Every sentence places an action somewhere in time. Verb tenses are how English marks that: whether something happened, is happening, or will happen, and whether it's a single event, an ongoing process, or something still connected to another moment. Getting tenses right is one of the fastest ways to sound natural in English, and one of the first things that gives away a non-native speaker when it goes wrong.
A verb tense is a change to a verb that shows when an action takes place and how it unfolds over time. English builds its tense system from two ingredients: a time frame (past, present, or future) and an aspect (simple, continuous, perfect, or perfect continuous). Combine the three time frames with the four aspects and you get the 12 core verb tenses in English. Some grammars also mention related forms like going to or used to, but the 12 tenses below are the ones every fluent sentence is built on. Start with the fundamentals on our Learn English page, then use the tenses below to go deeper on any one you want to master.
| Period | Simple | Continuous | Perfect | Perfect Continuous |
|---|---|---|---|---|
| Past | I worked | I was working | I had worked | I had been working |
| Present | I work | I am working | I have worked | I have been working |
| Future | I will work | I will be working | I will have worked | I will have been working |
Present simple describes things that are generally true, or actions that happen regularly, with no emphasis on duration. It's the tense you reach for when talking about routines, facts, and permanent situations.
Present Simple covers formation rules, third-person -s endings, and how it's used for scheduled future events like train timetables.
Explore Present SimplePresent continuous describes an action in progress at the moment of speaking, or a temporary situation happening around now rather than as a permanent habit.
Present Continuous covers formation with be plus -ing, stative verbs that avoid this tense, and its use for near-future plans.
Explore Present ContinuousPresent perfect connects a past action to the present moment, either because it just happened, has happened multiple times, or is still relevant right now.
Present Perfect covers the difference between present perfect and simple past, plus how already, just, and yet change the meaning.
Explore Present PerfectPresent perfect continuous emphasizes the duration of an action that started in the past and is either still happening now or just recently stopped.
Present Perfect Continuous covers when to use it instead of present perfect, and how it pairs with since and for.
Explore Present Perfect ContinuousPast simple describes an action that started and finished in the past, with no direct connection to the present. It's the most common way to talk about finished events.
Past Simple covers regular -ed endings, irregular past forms, and how it contrasts with present perfect.
Explore Past SimplePast continuous describes an action that was ongoing at a specific point in the past, often interrupted by another, shorter action.
Past Continuous covers formation with was/were plus -ing, and its use for setting the scene around another past event.
Explore Past ContinuousPast perfect shows that one action happened before another action in the past, making the sequence of events clear.
Past Perfect covers formation with had plus the past participle, and how it clarifies the order of past events.
Explore Past PerfectPast perfect continuous emphasizes how long an action had been going on before another point in the past.
Past Perfect Continuous covers formation and how it differs from past perfect when duration matters.
Explore Past Perfect ContinuousFuture simple describes actions that haven't happened yet, including predictions, promises, and decisions made in the moment.
Future Simple covers will versus going to, and how each signals a different kind of future.
Explore Future SimpleFuture continuous describes an action that will be ongoing at a specific point in the future.
Future Continuous covers formation with will be plus -ing, and how it's used to make polite, less direct predictions.
Explore Future ContinuousFuture perfect shows that an action will be finished before a specific moment in the future.
Future Perfect covers formation with will have plus the past participle, and how it's used with by and before.
Explore Future PerfectFuture perfect continuous emphasizes the length of an ongoing action that will continue up until a specific future moment.
Future Perfect Continuous covers formation and how it compares to future perfect when duration is the focus.
Explore Future Perfect ContinuousEvery tense above depends on the past tense or past participle of the main verb, and not every verb forms these the regular way. Irregular verbs change form unpredictably instead of just adding -ed, which is why they cause so many mistakes in past and perfect tenses.
| Base Form | Past Simple | Past Participle |
|---|---|---|
| go | went | gone |
| see | saw | seen |
| take | took | taken |
| write | wrote | written |
| begin | began | begun |

When you're not sure which tense a sentence is using, run it through a few quick checks:
Several English tenses can describe the future or the past in more than one way, which is one of the more confusing, and genuinely useful, parts of the tense system.
| Situation | How It's Expressed |
|---|---|
| Talking about the future | "I will call you tomorrow." (Future Simple) · "I am calling him tomorrow." (Present Continuous, for a fixed plan) · "The train leaves at 6." (Present Simple, for a schedule) |
| Talking about past habits | "I played tennis every weekend." (Past Simple) · "I used to play tennis every weekend." (used to, for a habit that stopped) |
| Describing an interrupted past action | "I was cooking when the phone rang." (Past Continuous + Past Simple) |
Knowing the rules for 12 tenses is one thing; choosing the right one instantly in a live conversation is another. Learna AI listens as you speak, flags tense mistakes in real time, and explains why a form doesn't fit rather than just marking it wrong, so the correct pattern becomes automatic through repeated, corrected use rather than memorized rules.

Verb tenses are changes to a verb that show when an action happens (past, present, or future) and how it unfolds (simple, continuous, perfect, or perfect continuous).
English has 12 main verb tenses, formed by combining three time frames with four aspects. Some grammars also count related forms like going to separately.
The 12 tenses are present simple, present continuous, present perfect, present perfect continuous, and their past and future equivalents across the same four aspects.
Tense shows when something happens: past, present, future. Aspect shows how it unfolds: simple, continuous, perfect, perfect continuous. Together they form the 12 verb tenses.
The four aspects are simple, continuous, perfect, and perfect continuous. Each can apply to the past, present, or future, creating 12 total combinations.
Present simple and past simple are the most frequently used tenses in everyday English, since most conversation involves facts, habits, and completed past events.
Present perfect is widely considered the hardest tense, since many languages have no direct equivalent and its use often depends on subtle context rather than a fixed time marker.
Check the auxiliary verb and the main verb's form. Have/has/had plus a past participle signals perfect. Am/is/are/was/were plus -ing signals continuous.
Irregular verbs don't follow the standard -ed pattern in the past tense or past participle. Each one has its own unique form that has to be memorized individually.
Master one time frame at a time, learn the signal words associated with each aspect, and practice with real sentences instead of memorizing rules in isolation.
Learna's AI tutor creates real conversations where you naturally use different tenses, then gives instant feedback so correct usage becomes automatic rather than memorized.
