Choosing between “All is” and “All are” might seem like a small grammar detail, but it can completely change the clarity of your sentence. Many writers get confused because both phrases look correct, yet only one fits depending on the meaning and context. That’s why understanding this rule is essential for clean and professional writing.
The confusion usually comes from the word “all”, because it can refer to a singular idea or a group of multiple things. When “all” represents one complete unit, we use “all is.” But when it refers to several people or items, we use “all are.” This simple shift can make your writing sound natural and grammatically accurate.
In this guide on All Is vs All Are, you’ll learn the exact grammar rules, clear examples, and easy tips to decide which one to use instantly. Whether you’re writing an essay, email, or blog post, this explanation will help you avoid common mistakes and write with confidence.
Why “All Is vs All Are” Confuses So Many People
“All” looks plural. It feels plural. It sounds plural. So people assume the verb should always be are.
That assumption causes mistakes.
Consider these:
- All is well.
- All are welcome.
Both are correct. Different verbs. Same word all.
The confusion happens because “all” does not control the verb. The thing “all” refers to controls it. Once you shift your focus from the word all to the noun behind it, everything clicks.
The Short Answer to All Is vs All Are
If you want the rule in one breath:
Use “all is” for a single whole or uncountable thing.
Use “all are” for multiple countable items.
That’s the core principle. Everything else builds from this.
What “All” Really Is in Grammar
To understand all is vs all are, you need to know what “all” actually does.
“All” can function as:
- A determiner — all people, all water
- A pronoun — all is lost, all are ready
But here’s the key fact:
| Word in Sentence | Looks Like | Actually Controls the Verb |
| All | Plural | The noun it refers to |
So the verb doesn’t agree with all. It agrees with the real subject hiding behind it.
Think of all as a spotlight. It points at something else. That “something else” decides between is and are.
When to Use “All Is” (Singular Verb)
Use “all is” when you’re talking about:
- One complete thing
- A mass or substance
- An abstract idea
- Something you can’t count separately
These nouns are called uncountable nouns.
Common Categories That Use “All Is”
- Time
- Money
- Work
- Information
- Water
- Furniture
- Hope
- Peace
Examples of All Is
- All is calm tonight.
- All the water is gone.
- All the money is missing.
- All hope is lost.
- All the information is correct.
You can’t count water piece by piece in this context. Same with money or information. They act like one lump. So the verb stays singular.
Why It’s Singular
Even if the amount is huge, grammar sees it as one mass.
| Sentence | What “All” Refers To | Countable? | Verb |
| All the sand is wet | Sand | No | is |
| All the work is done | Work | No | is |
| All the equipment is new | Equipment | No | is |
Big quantity does not equal plural grammar.
When to Use “All Are” (Plural Verb)
Switch to “all are” when talking about:
- People
- Objects
- Animals
- Things you can count one by one
These are countable nouns.
Examples of All Are
- All the students are ready.
- All the books are missing.
- All my friends are here.
- All the cookies are gone.
- All the cars are parked.
You can count students. You can count cookies. So the verb becomes plural.
Plural Logic in Action
| Sentence | What “All” Refers To | Countable? | Verb |
| All the players are tired | Players | Yes | are |
| All the houses are old | Houses | Yes | are |
| All the answers are correct | Answers | Yes | are |
If you can say “one, two, three,” you probably need are.
The Fast Test That Never Fails
Here’s a trick teachers love because it works.
Remove the word “all” and look at what’s left.
| Original Sentence | Remove “All” | Singular or Plural? | Correct Verb |
| All the cake ___ gone | The cake ___ gone | Singular | is |
| All the players ___ tired | The players ___ tired | Plural | are |
| All the furniture ___ new | The furniture ___ new | Singular | is |
If the remaining noun takes is, use all is. If it takes are, use all are.
Simple. Reliable. Quick.
When No Noun Appears After “All”
Sometimes the noun is invisible.
- All is lost.
- All are invited.
Now you have to ask: All of what?
Implied Meaning Controls the Verb
| Sentence | Hidden Meaning | Verb |
| All is well | Everything | is |
| All is forgiven | Everything | is |
| All are welcome | All people | are |
| All are required | All participants | are |
If “all” secretly means everything, use is.
If it means all people, use are.

Uncountable vs Countable Nouns Made Simple
This difference drives the entire all is vs all are rule.
| Uncountable Nouns (Use Is) | Countable Nouns (Use Are) |
| Water | Bottles |

| Advice | Suggestions |
Uncountable nouns behave like one unit even if large.
Case Study: Workplace Email Confusion
A manager writes:
“All the staff are required to attend.”
Another writes:
“All the staff is required to attend.”
Which is right?
In US English, staff often acts as a collective singular noun. So “staff is” can be correct when referring to the group as one unit. However, when focusing on individuals, “staff are” appears in British usage.
Better clarity comes from this:
- All staff members are required to attend.
Now there’s no confusion. The noun members makes the verb choice obvious.
All of vs All — Does It Change the Verb?
No. The structure does not change agreement.
| Sentence | Correct? |
| All of the milk is spoiled | ✔ |
| All of the chairs are broken | ✔ |
| All the milk is spoiled | ✔ |
| All the chairs are broken | ✔ |
The noun still decides.
Tricky Sentences That Fool Smart People
These cause hesitation.
- All the team is ready.
- All the team members are ready.
- All the data is accurate.
- All the data sets are accurate.
Why?
Team and data can act as singular masses in modern usage. Add a plural noun like members or sets, and the verb flips to plural.
Common Mistakes with All Is vs All Are
Writers often make these errors:
- ❌ All the information are correct
- ❌ All the furniture are new
- ❌ All the equipment are missing
These nouns never take plural verbs in standard usage.
Correct Versions
| Wrong | Correct |
| All the information are useful | All the information is useful |
| All the furniture are new | All the furniture is new |
| All the equipment are broken | All the equipment is broken |
Collective Nouns and Regional Differences
In US English, collective nouns lean singular.
| Noun | US Usage | Example |
| Team | Singular | The team is winning |
| Government | Singular | The government is debating |
| Family | Singular | The family is traveling |
So:
- All the team is prepared.
But clarity improves with:
- All the team members are prepared.
Memory Trick That Actually Sticks

FAQs
What is the main rule for all is vs all are?
The verb agrees with the noun that “all” refers to. Use is for a single whole or uncountable noun. Use are for plural countable nouns.
Is “all the data is” correct?
Yes in modern standard usage. Data often acts as an uncountable mass noun in everyday English so “all the data is accurate” sounds natural.
Why do we say “all is well” instead of “all are well”?
Because all means everything in this sentence. “Everything” is singular so the verb becomes is.
Can collective nouns change the verb choice?
Yes. Words like team, staff, family often take singular verbs in US English when treated as one unit. Add a plural word like members and the verb becomes are.
Does “all of” change the grammar rule?
No. “All of the water is cold” and “all of the books are missing” follow the same agreement rule. The noun still controls the verb.
Conclusion
This rule feels tricky at first yet it runs on simple logic. Stop looking at the word all. Start looking at the noun behind it. If it behaves like one mass, choose is. If you can count individual items, choose are.
That shift in focus solves almost every sentence. No guesswork. No hesitation. Just clean, confident grammar that sounds natural and professional.
