The present simple tense is one of the most common verb tenses in English. You use it every day to talk about habits, facts, and routines. If you are learning English at A1 or A2 level, mastering the present simple is your first big step toward clear communication. This guide covers every rule you need.
What is the Present Simple Tense?
The present simple tense describes actions that are regular, true, or permanent. You do not use it for actions happening right now. That is what present continuous is for.
Use the present simple tense for:
- Habits and routines: "I drink coffee every morning."
- Facts and general truths: "The sun rises in the east."
- Permanent states: "She lives in London."
- Scheduled events: "The train leaves at 6 pm."
- Feelings and opinions: "I like classical music."
Form 1: Affirmative Sentences
The structure is simple: subject + base verb. For he, she, and it, you add -s or -es to the verb.
| Subject | Verb Form | Example |
|---|---|---|
| I | base verb | I work in an office. |
| You | base verb | You speak English well. |
| We | base verb | We live in London. |
| They | base verb | They study at the library. |
| He / She / It | verb + -s/-es | She reads every day. |
Third Person Singular -s Rules
The most important rule in present simple is what happens with he, she, and it. The verb changes depending on its ending.
| Verb Ending | Rule | Example |
|---|---|---|
| -s, -sh, -ch, -x, -o | add -es | watch -> watches, go -> goes |
| consonant + y | change y to -ies | carry -> carries, fly -> flies |
| vowel + y | add -s | play -> plays, buy -> buys |
| most other endings | add -s | read -> reads, write -> writes |
More examples with he, she, it:
- He teaches English at the university.
- She studies every evening after work.
- It costs five dollars.
- He fixes cars for a living.
- She enjoys reading detective novels.
Form 2: Negative Sentences
To make a negative sentence, use do not (don't) or does not (doesn't) plus the base verb. Notice the verb goes back to its base form after doesn't.
| Subject | Negative Form | Contraction | Example |
|---|---|---|---|
| I | do not + verb | don't | I don't like cold weather. |
| You | do not + verb | don't | You don't need a visa. |
| We | do not + verb | don't | We don't work on Sundays. |
| They | do not + verb | don't | They don't speak Spanish. |
| He / She / It | does not + verb | doesn't | She doesn't eat meat. |
Common mistake: does not + -s
After "doesn't", the verb goes back to its base form. Do NOT add -s. "He doesn't works" is wrong. "He doesn't work" is correct.
Form 3: Question Forms
To form a question, use do or does at the beginning, followed by the subject and the base verb.
| Question Type | Structure | Example |
|---|---|---|
| Yes/No Question (I/you/we/they) | Do + subject + verb? | Do you like coffee? |
| Yes/No Question (he/she/it) | Does + subject + verb? | Does she speak French? |
| Wh- Question (I/you/we/they) | Wh + do + subject + verb? | Where do you live? |
| Wh- Question (he/she/it) | Wh + does + subject + verb? | When does the train leave? |
Short answers follow a pattern: Yes, subject + do/does or No, subject + don't/doesn't.
- "Do you like tea?" "Yes, I do." / "No, I don't."
- "Does he work here?" "Yes, he does." / "No, he doesn't."
Signal Words for Present Simple
Signal words help you decide when to use the present simple tense. If you see one of these words in a sentence, present simple is probably the right choice.
| Signal Word | Meaning | Example |
|---|---|---|
| always | 100% of the time | She always arrives on time. |
| usually | most of the time | We usually eat dinner at 7. |
| often | frequently | I often read before bed. |
| sometimes | 50% of the time | He sometimes works late. |
| rarely | not often | They rarely watch TV. |
| never | 0% of the time | I never drink coffee at night. |
| every day / week / year | regular interval | She walks her dog every morning. |
| on Mondays / at weekends | specific days | I play football on Saturdays. |
| once / twice a week | frequency | We meet once a week. |
| in the morning / evening | time of day | I study English in the evening. |
Common Mistakes with Present Simple
These are the most frequent errors English learners make with present simple. Avoid them to sound more natural.
| Mistake | Why It Is Wrong | Correct Version |
|---|---|---|
| He work in a bank. | Missing -s for he/she/it | He works in a bank. |
| She doesn't works here. | Verb keeps -s after doesn't | She doesn't work here. |
| Does he works? | Verb keeps -s after does | Does he work? |
| I am go to school. | Using am + verb instead of base verb | I go to school. |
| She go to the gym. | Missing -es for go (ends in -o) | She goes to the gym. |
| He studys every day. | Wrong -s rule for consonant + y | He studies every day. |
| They doesn't live here. | Using doesn't with they (plural) | They don't live here. |
| I am play tennis. | Using am with a main verb unnecessarily | I play tennis. |
Present Simple vs Present Continuous
English learners often confuse these two tenses. Here is the difference: present simple is for permanent situations and routines. Present continuous is for actions happening right now or around now.
| Use Case | Present Simple | Present Continuous |
|---|---|---|
| Habit vs right now | I drink coffee every day. | I am drinking coffee right now. |
| Permanent vs temporary | She lives in Paris. | She is living in a hotel this week. |
| General fact vs current action | Water boils at 100°C. | The water is boiling. Turn it off. |
| Signal word | always, usually, never | now, at the moment, today |

- Affirmative: I am tired. / She is a doctor. / They are happy.
- Negative: I am not tired. / She is not (isn't) a doctor. / They are not (aren't) happy.
- Question: Am I late? / Is she a doctor? / Are they happy?

Frequently Asked Questions
What is the present simple tense used for?
The present simple tense is used for habits, facts, routines, permanent situations, and scheduled events. For example: "I walk to work every day" (habit), "Water freezes at 0°C" (fact), "She lives in Berlin" (permanent situation).
When do you add -s or -es to verbs?
Add -s or -es to the verb when the subject is he, she, or it (third person singular). For most verbs, add -s (reads, writes). For verbs ending in -s, -sh, -ch, -x, or -o, add -es (watches, goes). For verbs ending in consonant + y, change y to -ies (carry becomes carries).
What is the difference between present simple and present continuous?
Present simple is for permanent situations and routines ("I work in an office"). Present continuous is for actions happening right now ("I am working on a report at the moment"). Signal words like "usually" and "every day" suggest present simple. Words like "now" and "at the moment" suggest present continuous.
How do you make questions in present simple?
Use "do" or "does" at the start of the sentence, followed by the subject and the base verb. For example: "Do you like tea?" and "Does she work here?" For wh- questions, put the question word first: "Where do you live?" and "When does the train leave?"
Is "to be" different from other verbs in present simple?
Yes. The verb "to be" (am, is, are) has its own rules. It does not use do/does for negatives or questions. For negatives, just add "not" after the verb: "I am not tired" (not "I do not be tired"). For questions, invert the subject and verb: "Is she ready?" (not "Does she be ready?").
What are signal words for present simple?
Common signal words include: always, usually, often, sometimes, rarely, never, every day, once a week, on Mondays, in the morning. These words describe how often something happens and are strong clues that present simple is the correct tense.
What are the most common mistakes with present simple?
The most common mistakes are: (1) forgetting to add -s for he/she/it ("He work" instead of "He works"), (2) keeping the -s after doesn't ("He doesn't works" instead of "He doesn't work"), (3) using "am" with main verbs ("I am go" instead of "I go"), and (4) confusing present simple with present continuous for permanent situations.
What level is present simple tense?
Present simple is typically taught at A1 (beginner) level on the CEFR scale. It is usually the first verb tense that English learners study. However, even advanced learners benefit from reviewing the third person -s rules and the difference between present simple and present continuous.
