English Negatives
How to say no in English: don’t, doesn’t, isn’t, never — and when to use which. The essentials take about two minutes; extra details are tucked away at the bottom.
Saying No
Four ways to say no
A negative sentence says no. "I like coffee" — now take the no away: "I don’t like coffee". English has a few ways to say no, and they all follow small, friendly rules.
don’t / doesn’t
For actions and habitsI don’t like coffee
isn’t / aren’t
For be — no helper neededShe isn’t happy
never
Zero times — everI never smoke
no
A short answer — no!Do you like coffee? — No.
The Formula
Three ways to put the no
One helper does the work: do/does + not, placed between the subject and the verb. Be skips the helper — not sticks to be itself. And never needs no helper at all.

Common Mistakes
Don’t put the no in the wrong spot
Three places where the no goes wrong: the wrong helper, the double no, and be with do. Fix these four and you are safe.
I no like coffee.
I don’t like coffee.
💡 No is not a verb helper. With an action, use don’t: I don’t like coffee.
She don’t like tea.
She doesn’t like tea.
💡 With he/she/it, the helper is doesn’t.
I don’t never smoke.
I never smoke.
💡 One no per sentence is enough — never already says no.
He doesn’t is here.
He isn’t here.
💡 Be does not need do/does: is + not → isn’t.

No vs Not
One no for things, one no for verbs
No stands alone or before a noun. Not goes with a verb — it never stands alone.
Short Forms
don’t = do + not
Written English loves the short forms. The apostrophe marks the missing letter — no space, no excuse.
don’t = do + not
One word, no space
do not → don’t · I don’t know
doesn’t = does + not
Same, for he/she/it
does not → doesn’t · She doesn’t work
isn’t / aren’t = be + not
The be short forms
is not → isn’t · are not → aren’t
never stays never
Already short — no changes
never · never · never
⚠️ One no per sentence is enough — never already means not.
