This article is part of our Complete English Grammar Practice Guide. Also see English Grammar Tenses: The Complete Guide and the English Tense Timeline for deeper explanations.
English has 12 tenses, built from three time frames (present, past, future) combined with four aspects (simple, continuous, perfect, perfect continuous). If that sounds like a lot, the good news is that each tense follows a predictable pattern and serves a clear purpose. This reference chart puts every tense on one page so you can check the form, understand the meaning, and spot the right signal words without searching through an entire textbook.
- All 12 tenses are formed by combining time (present, past, future) with aspect (simple, continuous, perfect, perfect continuous).
- Signal words are powerful clues: "yesterday / ago" points to past simple; "just / already / yet" points to present perfect; "by next week" points to future perfect.
- The five most common tenses in everyday speech are: present simple, past simple, present continuous, present perfect, and future simple (will).
- Stative verbs (know, like, want, need) cannot be used in continuous forms — this is one of the most common ESL errors.
- For exams such as IELTS and Cambridge, mastering the difference between present perfect and past simple is the single highest-value grammar skill.

How English Tenses Work: Time × Aspect
Every English tense is the product of two choices: when the action happens and how the action relates to time within that period. The when gives us three time frames; the how gives us four aspects. Multiply them together and you get the 12 tenses.
Understanding aspect is the key that unlocks the entire tense system. Once you know what each aspect does, you can predict the meaning of any tense combination you encounter. For a deeper look at aspect, visit our Grammar Practice Centre.

