Student or Learner
What is the differnce between Present prefect and Past Perfect tense.
Can you please let me know what words fall under them.
Therefore we do not use specific time expression such as yesterday, last week, a few weeks ago etc.
I have given your book to her, The book is with her now. (At the time of speaking)
However you can use the word just to talk about actions that have taken place very recently without mentioning the exact time
You cannot meet her. She has just left.
Past perfect is used to express Completed Action before something in the Past
I had eaten my breakfast, before I went to school,
Please note that the past perfect is the action (had eaten my breakfast) that happened BEFORE the other action in the past (went to school).
