1. Simple Explanation
Tenses show when an action happens.
English has three main times (present, past, future) and four aspects (simple, continuous, perfect, perfect‑continuous).
Combining time + aspect gives us 12 basic tenses.
| Time | Simple | Continuous | Perfect | Perfect‑Continuous |
|---|---|---|---|---|
| Present | Present Simple | Present Continuous | Present Perfect | Present Perfect Continuous |
| Past | Past Simple | Past Continuous | Past Perfect | Past Perfect Continuous |
| Future | Future Simple | Future Continuous | Future Perfect | Future Perfect Continuous |

Quick Tips
- S + verb = Subject + verb.
- Singular third‑person adds ‑s / ‑es (e.g., works, prefers).
- Past tense: regular verbs add ‑ed; irregular verbs vary.
- Past participle is the same as the past tense for regular verbs; irregular verbs have unique forms.
- Continuous = action in progress (now, then, etc.).
- Perfect = action finished with relevance to another time.
- Perfect‑continuous = duration of an action that started earlier.
