A student looks at the board and asks, “Why is it I am but they are? And why is it has been but not has being?” If you teach ESL, you've heard some version of that question many times.
Most learners don't need only a be verb list. They need a way to diagnose what went wrong, fix it quickly, and decide when a be verb is correct, awkward, or unnecessary. That's especially true for intermediate students, who may know the forms by memory but still write sentences like The report is been finished or overuse is and are in every paragraph.
This guide treats the verb be as both a grammar topic and a problem-solving topic. You'll get the full list, but you'll also get explanations, error patterns, classroom language, and revision strategies that make the forms usable in real speech and writing.
Why Is the Verb Be So Important and Confusing
The verb be sits everywhere in English. Students use it to talk about identity, age, feelings, location, time, description, and grammar patterns like the passive voice. It also appears inside many tenses, so learners meet it early and keep meeting it forever.
That constant exposure is exactly why mistakes with be feel so frustrating. A student can build a strong vocabulary and still produce sentences like She are happy or They was late. These aren't random slips. They usually show that the learner hasn't fully connected the verb form to the subject.
Why the forms don't look consistent
English doesn't give learners one neat present-tense pattern for this verb. Instead, it gives them am, is, are, was, were, been, being. Standard grammar references explain that this irregular pattern comes from a historical merger of multiple Old English verbs from different Indo-European roots, which is why modern English has different forms for first-person singular, third-person singular, and plurals, a pattern later codified in prescriptive grammar in the 18th and 19th centuries (historical explanation of is/are agreement).
That history matters in the classroom because it helps you say something honest to students: “Yes, this verb is strange. No, you're not imagining it.”
Practical rule: Treat be as a form-matching system. First choose the subject. Then choose the correct form.
Why students keep mixing it up
Three things usually cause trouble:
- Subject mismatch: Students know the sentence meaning, but they don't match the verb to the grammatical subject.
- Participle confusion: They mix being and been because both look like non-basic forms.
- Writing habits: They use is and are too often because those forms feel safe.
A good be verb list helps with memory. A good teacher goes one step further and shows how each form behaves in a sentence.
Quick Reference Chart All Be Verb Forms
If a student wants the answer fast, this is the part to save. The core be verb list has eight forms: am, is, are, was, were, be, being, been. A practical teaching reference should also show tense function and subject agreement, because forms like I is are not small mistakes. They are category errors in subject-verb agreement (complete eight-form reference with agreement patterns).

The core chart
| Form | Main use | Typical subject pairing | Example |
|---|---|---|---|
| am | present | I | I am ready. |
| is | present | he / she / it | She is tired. |
| are | present | you / we / they | They are here. |
| was | past | usually singular subjects | He was late. |
| were | past | usually plural subjects | We were early. |
| be | base form | after modals, infinitives, commands | You must be careful. |
| being | present participle | progressive and some passive structures | The room is being cleaned. |
| been | past participle | perfect structures | They have been busy. |
One quick warning about future forms
Many student charts include will be, and that's useful in teaching. But will be is not a separate ninth form. It is the modal will plus the base form be.
That distinction helps when students ask why all subjects use the same future pattern:
- I will be
- she will be
- they will be
The chart is easier to remember if students separate forms from combinations. The form is be. The combination is will be.
The shortest classroom summary
If you need a fast board note, write this:
- Present: I am, he/she/it is, you/we/they are
- Past: singular usually was, plural usually were
- Base: be
- -ing form: being
- Past participle: been
That short version handles most beginner and intermediate questions before you move into deeper usage.
The 8 Forms of Be Explained With Examples
Memorizing the be verb list is helpful, but students improve faster when each form has a job. I teach each one with three patterns: statement, negative, and question. That keeps the form attached to real sentence use.
Am
Use am only with I in the present.
- Positive: I am tired.
- Negative: I am not ready.
- Question: Am I in the right room?
