When is the simple past used?
In English, the simple past is most commonly used to talk about actions that were completed in the past.
For example:
How do you form the simple past?
How simple past verbs are formed depends on whether they are regular or irregular.
Past forms of regular verbs
Most commonly, the simple past for regular verbs follows a simple formula:
Most simple past verbs are formed by using the base form of the verb + -ed.
For example:
In a sentence, the simple past form comes after the subject—just like a simple present tense verb would:
- Amy talked to her girlfriend on the phone yesterday.
Amy talked to her girlfriend on the phone yesterday.
- Last month, they watched a lot of scary movies.
Last month, they watched a lot of scary movies.
- I asked two questions.
I asked two questions.
Some regular verbs require a slight spelling change. If the base form of a regular verb already ends in -e, you only need to add a -d for the past:
If the base form of a regular verb ends in a consonant followed by a -y, change the -y to -i and then add -ed:
Finally, if the base form of a regular verb ends with consonant-vowel-consonant, you usually double the last consonant and then add ‑ed:
Memorizing the most important patterns for English past forms of regular verbs can be very helpful:
Past forms of irregular verbs
One of the tricky parts of the simple past is that many verbs are irregular, meaning their past forms don’t follow the regular -ed pattern. Some common irregular verbs and their past tense forms include:
In addition to the irregular verbs above, the verb to be is also irregular. The subjects I and he/she/it take the past form was, while you, we, you (plural), and they all take the past form were:
Negation of the simple past
To form negative sentences in the simple past, add did not (or the contraction didn’t) before the verb. Importantly, you use the base form of the verb rather than the past form in a negative simple past sentence.
Questions in the simple past
You can ask questions using the simple past. Usually, with questions in this tense, you use the word did. However, you don’t add did for questions with was or were. As with negative sentences, you use the base form of the verb that comes after did rather than the past form when forming questions in the simple past.
Yes/no questions
“Wh”questions
Tag questions
Pronunciation of the simple past
The pronunciation of -ed at the end of regular verbs changes depending on the final sound of the base verb.
For any given base verb, it’s important to identify its last sound rather than its last letter, because they aren’t always the same. For example, the verb choose ends in the letter -e, but its final sound is actually a “z” sound.
It’s important to distinguish between voiced and voiceless sounds. Voiced sounds are produced by vibrating your vocal folds, as with the sound “b.” Voiceless sounds, such as “p,” are produced without vibrating your vocal folds.
If the base form of a verb ends in a voiceless sound, the past tense ending -ed is pronounced like the “t” in tea.
If the base form of a verb ends in a voiced sound, the past tense ending -ed is pronounced like the “d” in dog.
Finally, if the base form of a verb ends in the sound “d” or “t,” the past tense ending -ed is its own syllable, pronounced “id”.
Simple past vs. simple present perfect
The simple past isn’t the only way to talk about events in the past in English. There’s also the present perfect, which is formed with the auxiliary verb have (or has for the third person singular) and the past participle.
So how do you know which tense to use?
In general, the simple past is used for events that started in the past and are now finished. Meanwhile, the present perfect is used for events that started in the past but are connected to the present.
For example, you’ll use the present perfect for an action that is continuing into the present, that might happen again, or that affects something in the present.
Compare how the meaning of a sentence changes based on whether you use the simple past or the present perfect:
