What the Present Simple Is
The present simple talks about things that happen regularly, about habits, and about things that are always true. Going to work every day, coffee every morning, or water boiling at 100°C.
HABITEvery morning
Monday to Friday, every one of them.
I drink coffee every morning.
Yesterday, today, tomorrow — the same thing happens again.
ALWAYS TRUEA fact, not a moment
It was true yesterday, it is true today, it will be true tomorrow.
Water boils at 100°C.
True yesterday, true today, true tomorrow.
TRY IT
- Question 1
"I coffee every morning."
- Question 2
"My dad to work every day."
The three forms
POSITIVE
SV (s/es)
She works in Hà Nội.
Her job, not what she is doing right now.
NEGATIVE
Sdo / doesnotV
She doesn't work on Sundays.
Sunday is her day off, every Sunday.
QUESTION
Do / DoesSV?
Does she work here?
Asking about the general situation.
THE -S/-ES AT A GLANCE
- workworks
- playplays
- gogoes
- watchwatches
- studystudies
-o, -ch, -sh, -x, -ss → +es · consonant + y → -ies
In the positive it sits on the main verb (she works). In the negative and the question, does is already carrying it, so the main verb drops back to its base form: she doesn't work, does she work?
TRY IT
- Question 1
"She to school every day."
- Question 2
"He like coffee."
- Question 3
" they live in Hà Nội?"
Short answers use the auxiliary, not the verb
An English Yes/No answer is not just yes or no — it is yes or no plus a subject plus the auxiliary that opened the question. Answering with the main verb sounds wrong even when every word is a real English word.
| QUESTIONS WITH DO | QUESTIONS WITH DOES | |
|---|---|---|
| Question | Do you speak English? | Does she speak English? |
| Yes | Yes, I do. | Yes, she does. |
| No | No, I don't. | No, she doesn't. |
| Never say | Yes, I speak. | Yes, she speaks. |
| Adding more | Yes, I do. I speak a little. | No, she doesn't. She speaks French. |
The last row is how real conversation goes: the short answer settles the question, and then a full sentence adds the detail. And once you are back in a full sentence, the ordinary rules return — she speaks French has its -s again, because there is no auxiliary in that sentence to hold it.
When to use it
Habits
I drink coffee every morning.
True yesterday, true today, true tomorrow.
Signal words: every day · usually · often · always
Facts
Water boils at 100°C.
True whenever you say it.
Signal words: facts · rules · things that are always true
Timetables
The train leaves at 7 a.m.
The time is fixed, so even tomorrow's train takes the present simple.
Signal words: schedule · timetable · fixed times
Feelings and states
I love this song.
A state, not an action — so never “I am loving this song”.
Signal words: love · know · want · believe

Quick check · 7 questions
Choose the correct form:
My father works in a hospital.
- A. work
- B. works — Correct
- C. working
Answer: B. works
A single person as subject means the verb takes -s. This ending exists nowhere else in the present simple, which is why it is so easy to leave off.
Choose the correct form:
We study English on Mondays.
- A. study — Correct
- B. studies
Answer: A. study
We is not one of the three, so the verb keeps its base form. The -s belongs to a single person or thing and to nothing else.
Choose the correct spelling:
My sister studies English at home.
- A. study
- B. studys
- C. studies — Correct
Answer: C. studies
My sister is she, so the ending is needed, and the d in front of the y makes it -ies. Studys is a spelling error rather than an alternative.
Choose the correct negative:
He doesn't eat meat.
- A. doesn't eat — Correct
- B. doesn't eats
- C. don't eats
Answer: A. doesn't eat
Doesn't is already carrying it, so the main verb goes back to eat. And he takes doesn't rather than don't.
Choose the correct word:
They don't live here.
- A. don't — Correct
- B. doesn't
Answer: A. don't
Doesn't belongs to he, she and it. Everything else — I, you, we, they — takes don't.
Choose the word that starts the question:
Does your mother cook every day?
- A. Does — Correct
- B. Do
- C. Is
Answer: A. Does
Cook is an ordinary verb, so the question borrows does rather than a form of be.
Choose the correct short answer:
"Do you speak English?" — "Yes, I do."
- A. I do — Correct
- B. I speak
- C. I am
Answer: A. I do
A question that opens with Do is answered with do. Repeating the main verb instead is the commonest way a short answer goes wrong.
