- 3 Basic Time Frames
- Past: Describes events that occurred before the present.
- Present: Refers to actions happening now or facts that are always true.
- Future: Points to events that will occur after the present.
- 4 Main Types (Aspects)
- Each time frame (Past, Present, Future) includes 4 different types. Here are the basic rules for their usage.
A. Simple Tenses (For facts, habits, or completed single actions)
- Present Simple
- Rule: Use the base verb and add -s or -es for he/she/it.
- When to use: For daily routines, habits, and general truths.
- Example: I eat lunch every day. She works hard.
- Past Simple
- Rule: Use the base verb + -ed for regular verbs or the second form of irregular verbs like went, ate, saw.
- When to use: For actions completed in the past at a specific time.
- Example: I ate lunch an hour ago. We watched a movie yesterday.
- Future Simple
- Rule: 'will' followed by the base verb.
- When to use: For predictions, quick decisions, or future promises.
- Example: I will eat lunch later.
I will call you tonight.
B. Continuous (Progressive) Tenses (For ongoing or in-progress actions)
- Present Continuous
- Rule: am/is/are + Verb-ing.
- When to use: Things happening right now at the moment of speaking.
- Example: I am eating lunch right now.
They are playing football.
- Past Continuous
- Rule: was/were + Verb-ing.
- When to use: An action that was in progress at a specific moment in the past (often interrupted by another event).

- Future Continuous
- Rule: will be + Verb-ing.
- When to use: An action that will be happening at a specific time in the future.
- Example: At 1:00 PM tomorrow, I will be eating lunch.
C. Perfect Tenses (Connecting two time frames or showing completion)
- Present Perfect
- Rule: have/has + Past Participle (3rd form, e.g., eaten, done, seen).
- When to use: An action that happened in the past, but the time is not stated, or it connects to/affects the present.
- Example: I have eaten lunch already (so I am not hungry now).
- Past Perfect
- Rule: had + Past Participle.
- When to use: An action that happened before another action in the past.
- Example: I had eaten lunch before the meeting started.
- Future Perfect
- Rule: will have + Past Participle.
- When to use: An action that will be completed before a specific time in the future.
- Example: By 2:00 PM tomorrow, I will have eaten lunch.
D. Perfect Continuous Tenses (Duration up to a point)
- Present Perfect Continuous
- Rule: have/has been + Verb-ing.
- When to use: An action that started in the past and is still continuing right now.
- Example: I have been studying for two hours.
- Past Perfect Continuous
- Rule: had been + Verb-ing.
- When to use: An ongoing action in the past that continued up until another past moment.
- Example: I had been studying for two hours before my friend arrived.
- Future Perfect Continuous
- Rule: will have been + Verb-ing.
