Present Simple
The present that doesn't mean “now”
GoalBy the end you will know why English has two present tenses, which one each sentence needs, where the -s and the auxiliary do come from, and you will have used it out loud.
The problem
English has two present tenses: one for routines and what is true in general, one for what is happening right now. Every time you talk about the present, you have to choose.
I work.
I am working.
The main idea
The present simple isn’t about this moment. It is about what is true in general: routines, permanent facts, how the world works — your whole life, not this second.
I drink coffee every morning.
She lives in Sydney.
Water boils at 100°C.
None of the three has to be happening right now. All three are still true.
Try it — simple or continuous?
Compare the two
Same person, same verb, same day — two different meanings:
He works at a bank.
He is working right now.
The classic mistake
I am working here every day.
I work here every day.
“Every day” points to a routine, not to this moment. Something repeated or permanent doesn’t take the continuous.
How it's built
Subjectbase form of the verb
I work · you work · we work · they work
Four persons, one single form.
The one exception: the third person singular takes -s. It is a fossil — all that is left of the verb endings English lost centuries ago. It adds no meaning, which is why people forget it so often.
He / She / Itverbs
How to spell that -s:
| Case | Rule | Example |
|---|---|---|
| Most verbs | Add -s | work → works |
| Ends in -ch, -sh, -ss, -x, -o | Add -es | watch → watches |
| Consonant + y | Change y → ies | study → studies |
| Vowel + y | Just add -s | play → plays |
Decide two things at once: whether the subject takes -s, and how to spell it.
The auxiliary and the negative
The main verb can’t make a negative or move on its own: it needs do / does, which carries the tense and the person, leaving the main verb in its base form.
He workSHe doeS not work
Subjectdon't / doesn'tbase verb
| Subject | Auxiliary | Example |
|---|---|---|
| I / You / We / They | don’t | I don’t work here. |
| He / She / It | doesn’t | He doesn’t work here. |
Questions
English doesn’t make a question with intonation alone: it moves the auxiliary to the front, and only the auxiliary can move.
Do / Doessubjectbase verb?
You work here.
Do you work here?
So the question isn’t “You work here?” said with a rising voice: with no auxiliary, there is nothing to move to the front.
Common mistake
He don't works here.
He doesn't work here.
Two mistakes in four words, both the same: the person is marked only once. If does has it, the verb is in its base form.
Questions with where, what, when and how
To ask where, what, when or how, the question word goes first — and the auxiliary is still there, right after it:
Wh-do / doessubjectbase verb?
Where do you live?
Wheredo
What does she study?
Whatdoes
When do you travel?
Whendo
How does he cook his food?
Howdoes
The typical mistake is to leave the auxiliary out:
Common mistake
Where you live?
Where do you live?
Where is not an auxiliary: it can’t do the auxiliary’s job. The question still needs do.
The exception: who
Who does live here?
Who lives here?
When who asks about the subject, the auxiliary disappears — the only case where it does. who takes the subject’s place, so the verb takes the -s itself — Who lives here?, Who works on Saturdays?