Classroom note: if a learner says I is or I are, stop and reconnect the subject first. The problem is pairing, not spelling.
Is
Use is with he, she, it, and singular nouns in the present.
- Positive: She is my teacher.
- Negative: He isn't at home.
- Question: Is the lesson difficult?
This is one of the most frequent forms in student writing because it appears in descriptions, definitions, and location statements.
Are
Use are with you, we, they, and plural nouns in the present.
- Positive: They are hungry.
- Negative: We aren't late.
- Question: Are you okay?
Students often overgeneralize is and produce My parents is. I usually circle the subject and ask, “One or more than one?” That often fixes the problem immediately.
Was
Use was for many singular subjects in the simple past.
- Positive: The class was noisy.
- Negative: I wasn't sick.
- Question: Was the film interesting?
Was also appears in passive structures and past descriptions, which is why learners meet it in many contexts.
Were
Use were for plural subjects in the simple past, and also in some hypothetical patterns discussed later.
- Positive: They were excited.
- Negative: We weren't ready.
- Question: Were the answers correct?
For beginners, start with the everyday pairing. Save hypothetical were for a later lesson if needed.
Be
Use be as the base form. Students usually see it after modals, after to, or in commands.
- Positive: You should be polite.
- Negative: Don't be rude.
- Question: Could this be true?
This form often confuses learners because it doesn't show person agreement by itself. The modal or surrounding structure controls it.
Being
Use being as the present participle. It often appears in progressive or passive-related structures.
- Positive: The road is being repaired.
- Negative: He isn't being honest.
- Question: Why is she being so quiet?
A practical explanation helps here. Being often suggests an ongoing state or process, not a finished one.
Been
Use been as the past participle. It commonly appears with have, has, had.
- Positive: I have been busy.
- Negative: She hasn't been there.
- Question: Have they been helpful?
Students often swap been and being because both are non-finite forms. The fastest fix is this question: “Do you already have have/has/had?” If yes, been is often the better candidate.
A compact teaching table
| Form | Main clue | Common classroom prompt |
|---|---|---|
| am | present with I | “What goes with I?” |
| is | present singular | “One person or thing?” |
| are | present plural / you | “Plural or you?” |
| was | past singular | “Past time and one?” |
| were | past plural | “Past time and more than one?” |
| be | base form | “After a modal or to?” |
| being | ongoing process/state | “Happening now or in progress?” |
| been | perfect form | “Do you have have/has/had?” |
Many errors disappear when students stop asking “Which be verb sounds right?” and start asking “What structure am I building?”
One pattern teachers should keep repeating
Keep grammar recognition and sentence production together. Don't just ask students to underline is or were. Ask them to change:
- positive to negative
- statement to question
- present to past
That simple transformation work reveals whether they control the form.
Understanding Be as a Linking Verb vs Auxiliary Verb
One reason be causes confusion is that it doesn't always do the same job. Sometimes it links the subject to information about the subject. Sometimes it helps another verb build a tense or voice. Style guides often classify be as a linking or stative verb, but the same family of forms also works as an auxiliary in compound structures such as those using being and been (Grammarly explanation of to be as stative and auxiliary).

Be as a linking verb
A linking verb connects the subject to a noun, pronoun, or adjective that describes or identifies it.
Examples:
- She is a doctor.
- The soup is cold.
- They were tired.
In these sentences, be doesn't show an action. It connects the subject to information.
Be as an auxiliary verb
An auxiliary verb helps form another grammatical structure. It supports the main verb.
Examples:
- She is working.
- They were playing.
- The door was closed by the guard.
In those examples, working, playing, and closed carry the main lexical meaning. Be helps build the tense or the passive voice.
Side-by-side comparison
| Sentence | Role of be | What follows |
|---|---|---|
| She is a doctor. | linking | noun |
| She is happy. | linking | adjective |
| She is working. | auxiliary | present participle |
| The car was repaired. | auxiliary | past participle |
This comparison matters because students often see the same word and assume the same grammar. But is in She is friendly and is in She is studying are not doing the same job.
