- All of it is gone.
Now compare these with:
- All of them are useful.
- All of them are mine.
- All of them are ready.
- All of them are gone.
The pronouns make the distinction clear: it pairs with is, while them pairs with are.
When to Use “All Are”
With Plural Countable Nouns
Use are when all refers to multiple countable people or things. For instance:
- All the students are ready.
- All the books are new.
- Likewise, all the documents are complete.
- All the employees are attending the meeting.
- And all the questions are answered.
You can also use all by itself once the reader already understands the plural reference: “The applicants completed the test. All are eligible for the next stage.” Here, the noun applicants doesn’t need repeating, since the context already makes the reference clear.
Another common example is: All are welcome. Here, all refers to all the relevant people in the context, so are is appropriate.
“All of” + Noun or Pronoun: How Agreement Works
The phrase all of doesn’t automatically determine whether you need is or are — you still need to identify what all of refers to.
“All of It” vs. “All of Them”
With pronouns, the distinction is straightforward:
- All of it is → one thing, amount, or whole
- All of them are → multiple people or things
- All of us are → multiple people
- All of you are → multiple people
For example: All of it is important. All of them are important. Meanwhile, all of us are responsible, and all of you are welcome.
“All of the” + Noun
With all of the, the verb still agrees with the noun it refers to:
- All of the information is accurate.
- All of the water is clean.
- All of the students are ready.
- All of the reports are complete.
Notice that the word of doesn’t change the agreement — what matters is whether the noun is uncountable or plural.
Both all the and all of the can be correct in many contexts:
- All the students are ready. / All of the students are ready.
- All the information is accurate. / All of the information is accurate.
All Is vs. All Are: Side-by-Side Examples
| Reference | Correct form | Example |
| Uncountable amount | is | All the water is gone. |
| Uncountable noun | is | All the information is accurate. |
| Entire situation | is | All is well. |
| Whole represented by it | is | All of it is useful. |
| Plural people | are | All the students are ready. |
| Plural things | are | All the documents are complete. |
| Multiple things represented by them | are | All of them are useful. |
The important point, then, is that “all” doesn’t automatically mean plural — it can refer to a complete amount just as easily as a complete set of separate people or things.
Common Mistakes With “All Is” and “All Are”
Assuming “All” Always Takes “Are”
A common mistake is to see all and immediately choose are.
- Incorrect: All the information are available.
- Correct: All the information is available. Since information is uncountable, is is correct.
Using “Is” With a Plural Countable Noun
Don’t use is with a plural countable noun in a normal construction.
- Incorrect: All the students is ready.
- Correct: All the students are ready. Because students is plural, you need are here.
Using “Are” With an Uncountable Noun
The opposite mistake is possible too.
- Incorrect: All the advice are helpful.
- Correct: All the advice is helpful, since advice is uncountable in standard English.
Ignoring an Implied Reference
Sometimes writers don’t repeat the noun that determines the verb. For example: “The students finished the assignment. All are ready for the next task.” Although the writer doesn’t repeat students after all, the context makes the plural reference clear, so are is correct.
A Simple Test: How to Choose “Is” or “Are”
When you’re unsure, try this three-step method.
Step 1: Find What “All” Refers To
Ask yourself: what does “all” represent here? Look for the noun, pronoun, or idea behind it. For example:
- All the water is cold. → All refers to water.
- All of them are ready. → All refers to them.
Step 2: Identify the Grammatical Number
Next, determine whether the reference is an uncountable amount or whole, or multiple countable people or things. For example: All the water ___ cold (water is uncountable → is), but all the bottles ___ cold (bottles is plural → are).
Step 3: Match the Verb
Finally, use is for an uncountable amount, whole, or entire situation, and are for multiple people or plural things. This approach is more reliable overall than memorizing individual phrases.
Common Expressions: “All Is Well” and Similar Forms
Is It “All Is Well” or “All Are Well”?
“All is well” is the standard expression when all refers to the situation as a whole, as in: “After the inspection, all is well.”
