To express ourselves clearly, we need to be able to differentiate between present, past and future actions. For now, we will focus on the eight past and present tenses.
In English, we generally distinguish between the simple form (habitual and non-continuous actions) and the progressive form (continuous actions). Additionally, you'll come across the word "perfect" (lat. perfectum = complete), which focuses on how a past action effects the present.
Obviously, all past tenses can be used to express everything the respective present tense does, but as past action.
For the tenses we will need to revise the four main forms of a verb, which thankfully aren't that complicated.
To form the second or third form of a regular verb, simply add -ed to the infinitive.
The Present Participle is the ing-form.
But there are quite a few verbs that are irregular, including some of the most important verbs like to be, to go and to see. You can find a full list of irregular verbs here.
Infinitive | Simple Past | Past Participle | Present Participle |
walk | walked | walked | walking |
look | looked | looked | looking |
come | came | come | coming |
go | went | gone | going |
Simple Present | Present Progressive | Present Perfect Simple | Present Perfect Progressive |
I walk to school every day. | I am walking to school now. | I have walked to school three times this week. | I have been walking to school for 20 Minutes. |
Infinitive (he/she/it: + s) | am/are/is + present participle | have/has + past participle | have/has + been + present participle |
Simple Past | Past Progressive | Past Perfect Simple | Past Perfect Progressive |
I walked to school this morning. | I was walking to school at 8am. | I had walked to school before I sat down to eat breakfast. | I had been walking to school when my phone rang. |
past participle | was/were + present participle | had + past participle | had + been + present participle |
Simple Present is used when an action is habitual or happens repeatedly. It's also used with certain words like to love, to like, to have since they describe a general state (we'll talk about this later). This includes characteristics as well.
Signal words
Examples
Present Progressive is used when an action is happening at the very moment. It also includes temporary actions and trends.
Signal words
Examples
Present Perfect Simple is used when something has happened in the past but has a connection to the present or when something started in the past and continues into the present. Asking "how often?" can also help you check if you're using the right tense.
Signal words
Examples
Present Perfect Progressive is used when an action started in the past and just finished or something has been happening for a certain period of time (how long?).
Signal words
Examples
Simple Past is used when an action was completed in the past and is not directly connected to the present.

Past Progressive is used when an on-going action in the past is disrupted by a shorter action or something was happening at a certain time in the past.
Signal words

Signal words
Examples
Past Perfect Progressive is used when describing how long something had been happening before another action took place or when comparing two past tenses, emphasizing on the duration.
Signal words
Examples
To emphasize an action, you can add "do" and its respective forms to a sentence.
Scheduled future actions (with certain verbs like to arrive, to end, to depart, to leave) can also be expressed through the Simple Present.
If a sentence converts strong emotions, the progressive form is used instead of the simple, even if there is a very clear signal word like always.
Certain verbs are rarely used in the ing-form. This is because these verbs describe a state, not an action or activity. Here are some examples:

Some verbs can be stative or action verbs, depending on the context.
