The perfect tense is the tense used to indicate a completed
action. Verbs in this tense can be of three types:

  1. #color(blue)"Past"# perfect,
  2. #color(red)"Present"# perfect, and
  3. #color(green)"Future"# perfect.

Here's how you can form them:

  1. #color(blue)"Past"# perfect : Had + past participle
    Eg - The lecture had finished by the time I reached the hall.

  2. #color(red)"Present"# perfect : Have/has + past participle
    Eg - I have seen Harry Potter countless times.

  3. #color(green)"Future"# perfect : Will have + past participle
    Eg - I will have finished writing this summary by 9 pm.

In addition, there is also the perfect continuous tense:

  1. #color(blue)"Past"# perfect continuous : Had + been + present participle
    Eg - I had been waiting for you twenty minutes, when he came over.
  2. #color(red)"Present"# perfect continuous : Have/has + been + present participle
    Eg - I have been reading this book since three days.
  3. #color(green)"Future"# perfect continuous : Will have + been + present continuous
    Eg : When I graduate, I will have been studying for two years.

The highlighted parts indicate the perfect / perfect continuous verbs.
