Present Simple: Rules, Examples and Common Mistakes
The present simple is the tense you need most: habits, routines, facts and timetables. It looks like the easiest tense in English, and that is exactly why learners stop checking it too early. This guide gives you the rules on one screen, the spelling you have to get right, the questions and negatives that decide most exam marks, and the mistakes that keep appearing in real writing.
Present simple: form at a glance
| Subject | Verb form | Example |
|---|---|---|
| I / you / we / they | base verb | They live in Dubai. |
| he / she / it | base verb + -s | She works from home. |
| any subject | do / does + not + base verb | He doesn't drive. |
| any subject | Do / Does + subject + base verb? | Do you speak Spanish? |
| any subject | am / is / are | The bus is late. |
When to use the present simple
Use the present simple for anything that is true in general rather than true right now. That covers five everyday situations:
- Habits and routines — things you do again and again: I drink coffee every morning. She walks to work.
- Facts and general truths — things that do not change quickly: Water boils at 100 degrees. The Earth goes round the Sun.
- Permanent situations — jobs, homes, states: He works for a bank. We live in Manchester.
- Timetables and schedules — fixed events in the future: The train leaves at 6.15. The film starts at nine.
- Feelings, opinions and thoughts — with verbs like like, know, want, believe, mean: I love this song. She doesn't understand the question.
The test is simple: if you can add every day, usually, normally or always without changing the meaning, you want the present simple.
The third person -s (the biggest spelling trap)
With he, she, it the verb takes an -s. That tiny letter is worth more exam marks than any other rule in this guide, so learn the four spellings:
- Add -s to most verbs: work → works, live → lives, play → plays.
- Add -es after -s, -sh, -ch, -x and -o: kiss → kisses, wash → washes, watch → watches, fix → fixes, go → goes, do → does.
- Change consonant + y to -ies: study → studies, carry → carries, fly → flies. Vowel + y keeps the y: play → plays, buy → buys.
- Irregular forms: have → has, be → is, and be never takes do: She is a nurse, not she does be.
Pronunciation matters too: the -s sounds like /s/ after p, t, k, f (stops, hits, looks), like /z/ after a vowel or voiced sound (plays, needs), and adds a syllable /ɪz/ after s, z, sh, ch, x, ge (kisses, watches, changes).
Negatives, questions and short answers
To build a negative, put do not or does not before the base verb. In questions, put do or does in front of the subject. The verb itself never changes in either case — the -s moves onto does.
He works here. → He doesn't work here. → Does he work here?
After do or does, add the base verb only: Does she like jazz? not does she likes. Short answers repeat the auxiliary, never the main verb: Yes, I do. No, she doesn't. With a question word, the auxiliary keeps its place: Where do you live? Why does he want the report today?
One more trap: be does not use do at all. Are you tired? and She isn't here — never do you be or she doesn't be.
Present simple or present continuous?
The two tenses divide the world in half. Use the present simple for what is generally true (She works in a bank) and the present continuous for what is happening now or around now (She is working from home this week). Time expressions usually tell you which one you need: every day, usually, never point to the simple; now, at the moment, today, this week point to the continuous.
State verbs such as know, want, like, believe, understand, own and need stay in the simple form even when you mean right now: I know the answer, never I am knowing. There is a full comparison, with the pairs learners mix up most, in our present simple vs present continuous guide.
The mistakes learners make most often
Almost every wrong sentence in this area is one of the five below. Read the pair out loud — the wrong version then the right one — and the contrast does the teaching.
✘ He don't like coffee. → ✔ He doesn't like coffee.
Third person singular subjects take does, so the negative is doesn't, not don't.
✘ Does she likes jazz? → ✔ Does she like jazz?
The -s belongs to does. After do or does, the main verb always returns to its base form.
✘ I am knowing the answer. → ✔ I know the answer.
Know is a state verb: it describes a state, not an activity, so it is not used in the continuous form.
✘ She always eat breakfast at seven. → ✔ She always eats breakfast at seven.
Words like always, usually and never change nothing about the verb ending: he / she / it still needs -s.
✘ I have 25 years. → ✔ I am 25 years old.
English uses be for age. Have describes possession or experience, not how old somebody is.
How to practise the present simple
Rules are remembered in the head and learned in the hands. Five minutes of retrieval practice beats half an hour of re-reading, because the point is to make doesn't and -s automatic before you speak.

Frequently asked questions
When do we use the present simple?
Use the present simple for habits and routines (I drink coffee every morning), facts and general truths (Water boils at 100 degrees), permanent situations (He works for a bank) and timetables (The train leaves at 6.15). It describes what is generally true, not what is happening at this second.
How do I spell the third person singular?
Add -s to most verbs (work → works). Add -es after s, sh, ch, x and o (watch → watches, go → goes). Change consonant + y to -ies (study → studies). Have becomes has, and be becomes is. After do or does in questions and negatives, the main verb goes back to its base form.
Why is he doesn't likes wrong?
Because the -s has already been used on does. English marks the third person singular once, on the auxiliary: He doesn't like jazz. Does she like jazz? The same rule applies to questions with a question word: Where does he live?
What is the difference between the present simple and the present continuous?
The present simple describes what is generally true or repeated: I work in London. The present continuous describes what is happening now or around now: I am working from home this week. State verbs like know, want and believe stay in the simple form even when they refer to the present moment.
