The Foundation
Think of a tense as a railway timetable for an action. A verb is a train; the tense tells you when the train runs and whether it's still moving. “The train leaves at 6” (a fixed routine), “the train is leaving now” (moving as we speak), “the train has left” (gone — and that affects you right now, you've missed it). Same train, three timetables. Master the timetable and you always know which form to use.
Every English tense answers just two questions at once:
The four “shapes” in one line each, using the everyday verb eat:
The fourth shape, Perfect Continuous (I have been eating), simply says an action ran for a while and still matters — it's the “duration” shape. Get these four, cross them with three times, and you own the grid.
Visual Architecture
Two pictures do the heavy lifting. First, the family tree — every tense hangs off one of three times. Second, a decision flowchart — the exact questions to ask yourself to pick the right tense in a real sentence.

Here is the complete grid. V1 = base verb (eat), V2 = past (ate), V3 = past participle (eaten), V-ing = the “-ing” form. Learn the formula column and the rest follows.
| Tense | Formula | Use it for | Example (British) |
|---|---|---|---|
| Present Simple | V1 / V1-s | Habits, facts, timetables | She catches the 8:10 local. |
| Present Continuous | am/is/are + V-ing | Happening now; fixed near-future plans | They are playing cricket. |
| Present Perfect | have/has + V3 | Past action, result matters now; experience | I have just eaten. |
| Present Perfect Cont. | have/has been + V-ing | Duration up to now | She has been studying for hours. |
| Past Simple | V2 | Finished action at a finished time | We visited Jaipur last year. |
| Past Continuous | was/were + V-ing | A scene in progress in the past | It was raining at midnight. |
| Past Perfect | had + V3 | The earlier of two past events | The train had left before we came. |
| Past Perfect Cont. | had been + V-ing | Duration before a past moment | He had been waiting an hour. |
| Future Simple | will + V1 | Instant decisions, predictions, promises | I will call you. |
| Future Continuous | will be + V-ing | In progress at a future time | This time tomorrow I will be flying. |
| Future Perfect | will have + V3 | Completed by a future point | By June we will have finished. |
| Future Perfect Cont. | will have been + V-ing | Duration by a future point | By May she will have been teaching 30 years. |
The signal-word shortcut. In an exam you rarely have time to reason it out — you spot a signal word and the tense falls out automatically.
| Signal words | They point to |
|---|---|
| always, usually, every day, on Sundays | Present Simple |
| now, right now, at the moment, look!, listen! | Present Continuous |
| just, already, yet, ever, never, so far, recently | Present Perfect (British) |
| for + a length, since + a start point | Perfect / Perfect Continuous |
| yesterday, last week, in 2019, ago, then | Past Simple |
| while, as, when (background) | Past Continuous |
| before, after, by the time, already (in the past) | Past Perfect |
| tomorrow, next week, soon, by + future time | Future forms |
Level 3 · the expert edge. A few professional-grade refinements the textbooks rush past:
- Timetable future: a fixed schedule takes the present simple, not a future form — The train leaves at 08:15 tomorrow.
- Diary future: a personal arrangement takes the present continuous — I'm seeing the dentist at 3.
- State verbs (know, believe, own, love, need) resist the continuous — I am knowing → I know.
- been vs gone: She's been to Wales (visited, back now) ≠ She's gone to Wales (still there).
- The British "have got": possession in the present — I've got two tickets — looks perfect in form but means simple present, and never goes continuous.