All Four Present Tenses
Present tenses cover actions connected to now — from permanent truths to activities happening at this exact second, to experiences stretching across a person's life. Choosing the right present tense is often more about aspect (completed vs ongoing, result vs duration) than about timing.
Present Simple
When to use: permanent facts, daily habits, routines, timetables, instructions, general truths, and commentary (sports broadcasts, recipes).
Water boils at 100°C. (fact)
He reads for 30 minutes every morning. (habit)
The bus leaves at 7:45. (timetable)
Present Continuous
When to use: actions happening right now, temporary situations, fixed future arrangements, and changing or developing trends. Important: stative verbs (know, want, love, own) cannot be used in this form.
She is writing an email right now. (in progress)
We are staying at the Grand Hotel this week. (temporary)
I am meeting the director on Monday. (arrangement)
Present Perfect
When to use: past actions with a clear present result, life experiences (without a specific time), actions that started in the past and continue now (with for/since), and recent events whose exact time is not stated.
I have lost my passport. (result: I don't have it now)
She has visited Japan three times. (life experience)
They have lived here since 2015. (ongoing to now)
Present Perfect Continuous
When to use: activities that started in the past and are still going on — especially when you want to emphasise how long the activity has been happening, or when the activity has visible present results.
He has been studying for this exam for three weeks.
You look tired — have you been running?
To choose between present perfect and present perfect continuous, ask yourself: How many/How much? (result) → present perfect. How long? (duration) → present perfect continuous.
All Four Past Tenses
Past tenses describe actions, states, and processes anchored in a time before now. They range from specific completed events (past simple) to ongoing background situations (past continuous) to sequences and reported speech (past perfect). See also our full grammar tenses guide for more examples.
Past Simple
When to use: completed actions at a specified or implied past time, a sequence of past events, past habits, and states that no longer exist.
She graduated in 2021.
He woke up, got dressed, and left. (sequence)
We used to play chess every Sunday. (past habit)
Past Continuous
When to use: actions in progress at a specific past moment, a background action that was interrupted by a shorter past simple event, and two simultaneous past activities.
I was reading when the phone rang. (interrupted)
While she was cooking, he set the table. (simultaneous)
At 8 pm last night, they were watching a film. (specific moment)
Past Perfect
When to use: an action that happened before another past event or before a specific past time — the "past of the past." Also used in reported speech (backshift) and third conditional.
When I arrived, she had already left.
He told me he had seen the film before. (reported speech)
If they had studied, they would have passed. (3rd conditional)
Past Perfect Continuous
When to use: an activity that was in progress for a period of time up to a past moment. Often explains the cause of a past state: the visible evidence of an earlier ongoing action.
She was exhausted because she had been running for two hours.
They had been waiting for over an hour when the bus finally came.
All Four Future Tenses
English expresses the future in several ways. The most important distinction is between will (spontaneous decisions, predictions based on belief) and be going to (pre-planned intentions, evidence-based predictions). The continuous and perfect future forms follow the same aspect logic you already know from present and past.
Future Simple (will)
When to use: predictions, promises, offers, spontaneous decisions made at the moment of speaking. Use be going to for plans decided in advance and for predictions backed by visible evidence.
I will call you later. Promise.
Look at that child — she is going to fall! (evidence)
I think prices will rise next year. (prediction/belief)
Future Continuous
When to use: an action that will be in progress at a specific future moment, and for polite enquiries about future plans (it sounds less direct than a simple question).
At 10 pm tonight I will be flying to New York.
Will you be joining us for lunch? (polite enquiry)
Future Perfect
When to use: an action that will be completed before a specific future point. Typical contexts: project deadlines, milestones, future reporting.
By Friday, I will have submitted the report.
By the time you read this, they will have landed.
Future Perfect Continuous
When to use: emphasising the duration of an activity up to a specific point in the future. This is the rarest of the 12 tenses and is mainly used in formal writing, planning contexts, and advanced exam responses.
By December, she will have been teaching English for 20 years.
When we reach the summit, we will have been climbing for six hours.
Signal Words Quick-Reference
Signal words are time expressions that appear alongside specific tenses. They are not absolute rules — context always matters — but they are highly reliable guides in grammar exercises and exams such as IELTS and Cambridge.
| Signal Word / Phrase | Most Likely Tense(s) |
|---|---|
| yesterday, last week, in 2021, ago | Past Simple |
| while, when (+ background), at that moment | Past Continuous |
| by the time, before/after, already (past), never…before | Past Perfect |
| just, already, yet, ever, never, recently, so far, for/since (to now) | Present Perfect |
| for, since, all morning, how long (ongoing) | Present Perfect Continuous |
| always, every day, usually, never (general) | Present Simple |
| now, at the moment, currently, today, look! | Present Continuous |
| tomorrow, next week, soon, probably, I think | Future Simple |
| at this time tomorrow, all day next week, still (future) | Future Continuous |
| by next Monday, by the time (future), before (deadline) | Future Perfect |
Most Common Tense Mistakes
Even advanced learners make predictable tense errors. Knowing the most common mistakes helps you proofread your own writing and speech more effectively.
- Present perfect with a specific past time: ✗ "I have arrived yesterday." → ✓ "I arrived yesterday." Use past simple when a specific time is stated.
- Stative verb in continuous form: ✗ "She is knowing the answer." → ✓ "She knows the answer." Verbs like know, want, like, believe, own describe states, not activities.
- Will vs going to confusion: ✗ "I will study medicine" (after years of planning). → ✓ "I am going to study medicine." Planned intentions use be going to.
- Missing the past perfect in sequences: ✗ "When I arrived, she left already." → ✓ "When I arrived, she had already left." Use past perfect to clarify which action came first.
- Overusing present continuous for habits: ✗ "I am walking to work every day." → ✓ "I walk to work every day." Habits and routines use present simple, not continuous.

How to Choose the Right Tense: A Decision Guide
When you are not sure which tense to use, work through these questions in order:
- When does the action happen? Before now (past) / at or near now (present) / after now (future)?
- Is the action complete or in progress? Complete → lean towards simple or perfect. In progress → lean towards continuous.
- Does it connect two time frames? (e.g., a past action with present relevance, or a future action completed before another future event) → perfect aspect.
- Do you want to emphasise duration? Yes → perfect continuous.
- Are there any signal words in the sentence? Match them to the signal word table above.
This five-step process eliminates most of the 12 tenses quickly, leaving you with one or two candidates. Practise applying it in our Grammar Quiz until it becomes automatic.
