PAST TENSE

Simple Past tense is used to describe actions that happened at an earlier time and have already completed, for example:

Expressing a sentence in Past Simple means that the action is unrelated to the present, as shown in the following cases:

I lost the keys. He lost the keys.

(Perhaps in this the've found).

She lent me a book. She lent me a book.

(You might already have returned it).

It is also possible to indicate the time when the action is to indicate the time more accurately:

They saw the movie last night. They saw the movie last night.

We went to London yesterday. We went to London yesterday.

In order to form a sentence in past tense we must distinguish two types: regular verbs and irregular verbs.

In the first case are the Simple Past ED adding the ending to the infinitive, while the irregulars are so called not to follow a particular pattern and in this case must be studied individually.