A classroom shortcut
I give students two questions:
- Does the sentence describe the subject?
- Or does be help another verb?
If the answer to the first question is yes, it's probably linking. If the answer to the second is yes, it's auxiliary.
A useful test is to look at the word after be. If it's an adjective or noun, linking is likely. If it's part of a verb phrase, auxiliary is likely.
Why this distinction improves writing
This isn't only grammar terminology. It affects editing too. A sentence with a linking be may be perfectly natural: The answer is correct. But a sentence with an auxiliary in passive voice may invite revision if the writer wants a more direct style: The manager approved the plan instead of The plan was approved.
That's why a be verb list alone isn't enough. Students also need to recognize function.
Mastering Continuous and Perfect Tenses With Being and Been
For many learners, being and been are the hardest pair in the whole be verb list. They look similar, they're both non-basic forms, and they often appear in longer verb chains. But their jobs are different.
How to think about being
Being is the present participle form. It usually signals an ongoing process or a temporary behavior.
Examples:
- The room is being cleaned.
- He is being careful today.
- The problem was being discussed.
In passive structures, being often appears between a form of be and a past participle: is being repaired, was being watched.
How to think about been
Been is the past participle form. It typically appears after have, has, had.
Examples:
- I have been busy.
- She has been a teacher for years.
- They had been waiting before lunch.
If your student already has have, has, or had, they should immediately check whether been is needed. For extra practice with these larger tense patterns, a good follow-up is targeted ESL verb tenses exercises.
The contrast students need most
Here's the cleanest contrast:
| Pattern | Example | Meaning focus |
|---|---|---|
| is being + past participle | The bridge is being repaired. | process happening now |
| has been + adjective/noun | The bridge has been unsafe. | state up to now |
| has been + -ing verb | She has been studying. | activity over a period |
Notice that has being is not the normal perfect pattern. That's why sentences like He has being a developer sound wrong.
Fast correction drills
Ask learners to fix these:
- The code is been reviewed. → The code is being reviewed. / The code has been reviewed.
- She has being nice today. → She has been nice today.
- The walls have being painted. → The walls have been painted.
The key is to identify what the sentence means first. Is it a current process, or a completed or continuing result? Then choose being or been.
Don't teach being and been as twins. Teach them as signals for different structures.
Advanced Usage Was Were Subjunctive and Passive Voice
Intermediate students often feel comfortable with I was and they were, then suddenly run into If I were you or The building is being renovated. These are the places where memorized rules stop being enough.
A common weakness in many online explanations is that they mention edge cases without connecting them to real learner mistakes, especially the subjunctive were and passive constructions involving being and been (discussion of tricky edge cases and errors like “The code is been reviewed”).
When were does not mean plural past
In normal past-tense use, students learn:
- I/he/she/it was
- you/we/they were
That works for everyday statements. But in unreal or hypothetical situations, English often uses were:
- If I were you, I'd apologize.
- She acts as if she were the manager.
- I wish it were easier.
This is often called the subjunctive or an irrealis pattern. Students don't need heavy terminology first. They need the idea: the sentence is not describing reality. It is imagining it.
Building the passive voice
The passive voice uses a form of be plus a past participle:
- The email was sent.
- The homework is checked every Friday.
- The road is being repaired.
- The final decision has been made.
The challenge is not the formula alone. It's choosing the right form of be inside the tense.
A practical passive table
| Tense idea | Passive form | Example |
|---|---|---|
| present simple | is / are + past participle | The doors are locked. |
| past simple | was / were + past participle | The file was deleted. |
| present continuous | is / are being + past participle | The plan is being revised. |
| present perfect | has / have been + past participle | The issue has been resolved. |
Here, being and been become easier. They are not random. They are signals inside passive patterns.
The most useful correction question
When a learner writes The code is been reviewed, ask:
- Do you mean it is happening now?
