The Present Simple Tense
The Present Simple (also called the simple present) is one of the most common tenses in English. We use it for habits and routines, facts and general truths, permanent situations, timetables, and states or feelings.
Rule of thumb: if something is generally true, regularly repeated, or a fixed fact, the Present Simple is usually the right choice.
Structure
For almost every verb, the Present Simple is just the base form of the verb — except with a third-person singular subject (he / she / it), where we add -s.
I / You / We / They work from home. → base form He / She / It works from home. → third-person singular adds -s The cat drinks water from the bowl. → subject is "the cat" She eats dinner at 9 p.m. → subject is "she"
Third-person spelling rules
Add -es (not -s) when the verb ends in -ch, -ss, -sh, -x, -zz or -o: watch → watches, kiss → kisses, wash → washes, go → goes, do → does.
Consonant + -y → change y to i and add -es: cry → cries, fly → flies, study → studies. But vowel + -y just takes -s: play → plays, say → says.
Negatives and questions
We use the auxiliary do / does for negatives and questions. Use does / doesn't with he / she / it, and do / don't with everything else. The main verb goes back to its base form (no -s).
I don't want to do my homework. → negative, base form My sister doesn't wake up early. → third person, no -s on "wake" Do they know each other? → yes/no question Where does Carolyn work? → wh- question
With he / she / it, the -s moves to the auxiliary — never double it. Say ~He doesn't works~ ✗ → He doesn't work ✓. And ~She go to school~ ✗ → She goes to school ✓.
The verb to be is irregular and needs no auxiliary — just add not or invert the verb:
I am a teacher. → I am not a teacher. → Am I a teacher? She is angry. → She isn't angry. → Is she angry?
When to use the Present Simple
1. Habits and routines
Things we do regularly, often with adverbs of frequency (always, usually, often, sometimes, rarely, never) or phrases like every day, twice a week, on Mondays.
I go to the gym three times a week. She always drinks tea in the morning. We usually work from home on Fridays. He never eats breakfast.
2. Facts and general truths
Things that are always true — laws of nature, science, widely known facts.
Water boils at 100°C. The sun rises in the east. Cats sleep about 15 hours a day. Kyiv stands on the Dnipro river.
3. Permanent situations
Long-term states — where you live, where you work, and so on.
He works as a software engineer. They live in Poland. She speaks three languages. I have two brothers.
For temporary situations, use the Present Continuous instead: I live in Kyiv (permanent) vs I'm living with my parents this month (temporary).
4. Timetables and schedules
Official schedules — transport, cinema, classes. Interestingly, the Present Simple is used here even for the future.
The train leaves at 6:45 tomorrow. The meeting starts at 10 a.m. The shop opens at 9 and closes at 9 p.m. My flight departs on Monday.
5. States, feelings, and opinions
With stative verbs — like, love, hate, know, believe, want, need, understand, remember — which are normally not used in the Continuous.
I love this song. She knows the answer. We need more time. I don't understand this rule.
6. Instructions and directions
First you open the app, then you click "Sign up". You take the second left and the office is on your right.
7. Zero / first conditionals and time clauses
After if, when, until, as soon as, we use the Present Simple to talk about general truths and the future.
If you heat ice, it melts. → zero conditional If it rains, we will cancel the trip. → first conditional I'll call you when I arrive. → future time clause
8. Narration, headlines, and commentary
Storytelling, sports commentary, jokes, plot summaries, and news headlines.
Messi passes the ball, and Ronaldo scores! The film tells the story of a young developer... Newspaper headline: President visits Ukraine.
Quick review
Present Simple = base form for I/you/we/they, + -s for he/she/it. Use do/does for negatives and questions (main verb loses the -s). Reach for it for habits, facts, permanent states, timetables, feelings, and after if/when.
Which sentence correctly uses the Present Simple? [ ] She go to school every day. [x] He does his homework in the evening. [ ] He plaies basketball on Sundays. [ ] She studyes at the library every morning. > With "she/he" we add -s to the base verb, and the spelling must follow the rules: plays (vowel + y), studies (consonant + y → -ies). "He does his homework" is correct.
Choose the correct first-conditional sentence. [ ] If he leave early, he will catches the bus. [ ] If he will leave early, he catches the bus. [x] If he leaves early, he will catch the bus. [ ] If he leave early, he catch the bus. > First conditional = if + Present Simple, then will + base verb. The if-clause never uses "will".
Pick the correct negative. [ ] My brother don't eats vegetables. [x] My brother doesn't eat vegetables. [ ] My brother doesn't eats vegetables. [ ] My brother not eat vegetables. > Third-person negative uses "doesn't" + the base form, so the -s disappears from the main verb.