“All are well” is also grammatical, but it carries a different meaning — it normally refers to multiple people or things, as in: “We checked on the children, and all are well.” So the two forms aren’t interchangeable: all is well treats all as a whole situation, while all are well refers to multiple individuals or things.
Is It “All Is Ready” or “All Are Ready”?
Context determines the correct form here too. If all refers to multiple people, use: “All are ready for the meeting.” But if you mean that everything needed is ready, everything is ready often sounds more natural: “Everything is ready for the meeting.” The expression “all is ready” is possible in some contexts, though it’s less common in everyday American English.
Is It “All Is Done” or “All Are Done”?
Again, identify the reference first. “All of the work is done” works because work is uncountable, while “All of the tasks are done” works because tasks is plural. If the reference is already clear, readers can understand all is done — though everything is done often sounds more natural in everyday American English.
All Is vs. All Are in Different Types of Writing
Everyday Conversation
In everyday speech, everything can sometimes make a whole-situation meaning clearer. For example: “Everything is ready.” / “All the students are here.” Both sentences are direct and natural because the reference is clear.
Business and Workplace Writing
The same agreement rules apply in workplace writing. “All of the information in the report is accurate” works because information is uncountable, while “All of the documents on file are complete” works because documents is plural.
Academic and Formal Writing
Academic writing follows the same basic agreement principles: “All the evidence is consistent with the findings” and “All the studies follow the same method.” In each case, the goal is simply to make the reference clear and match the verb correctly.
Special Cases That Need Extra Care
Collective Nouns
Collective nouns such as team, committee, family, and group refer to multiple members but take singular grammatical forms. In American English, writers generally treat collective nouns as singular when the group functions as a single unit: “The committee is meeting today.”
British English, however, more readily allows either singular or plural agreement depending on whether the meaning focuses on the group as a unit or on its individual members: “The committee is meeting today.” / “The committee are disagreeing among themselves.” For a US audience, singular agreement is generally the safest default for a collective noun treated as one unit.
“All the Data Is” vs. “All the Data Are”
Data requires extra care because its agreement varies by context and style. In general writing, writers often treat data as a noncount noun: “The data is clear.” In some technical or scientific contexts, however, data functions as a plural count noun: “The data are clear.” For that reason, follow the convention of your field or publication rather than assuming that data must always take are.
“A Number of” vs. “A Group of”
Expressions containing of don’t all follow the same agreement pattern as all of. For example: “A number of students are absent” — here, a number of carries a plural meaning similar to several. By contrast: “A group of students is waiting outside” — here, group is the grammatical head of the subject and stays singular. These are useful comparisons, but they represent separate agreement patterns, and you shouldn’t treat them as interchangeable with the basic all + is/are rule.

Frequently Asked Questions
Q1. Can “all” refer to only two things?
Yes. All can refer to two or more people or things. For example, “Both reports arrived, and all are complete” can refer to just the two reports if the context makes that clear.
Q2. Is “all of us is” correct?
No. “All of us are” is the standard form because us refers to multiple people: “All of us are responsible for the project.”
Q3. Is “all of you is” correct?
No. In standard English, use “all of you are” because you refers to multiple people in this construction: “All of you are welcome.”
Q4. Can I replace “all” with “everything”?
Sometimes, but not always. Everything usually refers to all things as a whole, while all can also refer to a specific group of people or things: “Everything is ready.” / “All the students are ready.” These sentences don’t carry the same meaning.
Q5. Does “all” always need a noun after it?
No—the noun can be understood from context, as in: “The students finished their work. All are ready.” Here, all clearly refers to the students even though the noun isn’t repeated.
Q6. Is “all is” more formal than “all are”?
Neither form is inherently more formal. The correct choice simply depends on what all refers to: “All is well” is a familiar expression, while “all are welcome” is a common construction referring to multiple people.
Conclusion
The choice between “all is” and “all are” ultimately depends on what all refers to. Use is for an uncountable amount or a whole situation, and are for multiple people or plural things.
So whenever you’re unsure, identify the reference behind all first. If it refers to one whole or an uncountable amount, use is; if it refers to separate people or things, use are.