Then use is being reviewed. - Do you mean it happened already?
Then use has been reviewed or was reviewed, depending on the meaning.
That one contrast solves many intermediate-level mistakes.
Common Learner Errors and How to Fix Them
A lot of students searching for a be verb list are not really trying to memorize forms. They're trying to fix sentences that keep going wrong. Teaching sources on revision make the same point: learners often need a framework for when to keep be, when to replace it, and when to rewrite the whole sentence (writing-focused guidance on replacing or revising be verbs).

High-frequency grammar mistakes
Here are errors teachers see constantly.
Wrong subject pairing: They was happy.
Correct: They were happy.
Why: The subject is plural, so the past form should match it.Incorrect negative form: He no is a doctor.
Correct: He is not a doctor.
Why: English negatives with be use not after the verb.Question word order problem: She is from Spain?
Correct: Is she from Spain?
Why: Questions with be usually invert the subject and the verb.Participle confusion: The report is been finished.
Correct: The report is being finished or The report has been finished.
Why: Choose the form that matches the meaning.Missing be verb: My brother happy.
Correct: My brother is happy.
Why: English usually needs a linking verb before an adjective predicate.
A correction routine that works
I like a simple three-step routine:
- Find the subject
- Choose the time
- Check the structure around be
If the sentence contains have/has/had, check for been. If it contains a progressive or passive process, check for being. If it's just description, identity, or location, check ordinary agreement.
Students can build that habit with short, focused online ESL grammar practice between lessons.
When be verbs make writing weak
Not every is or are is bad. Many are necessary. But some sentences become flat because the writer hides the actual action.
Compare these:
The dog is in possession of the ball.
Better: The dog has the ball.The committee is in discussion about the plan.
Better: The committee is discussing the plan.There are many students who are interested in robotics.
Better: Many students are interested in robotics.
Better still, if context allows: Many students study robotics enthusiastically.
A useful principle is this: keep be when you need identity, description, state, or a specific grammar structure. Replace it when a stronger verb expresses the idea more directly.
A quick video explanation can help students hear these patterns in action:
Editing lens: Ask, “Is this sentence describing a state, or is it hiding an action?”
Classroom Activities and Online Practice Exercises
Students won't master the be verb list by reading it once. They need repeated use across speaking, writing, correction, and quick recall. That matters because corpus research in academic English, including work analyzing 554 verbs across disciplines, shows that verb choice is systematic and that be remains one of the most important verbs for learners to control as both a linking and auxiliary verb (academic-English verb research on ScienceDirect).
Low-prep classroom activities
- Find someone who: Give prompts like “Find someone who is tired,” “Find two classmates who were at the library yesterday,” or “Find someone who has been to another city.”
- Error auction: Put incorrect be-verb sentences on the board. Teams bid on the ones they think they can correct.
- Transformation races: Students change one sentence through four versions, such as statement, negative, question, and past.
- Passive or active sorting: Mix examples such as The door is closed and The staff are closing the door. Students decide which ones describe a state and which ones describe an action.
Online reinforcement
Online practice works best when it targets one form or one contrast at a time. Teachers often want assignable tasks, progress tracking, and enough variety to recycle old errors without boring the class. One option is The Kingdom of English, a gamified ESL practice platform with 60 grammar topics, along with listening and reading tasks, designed for assignable classroom and homework use. For lesson ideas that pair well with grammar review, see these ESL games for the classroom.

What to practice first
Don't assign everything at once. Start with this order:
- am / is / are
- was / were
- be after modals
- being vs been
- passive forms
- editing overused be verbs
That sequence keeps recognition, production, and revision connected.
If you want students to move beyond memorizing forms and start using them accurately in speech and writing, The Kingdom of English offers structured ESL practice in grammar, reading, listening, and writing, with assignable activities and progress tracking that fit classroom teaching, tutoring, or homework.
