LoginPast Simple vs. Past Perfect
What is Their Main Difference?
While both tenses tend to talk about past events, there are important differences between them. Past simple tense describes actions that occurred in the past, while past perfect describes events or actions that happened before another past event or action.
Differences
Timeframe
The simple past tense refers to a completed action or event that occurred at a specific time in the past, while the past perfect tense refers to a completed action or event that happened before another action or event in the past. Pay attention to the examples:
She took the train.
Here, the speaker refers to a completed action that happened in the past.
She had packed her stuff before she took the train.
Here, the speaker mentions an action that happened before another action.
Accordingly, past perfect tends to show a stronger connection between the two actions while the simple past tense simply describes the events and actions that took place. Compare the examples:
I ate breakfast this morning. Then I left for work.
I had already eaten breakfast before I left for work.
Past perfect structures clarify the temporal connection between the two events.
Structure
The structure of the past simple and past perfect verbs is different. Let us discuss each.
1. Past Simple
The simple past tense is formed by using the past form of the verb. verbs can be regular or irregular with regard to their past form.
1.1. Regular Verbs
The past forms of regular verbs in English are formed by simply adding '-ed' to the base form of the verb. Have a look:
Walk → Walked
Call → Called
Work → Worked
Love → Loved
1.2. Irregular Verbs
Irregular verbs have their own unique past forms that are not formed by adding '-ed' to the base form. Some irregular verbs don't follow any pattern and must be memorized individually. Take a look at the following table for some examples of irregular verbs:
2. Past Perfect
The past perfect tense is formed by using the auxiliary verb 'had' followed by the past participle form of the main verb. So, the structure is as follows:
Subject + Had + Past participle
Take a look at some example sentences:
I had worked so hard.
I had expected much more.
Signal Words
Past simple tense and past perfect tense can both be used with signal words. Signal words are words that help us establish the order of events in the sentence. Check out the table below to see which signal words are used with each tense:

She finished her homework and then watched a movie.
By the time I arrived, they had already left.

Comments
(25)one thing you need to pay attention to is that while both tenses refer to an action that happened in the past, you should use past perfect when you want to mention that something that occurred before another past event or action.
