Simple Present with Other Verbs
For all verbs except to be, we use the base form of the verb in the present simple. For he / she / it, we add -s or -es to the verb. For questions and negatives, we use do or does as an auxiliary.
Positive: I / You / We / They + base verb | He / She / It + verb + -s / -es
Negative: subject + don't / doesn't + base verb
Question: Do / Does + subject + base verb?
Positive Sentences
I work in a hospital.
She studies English every day. (+es after consonant + y → ies)
He watches TV in the evening. (+es after ch, sh, x, o, s)
They live in London.
Negative Sentences
Use don't (I/you/we/they) or doesn't (he/she/it) + base verb. The main verb never takes -s in the negative.
I don't like coffee.
She doesn't work on Sundays.
They don't speak French.
Questions
Use Do or Does at the start of the question. The main verb stays in the base form.
Do you like pizza?
Does he play football?
Where do they live?

✗ She don't like it. → ✓ She doesn't like it.
✗ Does he works here? → ✓ Does he work here? (no -s after does)
✗ He don't speaks English. → ✓ He doesn't speak English.
