$\textcolor{w h i t e}{q w e r t y u i o p a s \mathrm{df} g h j k l z x c v b n m}$
The perfect tense is the tense used to indicate a completed
action. Verbs in this tense can be of three types:

1. $\textcolor{b l u e}{\text{Past}}$ perfect,
2. $\textcolor{red}{\text{Present}}$ perfect, and
3. $\textcolor{g r e e n}{\text{Future}}$ perfect.

#### Explanation:

$\textcolor{w h i t e}{q w e r t y u i o p a s \mathrm{df} g h j k l z x c v b n m}$
Here's how you can form them:

1. $\textcolor{b l u e}{\text{Past}}$ perfect : Had + past participle
Eg - The lecture had finished by the time I reached the hall.

2. $\textcolor{red}{\text{Present}}$ perfect : Have/has + past participle
Eg - I have seen Harry Potter countless times.

3. $\textcolor{g r e e n}{\text{Future}}$ 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. $\textcolor{b l u e}{\text{Past}}$ perfect continuous : Had + been + present participle
Eg - I had been waiting for you twenty minutes, when he came over.
2. $\textcolor{red}{\text{Present}}$ perfect continuous : Have/has + been + present participle
Eg - I have been reading this book since three days.
3. $\textcolor{g r e e n}{\text{Future}}$ 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.
