Answer in brief
The present simple describes habits and routines, general truths, timetables and states: I work, she works, the train leaves at six. It uses the base form of the verb, adds -s or -es after he, she and it, and needs do or does for negatives and questions, where the main verb loses its ending: she doesn’t work, does she work?
What the present simple expresses and how it is built
The present simple is the English tense for habits and routines, general truths, timetables and states. It uses the base form of the verb, as in I work or they live, and adds -s or -es only after he, she and it: she works. Negatives and questions take the helper do or does, and the main verb returns to its base form: she doesn’t work, does she work? British Council’s LearnEnglish places this grammar at levels A1 and A2.
The name can mislead: the tense is mostly about what is regular, not this very second. Purdue University’s Online Writing Lab gives compact examples: I run on Tuesdays and Sundays for a habit, There are thirty days in September for a general truth, I like music for a state, and The train leaves at 4:00 p.m. for a future event fixed by a schedule. What is happening right now usually needs another tense, the present continuous.
Affirmative sentences: the base form and the he, she, it ending
With I, you, we and they, the verb stays as it is; Wikipedia’s article on the simple present says these pronouns bring no change. Everything happens with he, she, it or any single person or thing in their place: my brother, the shop. The same article lists the spelling rules. Verbs ending in -o, -ch, -sh, -s, -x or -z add -es: goes, catches, washes, fixes. A consonant plus y turns into -ies, as in studies or worries, while a vowel keeps the y: plays, enjoys.
British Council adds that have, do and go are irregular with he, she and it, as in He has a flat in the city centre and My dog goes for a walk every morning. The ending is also pronounced three ways, described in Wikipedia’s article on English verbs: /ɪz/ after sibilants, as in watches, /s/ after other voiceless consonants, as in makes, and /z/ elsewhere, as in adds or plays. Does and says look regular but sound otherwise, /dʌz/ and /sɛz/. The verb be keeps its own forms, am, is and are, and modals such as can and must take no ending.
Negatives and questions with do and does, plus short answers
For a negative, English puts the helper do before not: I do not write, he does not write, as Wikipedia shows, shortened in speech to don’t and doesn’t. The same helper opens a yes-no question, as in British Council’s Do you watch a lot of films? and Does he speak English? Grammarians call this do-support, and Wikipedia’s article on it describes the verb after the helper as a bare infinitive that does not inflect. That is why the -s moves: she works, but she doesn’t work and does she work?
Short answers repeat the helper, as British Council lists them: Yes, I do, Yes, he does, No, she doesn’t. Question words go in front of do or does: Where do you work? How often do you see your parents? The rule holds when do is the main verb too, so She does yoga becomes Does she do yoga? The verb be needs no helper at all, since the do-support article says it is not used when an auxiliary or the copula is already present: Are you ready?, never Do you are ready?
When the simple present is used: routines, facts and timetables
The first and widest use covers anything regular. British Council’s grammar reference gives I play football every weekend. The second use is a situation true now and expected to last: He lives in London. The third is a general truth, which the same reference illustrates with Light travels at almost 300,000 kilometres per second. It also tells stories and commentary: British Council sums up a book with Harry Potter goes to Hogwarts School, and Wikipedia quotes the sports line Ronaldo dribbles around the defender and shoots.
A fixed timetable can point to the future without any future form. British Council’s examples are The train leaves at 19.45 this evening and The school term starts next week, and Wikipedia adds Our holiday starts on 20 May. The tense also replaces the future after when, before, after, if and unless: I’ll talk to John when I see him, If it rains we’ll get wet. British Council is explicit that the present simple belongs there even with a future meaning: when I see him, not when I will see him.
Always, usually, never: where adverbs of frequency go
Habits come with words that say how often. British Council’s page How often lists the commonest: always, never, normally, rarely, seldom, sometimes, occasionally, often and usually. Their position follows one rule with one exception. A one-word adverb normally stands in front of the main verb, as in the page’s We often spend Christmas with friends. After the verb be it moves to the other side: We are never late for work.
Longer expressions behave differently. The same page puts a lot at the end of the clause, We go to the cinema a lot, and its examples with every and twice close the sentence too: We have a meeting every Monday, I go swimming twice a week. Frequency questions open with How often, and ever sits before the main verb: Do you ever go to the cinema at the weekend? So it is I often go to the gym, not I go often to the gym.
