Verbs come in three tenses: past, present, future. The past is used to describe things that have already happened (e.g. earlier in the day, yesterday, last week, three years ago). The present tense is used to describe things that are happening right now, or things that are continuous. The future tense describes things that have yet to happen (e.g. later, tomorrow, next week, next year, three years from now).
The simple present tense is the one which we use when an action is happening right now, or when it happens regularly (or unceasingly, which is why it’s sometimes called present indefinite). The simple present tense is formed by using the root form or by adding ‑s or ‑es to the end, depending on the person.
Regular Verbs
In present tense, regular verbs use the root form, except for third person singular (which ends in ‑s).
First person singular: I write
Second person singular: You write
The simple past refers to things that have already happened, and are finished doing their thing.

The simple future is a verb tense that’s used to talk about things that haven’t happened yet.

Use the simple future to talk about an action or condition that will begin and end in the future.
