Have you ever written a sentence like “The accident was happened yesterday” or “We arrived the airport early”? These are two of the most common grammar mistakes English learners make.
The problem usually comes from misunderstanding intransitive verbs. Unlike transitive verbs, they do not take a direct object, so they follow different grammar rules. Once you understand how they work, it becomes much easier to avoid mistakes with passive voice, prepositions, and confusing verb pairs such as rise vs. raise and lie vs. lay.
Intransitive Verbs

An intransitive verb is a verb that does not require a direct object to complete its meaning. The action stays with the subject instead of passing to another person or thing.
For example, each sentence below is complete even though no object follows the verb:
- The bird flew.
- He slept.
- They arrived.
Quick Insight
A quick way to test a verb is to ask “What?” or “Whom?” after it. If no natural answer exists, the verb is probably being used intransitively.
Transitive vs. Intransitive Verbs
Before exploring common mistakes, it’s helpful to compare the two verb types side by side. The biggest difference is whether the verb needs a direct object to complete its meaning.
| Feature | Transitive Verb | Intransitive Verb |
|---|---|---|
| Needs a direct object | Yes | No |
| Question test | Verb + what/whom? → Answer exists | Verb + what/whom? → No answer |
| Example | I bought a car. | I arrived. |
| Passive voice | Usually possible | Normally impossible |
| Main idea | The action affects an object. | The action happens by itself. |
Compare the Difference
Transitive verb:
- She opened the door.
- Opened what? → the door
Intransitive verb:
- The door opened.
- Opened what? → No answer.
Here’s another common comparison:
- He raised his hand. → Raised what? → his hand
- The sun rose slowly. → Rose what? → No answer.
Common ESL Problem
Many learners believe every verb can be used in the passive voice. However, pure intransitive verbs such as arrive, happen, occur, disappear, and vanish normally cannot form passive constructions.
How to Identify an Intransitive Verb
The easiest way to identify an intransitive verb is to check whether the sentence needs a direct object.
Consider these examples:
- The cat sleeps.
- The baby cried.
- We arrived late.
Now ask yourself:
- Sleeps what?
- Cried what?
- Arrived what?
Since none of these questions has a natural answer, the verbs are functioning intransitively.
Remember that adverbs and prepositional phrases do not count as direct objects.
- He ran quickly. → adverb
- She walked to the store. → prepositional phrase
- The sun rose slowly. → adverb
Although extra information follows each verb, none of these words receives the action, so the verbs remain intransitive.
Common Intransitive Verb Traps
Many grammar mistakes happen because learners accidentally treat intransitive verbs like transitive ones. The two most common errors are using them in the passive voice or placing a direct object after verbs that do not allow one.
The verbs below are among the most frequently tested in English exams and also appear regularly in academic writing.
Happen
Happen is a pure intransitive verb. It describes an event that takes place naturally, so nothing receives the action.
Correct examples:
- The accident happened yesterday.
- Something strange happened last night.
Incorrect:
- The accident was happened yesterday.
Grammar Tip
If something happens, it happens by itself. Since there is no direct object, passive forms such as was happened are incorrect.
Occur
Occur has a meaning very close to happen, although it sounds slightly more formal and is common in reports and academic writing.
Correct examples:
- The problem occurred during the meeting.
- The earthquake occurred early in the morning.
Incorrect:
- The problem was occurred during the meeting.
Usage Note
Choose occur when writing formally, but remember that its grammar is exactly the same as happen.
Disappear & Vanish
These two verbs both describe something becoming impossible to see. Since the subject changes state by itself, neither verb normally takes a direct object or forms a passive construction.
| Verb | Correct Example | Incorrect Example |
|---|---|---|
| Disappear | The keys disappeared mysteriously. | The keys were disappeared. |
| Vanish | The magician vanished from the stage. | The magician was vanished. |
Remember
Although vanish and disappear have slightly different shades of meaning, both behave like standard intransitive verbs and normally cannot be used in the passive voice.
Arrive
Arrive causes a different type of mistake. Instead of creating passive forms, learners often place a direct object immediately after the verb.
Correct examples:
- We arrived at the airport early.
- She arrived in London yesterday.
Incorrect:
- We arrived the airport early.
Use arrive at for specific places (the airport, the station, the hotel) and arrive in for cities, countries, and larger areas.
Confusing Pair
Rise vs. Raise
Although these verbs look similar, they follow completely different grammar patterns.
| Verb | Type | Meaning | Example |
|---|---|---|---|
| Rise | Intransitive | Go up naturally | The sun rises every morning. |
| Raise | Transitive | Lift something | Please raise your hand. |
Compare these examples:
- The temperature rose quickly.
- The company raised prices last month.
Easy Rule
If the action happens naturally, use rise. If someone causes the action, use raise.
Lie vs. Lay
Lie and lay create another classic grammar trap because only one of them takes a direct object.
| Verb | Type | Meaning | Example |
|---|---|---|---|
| Lie | Intransitive | Rest in a horizontal position | I need to lie down. |
| Lay | Transitive | Put something down | Please lay the book on the table. |
Compare the difference:
- I’m going to lie on the sofa.
- She laid the blanket on the bed.
The first sentence has no direct object, while the second sentence does because the blanket receives the action.