Usually or right now: the line with the present continuous
The present continuous is built from am, is or are plus the -ing form. British Council’s reference uses it for activities at the moment of speaking, I’m just leaving work, and for temporary situations, He’s studying history. Purdue’s table makes the contrast visible: its activity in progress is I am playing soccer now, while its habit is the run on Tuesdays and Sundays quoted above. A quick test helps: if usually or every week fits the sentence, choose the simple form; if right now or these days fits better, the continuous probably does.
Verbs of state stay on the simple side. British Council’s page on stative verbs, written for levels B1 and B2, sets I don’t know the answer against the incorrect I’m not knowing the answer. The same page shows verbs that work both ways: I think it’s a good idea is an opinion, while I’m thinking is the mental activity; I have an old car is possession, I’m having a quick break an activity. The full map of English tenses is a separate lesson.
Typical present simple mistakes, corrected one by one
The first slip is the missing ending: She work in a bank instead of She works in a bank. The ending is short in speech, so the fix is to check every he, she or it sentence on paper. The second is the opposite, the ending written twice: Does he goes?, He doesn’t works. After does or doesn’t, the verb stays bare: Does he go? He doesn’t work. The third blends two patterns, I am work: am, is and are belong to be and to the continuous, so the sentence needs either I work or I am working, not half of each.
The fourth is a question carried only by a rising voice: You like coffee? Wikipedia’s article on yes-no questions notes that in Russian, intonation alone can turn a statement into a question; written English still expects Do you like coffee?, and Where you live? needs its helper too. Other slips come from the first language. Spanish, as Wikipedia’s article on null-subject languages explains, does not require the subject pronoun, which leads to Works in a bank. Spanish and French give age with the verb for have, as Wiktionary shows with Tengo veinte años and Elle a 19 ans, and that becomes I have twenty years instead of I am twenty.
A week of present simple practice alone, and what the course adds
A week alone makes the rules automatic if the exercises are concrete. On day one, write ten true sentences about your routine with I. On day two, rewrite them about a friend with he or she and underline each ending. On day three, turn every sentence into a negative and a question with a short answer. On day four, add always, usually or never and check their position; on day five, write your week’s timetable with leaves and starts; on the last two days, read everything aloud and hunt for the slips above.
A structured course adds order and return. In VITON13 SCHOOL’s online course English in 113 Days, the present simple is spread over several levels: 12 covers I, you, we and they, 13 adds he, she, it and the -s, 15 brings do and does, 16 adds like with -ing and adverbs of frequency, 20 reviews A1, 22 sets it against the present continuous and 50 returns to it in the passive. Each daily level brings 13 new words with sound, transcription and an example, a three-minute grammar point with the mistake speakers of your language usually make, and dictation; the FSRS spaced-repetition algorithm brings words back as they start to fade. Explanations come in Russian, French, Spanish, German or Portuguese, chosen in the classroom; the first three levels open without payment or sign-in, and a free placement test shows where to start.
Practical checklist
- Write ten sentences about your routine with I, then rewrite them about a friend with he or she.
- Check every he, she or it verb for its ending, using the -es and -ies spelling rules.
- Turn each sentence into a negative with don’t or doesn’t and a question with do or does.
- Put always, usually, sometimes or never before the main verb and after am, is or are.
- Read your sentences aloud and sort each ending by sound into /s/, /z/ or /ɪz/.
Questions and answers
When do you add -es instead of -s in the present simple?
After verbs ending in -o, -ch, -sh, -s, -x or -z: goes, watches, washes, misses, fixes, buzzes. If a consonant comes before a final y, the y becomes -ies, as in studies or carries; after a vowel it stays, as in plays or says. Have is irregular and becomes has.
Are am, is and are part of the present simple tense?
Yes, as the forms of the verb be: I am tired, she is a teacher, they are at home. With any other verb, English uses the plain form or the -s form with no am, is or are, so it is I work, not I am work. Questions with be need no do: Is she ready?
Why is it does he work and not does he works?
Because does already shows both the present tense and the third person. Once the helper is there, the main verb goes back to its dictionary form, so the ending is never written twice. Negatives follow the same logic: he doesn’t work, she doesn’t live here.
Can the present simple talk about the future?
For fixed timetables and schedules, yes: the bus leaves at seven, the term starts on Monday. It is also the normal choice after when, before, after, if and unless when the meaning is future: call me when you arrive, not when you will arrive.
Which English verbs are not used in the continuous form?
State verbs such as know, like, want, believe, understand, own and belong usually stay simple: I know, not I am knowing. A few change meaning in the continuous, for example have for possession versus having for an activity, or think as an opinion versus thinking as a process.
