Recent action
Use just for something a moment ago and already for something completed earlier than expected. Lisa has just called.

Wrong
I lost my keys, so I can't open the door.
Correct
I have lost my keys, so I can't open the door.
The problem is true now, so the earlier action stays connected to the present.
Wrong
She have finished her report.
Correct
She has finished her report.
With he, she, it use has, not have.
Wrong
They have finish dinner.
Correct
They have finished dinner.
After have/has/had use the past participle, not the base verb.
Wrong
You have finished the report?
Correct
Have you finished the report?
Perfect questions start with Have or Has before the subject.
Wrong
She doesn't have finished it yet.
Correct
She hasn't finished it yet.
Perfect negatives use have not / has not, not do / does.
Wrong
When Anna arrived, Tom left already.
Correct
When Anna arrived, Tom had already left.
The leaving happened before Anna arrived, so the earlier past event takes had + past participle.
Common misconceptions
❝ Present perfect is just another way to talk about any past action. ❞
Use it when the past action connects to now. For a finished past time like yesterday or last year, use Past Simple.
❝ Had + past participle is the normal form for every past event. ❞
Use past perfect only when you need to mark an earlier event before another past point.
Skills in this rule (7)
CONNECT_PAST_TO_NOWw5Use a perfect form to link an earlier event to now
Choose a perfect form when an earlier action matters at the present moment. The focus is the result, experience, or unfinished time connection.
CONNECT_EARLIER_TO_LATER_PASTw5Use had + past participle for the earlier of two past points
When two past moments are connected, use had + past participle for the earlier one. The later past event gives the reference point.
HAVE_HAS_HAD_PLUS_PARTICIPLEw5Build perfect forms with have, has, or had plus past participle
Use have with I, you, we, they; has with he, she, it; had for a past reference point. The main verb must be in the past participle form.
USE_ALREADY_YET_JUSTw4Use already, yet, and just with a perfect form
Use already for something earlier than expected, yet in negatives and questions, and just for a very recent action. These markers often appear with present perfect.
ASK_PRESENT_PERFECT_QUESTIONSw4Ask questions with Have/Has + subject + past participle
Start the question with Have or Has, then add the subject and the past participle. Use this to ask about life experience, recent results, or unfinished time up to now.
MAKE_PRESENT_PERFECT_NEGATIVESw4Make negatives with have not or has not plus past participle
Use have not or has not before the past participle. Keep the participle form of the main verb.
PICK_PERFECT_TIME_MARKERSw3Recognize time markers that often go with perfect forms
Words like already, yet, just, ever, never, before, by the time, and up to now often signal a perfect connection to a reference time.
