What is the Present Simple Tense?
The Present Simple tense is the absolute foundation of the English language. Despite its name, it does not necessarily describe something happening right now in this exact second (that is the Present Continuous). Instead, the Present Simple expresses things that are regularly true, permanently true, or habitual.
It communicates: "This is what I generally do. This is what is scientifically true. This is what officially happens."
Present Simple Tense Structure and Formula
How to Form the Present Simple: Positive Sentences
The primary rule is that the verb remains in its base form for most subjects. The only massive exception is the third person singular (he, she, it), which requires an ending.
Formula: Subject + Base Verb (+ s/es) + Object
(S + V/V-s/es + O)
| Subject (S) | Verb Form | Example Sentence |
|---|---|---|
| I / You / We / They | Base Verb (V) | I work every day. |
| He / She / It | Base Verb + -s / -es | He works every day. |
Spelling Rules for "He / She / It" Verbs:
| Grammar Rule | Base Form | He/She/It Form |
|---|---|---|
| Most verbs: Just add -s | play, read | plays, reads |
| Ends in -s/sh/ch/x/z/o: Add -es | pass, watch, go | passes, watches, goes |
| Consonant + y: Change 'y' to -ies | study, carry | studies, carries |
| Vowel + y: Just add -s | play, buy | plays, buys |
| The massive irregulars | have, be | has, is |
How to Form the Present Simple: Negative Sentences
Use do not (don't) or does not (doesn't) before the base verb.
Formula: Subject + don't/doesn't + Base Verb + Object
(S + do/does not + V + O)
| Subject | Auxiliary Negative | Base Verb (V) | Example |
|---|---|---|---|
| I / You / We / They | don't | base form | I don't like coffee. |
| He / She / It | doesn't | base form | She doesn't work here. |
Instructor Tip: The main action verb never ever takes an -s ending in negative sentences. The auxiliary doesn't already swallowed the "s". (She doesn't works is fatal).
How to Form the Present Simple: Questions and Short Answers
Place the auxiliary do/does before the subject.
Formula: Do/Does + Subject + Base Verb?
(Do/Does + S + V + O?)
| Auxiliary | Subject (S) | Base Verb (V) | ? |
|---|---|---|---|
| Do | I / you / we / they | live | Do you live here? |
| Does | he / she / it | work | Does she work late? |
Wh- Questions Formula: Wh- word + do/does + S + V?
Where do you live?
Why does he study so late?
When to Use the Present Simple Tense in English
1. Habits, Routines, and Frequencies
This is the most common usage. It describes things that happen daily, weekly, or at a consistent interval.
I get up at seven every morning.
She goes to the gym three times a week.
He never eats fast food.
2. Permanent Facts and General States
Things that are permanently true for a long period of time (residences, abilities, truths).

She lives in London.
I speak Vietnamese and English.
3. Fixed Timetables and Official Schedules
If you are talking about a bus, train, or a movie that operates on an official, printed timetable, use Present Simple (even if the event happens in the future!)
The train leaves at 8:15 tomorrow.
The film starts at 9 p.m.
4. Giving Step-by-step Instructions
First, you open the app. Then you enter your username.
You turn left at the traffic lights.
Common Signal Words and Time Expressions
| Signal Word / Expression | Placement | Example Sentence |

| sometimes / rarely / never | Before main verb | He never drinks alcohol. |
| every day / every week | End of sentence | I go to the gym every day. |
How to Tell the Difference: Present Simple vs. Present Continuous
| Feature | Present Simple (S + V) | Present Continuous (am/is/are + V-ing) |
|---|---|---|
| What it describes | Deeply engrained habits or permanent facts. | Actions happening right now or temporarily. |
| Example (Routine) | She works in a hospital. (Permanent Job) | She is working late tonight. (Only tonight) |
| Example (General) | I live in Hanoi. (Permanently) | I am living in Hanoi. (Temporarily testing it out) |
Frequently Asked Questions
Can I ask a question with "Who" without using "does"?
Yes! If the word "Who" is functioning as the subject of the sentence, you skip the "do/does" completely and just slap the verb right on it.
Who lives next door? (Correct)
Who does live next door? (Incorrect)
Do I add "s" to the verb if there are two subjects?
No. If there are two subjects (e.g. John and Mary), the subject grammatically becomes "They" (plural). Therefore, you use the base verb.
John and Mary work together. (Not: works)
Are there any verbs that CANNOT be used in the -ing continuous form?
Yes! They are called Stative Verbs. These describe mental states, senses, or emotions. They must ALWAYS stay in the Present Simple, even if you are feeling it right now.
I know the answer. (Not: I am knowing).
I want coffee. (Not: I am wanting).