Linking Verbs and Intransitive Use
Some verbs do not take a direct object because they connect the subject to a description instead. These are commonly called linking verbs.
- She became tired.
- The plan seems reasonable.
- He appeared confident.
Words such as tired, reasonable, and confident are subject complements, not direct objects.
Remember
A subject complement describes or renames the subject. A direct object receives the action of the verb.
Reflexive Structures and Intransitive Verbs
Another common misconception is that adding a reflexive pronoun automatically makes a verb intransitive. In fact, the opposite is often true.
Consider this sentence:
He hurt himself.
Here, himself is the direct object, so hurt is functioning as a transitive verb.
| Sentence | Verb Type |
|---|---|
| She laughed. | Intransitive |
| She hurt herself. | Transitive |
| They arrived. | Intransitive |
| He blamed himself. | Transitive |
Common Mistake
A reflexive pronoun (myself, yourself, himself, etc.) usually functions as the object of the verb. Therefore, the verb often remains transitive, not intransitive.
Quick Guide: Common Intransitive Verbs
Many intransitive verbs describe movement, reactions, changes, or everyday activities. Instead of memorizing them one by one, it is easier to learn them by category and see how they are used naturally in context.
| Category | Common Verbs | Natural Example |
|---|---|---|
| Movement & Travel | arrive, go, come, leave, run, walk, fly | The birds flew south for the winter. |
| Reactions & Communication | laugh, cry, smile, scream, listen, talk | Everyone laughed loudly at the joke. |
| Existence & Change | happen, occur, appear, disappear, vanish, exist | A beautiful rainbow appeared after the storm. |
| Daily Activities | sleep, sit, stand, wake up, work, dance | She works remotely from home. |
Study Tip
Notice that none of the example sentences needs a direct object. The action is complete without answering what? or whom?, which is the clearest sign that these verbs are being used intransitively.
Common Mistakes to Avoid
Most errors with intransitive verbs fall into just a few predictable patterns. If you remember these rules, you’ll avoid many of the mistakes that appear in English exams and everyday writing.
| Common Mistake | Correct Form | Why? |
|---|---|---|
| The accident was happened. | The accident happened. | Happen is intransitive and cannot normally be used in the passive voice. |
| The meeting was occurred. | The meeting occurred. | Occur follows the same rule as happen. |
| We arrived the airport. | We arrived at the airport. | Arrive requires a preposition before a place. |
| I will lay on the sofa. | I will lie on the sofa. | Lie means to rest yourself, while lay needs an object. |
| The sun raised slowly. | The sun rose slowly. | The sun goes up by itself, so use rise, not raise. |
Remember the Pattern
- Pure intransitive verbs normally cannot be made passive.
- Some intransitive verbs require a preposition, such as arrive at or arrive in.
- Verb pairs like rise/raise and lie/lay differ because one is intransitive while the other is transitive.
Practice Quiz: Correct the Grammar Mistakes
Each sentence below contains a common mistake involving an intransitive verb. Rewrite each sentence correctly before checking the answers.
- The terrible car accident was happened yesterday.
- The airplane was vanished from the radar suddenly.
- Don’t worry. We arrived the airport early.
- After a long day, I’m going to lay on the sofa.
- The sun raised slowly behind the mountains this morning.
- An unexpected technical problem was occurred during the meeting.
Answer Key
| No. | Correct Sentence | Why? |
|---|---|---|
| 1 | The terrible car accident happened yesterday. | Happen is a pure intransitive verb, so it cannot normally be used in the passive voice. |
| 2 | The airplane vanished from the radar suddenly. | Vanish describes something disappearing by itself and does not form a passive construction. |
| 3 | Don’t worry. We arrived at the airport early. | Arrive is followed by at for specific places and in for cities or countries. |
| 4 | After a long day, I’m going to lie on the sofa. | Use lie when you rest yourself. Lay requires a direct object. |
| 5 | The sun rose slowly behind the mountains this morning. | The sun goes up naturally, so use rise (past tense: rose), not raise. |
| 6 | An unexpected technical problem occurred during the meeting. | Occur follows the same grammar pattern as happen and is not normally used in the passive voice. |
Quick Check Before You Write
- Can the verb answer what? or whom?? If not, it may be intransitive.
- Avoid passive forms with verbs such as happen, occur, arrive, disappear, and vanish.
- Watch for confusing verb pairs like rise vs. raise and lie vs. lay.
- Remember that arrive is usually followed by at or in, not a direct object.

Thank you
Good list for middle school students who sometimes struggle with this concept. Thank you.
How can tell be intransitive, if we can say “she told me a secret”.
Me is an indirect object, a secret is the direct object.
I don’t think this is correct.
“we danced salsa”
“I escaped prison”
“I jumped the fence”
“I walked the path”
“Lets eat cake”…..
All these verbs can be Intransitive, and often are.
Many of these can be Transitive too
I love English, too, and I love your site! I have a writing game online called Race-2-Write! It’s accessible free (just like your site) at writingames.com. Notice how I used only one “g”? I think the same could be done with your site name: lovenglish. But perhaps you thought of that option before, or that URL name was not available…
If you check out my game, the easiest way to do it is via the PRACTICE mode.
