Negative: don't / doesn't
Add don't or doesn't before the base verb. The verb does NOT take -s in the negative:
| Pronoun | Auxiliary | Example |
|---|---|---|
| I / You / We / They | don't (do not) | I don't like coffee. · They don't work here. |
| He / She / It | doesn't (does not) | She doesn't like coffee. · He doesn't work here. |
No -s in the negative:
"She doesn't likes coffee" ✗ → "She doesn't like coffee" ✓. The -s moves from the verb to the auxiliary: she works → she doesn't work.
Questions: Do / Does

| Subject | Auxiliary | Example |
