Simple past tense is a tense which adds –ed, -d or ied to regular verbs and changes its form in irregular verbs. For example: “wash washed”, “push pushed”,“play played”, “rain rained” and the irregular forms: “go—went”, “see saw”, “write wrote”, “hide hid”, “take took”, etc.

We use this tense to describe an action that took  place  in  the past and does not have connection with the present situations.

Mostly we use it with the words such as: “yesterday”, “ago”, “last week”, “last month”, “last year”, “last September”, etc.

In addition, we use it in the if clause of conditional type two or improbable conditions.
