The 12 Tenses at a Glance
English organises time into three broad zones — present, past, and future — and within each zone it distinguishes four aspects: simple (a basic fact), continuous (an ongoing action), perfect (a completed action with present relevance), and perfect continuous (an action that has been ongoing up to a moment). Three zones × four aspects = 12 tenses.
The table below is your cheat sheet. Keep it bookmarked as you work through the detailed sections below.

Present Tenses
1. Present Simple
When to use it: Facts, habits, routines, and general truths. This is the tense of things that are always — or usually — true.
Structure: base verb (+ -s/-es for he/she/it)
Negative: do not / does not + base verb
Question: Do/Does + subject + base verb?
The sun rises in the east. — permanent fact
I drink coffee every morning. — daily habit
The train leaves at 7:40. — timetable future
Common mistake: Forgetting the -s for third-person singular. Learners often say "She write novels" instead of "She writes novels."
2. Present Continuous
When to use it: Something happening right now at the moment of speaking, a temporary situation, or a planned future arrangement.
Structure: am/is/are + verb-ing
I am working from home this week. — temporary situation
They are meeting the client tomorrow. — planned arrangement
Common mistake: Using stative verbs (think, know, love, want, own) in the continuous. We say "I know the answer" — never "I am knowing the answer."
3. Present Perfect
When to use it: A past action that is relevant now — the time is either unspecified or the result still matters. Key signal words: just, already, yet, ever, never, recently, since, for.
Structure: have/has + past participle
I have just finished the report. — very recent action, result still relevant
She has lived here since 2018. — action that started in the past and continues
Common mistake: Mixing it with specific past-time phrases. Say "I have eaten sushi" (no time given) but "I ate sushi last Tuesday" (specific time → use simple past).
4. Present Perfect Continuous
When to use it: An action that started in the past and has continued up to now, with emphasis on the duration or ongoing nature. It often implies the action is not quite finished.
Structure: have/has been + verb-ing
I have been learning Spanish for three years. — still learning, not finished
You look tired — have you been running? — evidence of recent ongoing activity
Common mistake: Using perfect continuous with stative verbs. Say "I have known him for years" — not "I have been knowing him."
Past Tenses
5. Past Simple
When to use it: A completed action at a specific time in the past. This is the main storytelling tense. Signal words: yesterday, last week, in 2010, ago, when I was young.
Structure: verb + -ed (regular) or irregular past form
She called me this morning. — completed action, specific time
He went to Paris in 2022. — irregular verb (go → went)
Common mistake: Using the past simple for actions still connected to the present. "I have lost my keys" (present perfect, no specific time, still relevant) — not "I lost my keys" when you are still looking for them right now.
6. Past Continuous
When to use it: An ongoing action that was in progress at a specific past time, or a background action interrupted by another event.
Structure: was/were + verb-ing
I was cooking dinner when the doorbell rang. — background action + interruption
At 9 p.m. last night, they were watching TV. — in progress at a specific moment
Common mistake: Using past continuous for quick, completed actions. "She was breaking her leg" implies the breaking was a long process, which makes no sense. Use simple past: "She broke her leg."
7. Past Perfect
When to use it: An action completed before another past action. Think of it as "the past of the past" — it sets the timeline straight in a story.
Structure: had + past participle
When I arrived, the film had already started. — the film started first; my arrival came second
She was nervous because she had never flown before.
Common mistake: Overusing the past perfect. When context makes the order of events clear, simple past works fine. Past perfect is most valuable when the sequence would otherwise be ambiguous.
8. Past Perfect Continuous
When to use it: An action that had been ongoing for a period of time before another past event happened. It emphasises the duration and is often used to explain a state or result.
Structure: had been + verb-ing
He was exhausted because he had been working for 14 hours straight.
They had been waiting for 45 minutes when the bus finally arrived.
Common mistake: Confusing it with the past perfect. Past perfect emphasises completion; past perfect continuous emphasises ongoing duration. Compare: "She had read the chapter" (finished it) vs. "She had been reading for an hour" (the process was ongoing).
Ask yourself: does the number of times or the result matter? Use perfect. Does the duration or ongoing activity matter? Use perfect continuous. "I have written three emails" (count) vs. "I have been writing emails all morning" (duration).
Future Tenses
9. Future Simple
When to use it: A decision made at the moment of speaking, a prediction or belief about the future, a promise, or an offer. Also used for facts about the future.
Structure: will + base verb
I will call you later. — spontaneous decision or promise
It will rain tomorrow. — prediction based on belief
She will be 30 next March. — inevitable future fact
Common mistake: Using will for all future situations. When you have a prior plan or arrangement, use going to or present continuous instead. "I am going to see the doctor this afternoon" (planned) sounds more natural than "I will see the doctor this afternoon" for a pre-arranged appointment.
10. Future Continuous
When to use it: An action that will be in progress at a specific point in the future. It can also make polite enquiries about someone's plans without seeming intrusive.
Structure: will be + verb-ing
At 3 p.m. tomorrow, I will be sitting in my exam.
Will you be using the car this weekend? — polite enquiry
Common mistake: Forgetting that future continuous implies a specific future time reference. Without that time anchor, future simple is usually more natural.
11. Future Perfect
When to use it: An action that will be completed before a specific point in the future. It projects backward from a future moment and says "by then, this will be done."
Structure: will have + past participle
By the time you read this, I will have left the country.
She will have graduated by next summer.
Common mistake: Omitting the "by" phrase. The future perfect almost always needs a deadline reference ("by Friday", "by the time…", "by then") to make sense. Without it, a simple "will finish" usually sounds more natural.
12. Future Perfect Continuous
When to use it: An action that will have been ongoing for a specific duration up to a point in the future. This is the rarest of the 12 tenses in everyday speech, but it is precise and valuable for formal writing and expressing emphasis on duration.
Structure: will have been + verb-ing
By next April, I will have been studying English for ten years.
When she finishes the marathon, she will have been running for over four hours.
Common mistake: Treating this as interchangeable with the future perfect. Use future perfect when the action is completed; use future perfect continuous when the emphasis is on the unbroken duration leading up to that future moment.
These both refer to the future but signal different things. Will = spontaneous decision, promise, or prediction based on opinion. Going to = prior plan or prediction based on present evidence. "Look at those clouds — it is going to rain" (you can see the evidence). "I think it will rain at some point this week" (general opinion).
Quick Tips for Choosing the Right Tense
- Is there a specific time word? "Yesterday", "last year", "in 2019" → use simple past, not present perfect.
- Does the action connect to right now? If the result or relevance to the present is the point → use a present perfect form.
- Are you setting a scene or describing a background? In narratives, continuous forms paint the background; simple forms advance the action.
- Is the verb stative (know, believe, love, own)? Avoid -ing forms with these in almost every tense.
- Is duration the key point? Choose a continuous (or perfect continuous) form over a simple one to highlight how long something has lasted.
- Does one past action predate another? Put the earlier action in the past perfect.
