A verb is a word that shows an action, an occurrence, or a state of being. Every complete sentence needs at least one, which makes verbs the one part of speech you truly can't write around. This guide covers the main types, the rules that trip people up most, and the irregular verbs worth memorizing first.

A verb describes what the subject of a sentence is doing, experiencing, or being. It can show a physical action (run, eat, build), a mental action (think, believe, consider), or a state of being (be, seem, become).
Without a verb, a group of words is just a fragment, not a complete sentence. Even commands, which drop the subject, still need one: "Sit!" or "Listen!"
Verbs fall into several overlapping categories. A single verb can belong to more than one type depending on how it's used.
Describe something physical or mental that happens directly in action.
Describe a state, feeling, or condition rather than an action. Generally not used in continuous tenses.
Work alongside a main verb to build complex tenses, moods, or form questions.
A specialized type of auxiliary verb expressing ability, possibility, permission, or obligation.
Connect the subject to a word that describes or renames it, rather than displaying an action.
Combine a verb with a preposition or adverb to create a brand-new meaning. Only the verb part is conjugated.
This distinction decides whether a verb needs an object to complete its meaning, and it's one of the most common sources of confusion.
| Type | Needs an Object? | Example |
|---|---|---|
| Transitive | Yes, a direct object | She baked a cake. |
| Intransitive | No | The baby slept. |
| Ditransitive | Yes, direct and indirect | She baked him a cake. |
Regular verbs form the simple past and past participle by adding -ed to the root: walk → walked. Irregular verbs don't follow this pattern, and their past forms have to be memorized individually.
| Base Form | Simple Past | Past Participle |
|---|---|---|
| be | was / were | been |
| go | went | gone |
| have | had | had |
| do | did | done |
| see | saw | seen |
| take | took | taken |
| make | made | made |
| get | got | gotten / got |
| know | knew | known |
| think | thought | thought |
| come | came | come |
| give | gave | given |
| find | found | found |
| write | wrote | written |
| speak | spoke | spoken |
Both gerunds and infinitives turn a verb into a noun, but they aren't always interchangeable. A gerund adds -ing to the verb ("Swimming is fun"). An infinitive adds to before the root form ("To swim is fun").
| Use | Form | Example |
|---|---|---|
| Object of a preposition | Gerund only | "I'm interested in learning." |
| After verbs like want, decide, hope | Infinitive only | "I want to leave." |
| After verbs like enjoy, avoid, finish | Gerund only | "I enjoy reading." |
| General or abstract statements | Infinitive | "To exercise is important." |
| Specific or completed actions | Gerund | "I liked exercising this morning." |
English uses 12 main tenses, built from four structures (simple, continuous, perfect, perfect continuous) across three time periods (past, present, future).
| Period | Simple | Continuous | Perfect | Perfect Continuous |
|---|---|---|---|---|
| Present | I walk | I am walking | I have walked | I have been walking |
| Past | I walked | I was walking | I had walked | I had been walking |
| Future | I will walk | I will be walking | I will have walked | I will have been walking |
Each tense has its own rules for when to use it. For a full breakdown of every tense with detailed examples, visit our Verb Tenses guide.
In the active voice, the subject performs the action: "The chef cooked the meal." In the passive voice, the subject receives the action instead, formed with a conjugated form of be plus the past participle: "The meal was cooked by the chef."
Active voice is generally clearer and more direct, which is why most style guides recommend it for everyday writing. Passive voice is useful when the doer of the action is unknown or unimportant: "The window was broken."
A verb has to match its subject in number. Singular subjects take singular verbs; plural subjects take plural verbs.
This gets trickier with collective nouns and compound subjects, where the correct verb form isn't always obvious at first glance.

Some of the most common words in English shift roles depending on the sentence.
| Word | Answer |
|---|---|
| to | Usually a preposition or the marker before an infinitive ("to run"), not a verb on its own. |
| being | Can be a verb form ("She is being kind") or a noun/gerund ("Being on time matters"). |
| have | A main verb showing possession ("I have a car") or an auxiliary verb building tense ("I have finished"). |
| well | Almost never a verb. Usually an adverb ("sings well") or adjective ("feeling well"). |
| like | Can be a verb ("I like coffee"), preposition ("like the wind"), or conjunction ("like I said"). |
Conjugation rules are easy to memorize and hard to apply on the fly, especially with irregular verbs and tricky tenses like the present perfect. Learna AI listens as you speak, corrects verb form mistakes in real time, and explains why the correction fits, rather than just marking it wrong. Learners practicing with Learna report a 94% improvement in tense accuracy after regular conversation practice, since hearing the correct form in context builds the habit faster than memorizing a chart.
Put your grammar knowledge into practice with Learna's learning paths:
A verb is a word that shows an action, an occurrence, or a state of being. Every complete sentence needs at least one.
The main types are action (dynamic), stative, auxiliary, modal, linking, and phrasal verbs.
Transitive verbs need a direct object to complete their meaning, like "read a book." Intransitive verbs are complete without one, like "she laughed."
Irregular verbs don't form their simple past and past participle by adding -ed. Their forms have to be memorized individually, like go, went, gone.
A gerund adds -ing to a verb and always acts as a noun, like swimming. An infinitive adds to before the root form, like to swim. Some verbs only pair with one or the other.
Helping verbs, also called auxiliary verbs, work with a main verb to show tense, form a question, or build a negative statement. The main ones are be, have, and do.
In active voice, the subject performs the action ("She wrote the report"). In passive voice, the subject receives the action ("The report was written by her").
Subject-verb agreement means the verb must match its subject in number: singular subjects take singular verbs, and plural subjects take plural verbs.
Yes, but its role changes. It can be the main verb showing possession, or an auxiliary verb helping form a tense, like the present perfect.
