Present Simple in English: Affirmative, Negative, and Questions (Full Guide)
The tense for habits, routines, and general facts, with the rule almost everyone forgets: the -s on he/she/it.
Written by Bryan López, Profesor de inglés · Updated
The Present Simple is used for habits, routines, and general facts: I work every day, Water boils at 100°C. The key rule is that he/she/it add an -s to the verb (she works), while I/you/we/they use the verb unchanged (I work).

What the Present Simple is used for
It's used for habits and routines (I go to the gym every day), general facts or truths (Water boils at 100°C), and fixed schedules (The train leaves at 6pm). It's not used for something happening right now, that's what the Present Continuous is for.
Common mistakes with Present Simple
Forgetting the -s in the third person. It's the single most common mistake: saying "She work" instead of "She works." Many languages don't mark the third person as strictly across all verbs, so it's easy to forget in English. Adding -s to the verb after does. "Does she works?" is wrong, because "does" already carries the third-person marker; the main verb stays in its base form: "Does she work?" Using don't with he/she/it. "She don't work" is incorrect, with he/she/it it's always doesn't: "She doesn't work."

Time expressions and adverbs
The Present Simple usually appears with words that show repetition: every day, every week, on Mondays, in the morning, always, usually, often, sometimes, rarely, and never. "I go to the gym on Mondays." "She usually drinks tea in the evening." These clues tell you a habit or routine is being described, not something happening right now.
Do and does in questions and negatives
Facts, schedules, and opinions
The Present Simple also describes general truths ("Water boils at 100 degrees"), timetables ("The train leaves at 8:15"), and permanent states like opinions and feelings ("I like this song"). This is why the tense is so common: it is the basic tense for facts, routines, and states. When you are unsure which present tense to use, ask yourself if the idea is always true or repeated. If yes, use the Present Simple.
Examples of Present Simple
- My brother works in a hospital.
- We don't have classes on Friday.
- Does your mother cook every day?
- The sun rises in the east.
- She studies English at night.
The missing -s
Incorrect
She work in a bank.
Correct
She works in a bank.
Present Simple in a real conversation
A: "What do you do on weekends?" B: "I usually sleep late, and then I meet my friends." A: "Do they live nearby?" B: "Yes, most of them live in my neighborhood, but one lives in another city."
Stative verbs are always simple
Verbs that describe states, such as know, like, love, hate, want, and need, almost always use the Present Simple, even when the situation is happening now. "I love this song" is correct, and "I'm loving this song" is not standard in normal use. The same goes for "She knows the answer" or "They need help." This is a good rule of thumb for deciding between the simple and the continuous.
Frequently asked questions
When is the Present Simple used?
For habits and routines (I study every day), general facts (The sun rises in the east), and fixed schedules (The store opens at 9am).
What is the rule for the third person (he/she/it)?
You add -s or -es to the verb: he works, she watches, it goes. It's the only subject that changes the verb form in the affirmative.
When do you use does instead of do?
Does is used with he, she, it (third-person singular). Do is used with I, you, we, they.
How do you make the Present Simple negative?
With don't + base verb for I/you/we/they, and doesn't + base verb for he/she/it: I don't like coffee, she doesn't like coffee.
How do you ask questions in the Present Simple?
By putting do or does at the front: Do you like coffee? Does she like coffee? The main verb always stays in its base form.
Why do you say "Does she work?" and not "Does she works?"
Because "does" already carries the third-person marker. The main verb never takes -s once there's already a do/does earlier in the question or negative.
Why does the verb take -s with he, she, and it?
It is a historical rule of English: only the third person singular takes -s in the Present Simple. It is one of the few verb endings left in the language, and it is the one learners forget most.
Which verbs take -es?
Verbs that end in -s, -sh, -ch, -x, -z, and -o: watch becomes watches, go becomes goes, fix becomes fixes. Verbs ending in consonant + y change to -ies: study becomes studies.
Do I use does and -s together?
No. After does or doesn't, the main verb stays in the base form: "Does she work?" not "Does she works?" The -s already appears in does.
