Grammar

No or not?

No and not are the two most common words we use to indicate negation. We use no before a noun phrase: …

Not

Not is one of the most common words we use to indicate negation. It is often shortened to n’t and joined to an auxiliary verb or modal verb: …

Not in negative statements (She hasn’t …, I did not …)

We form negative declarative clauses with not after be (she is not talking), after modal verbs (they must not go) and after auxiliary verbs do and have (we did not like it; they have not eaten). …

Not and n’t in questions (Did younot …? Wasn’t she …?)

We use not or n’t to form negative questions: …

Don’t, Do not: orders and instructions

We use don’t + the base form of the verb or do + not + the base form of the verb to make negative imperatives. We use these to give orders, instructions or commands. Do not is stronger and much more formal: …

Not: short replies

We use not in negative short replies with mental process verbs (e.g. be afraid, guess, hope): …

Not: contrast

We often use not after but to express a contrast. We often leave out the verb phrase or part of it in the second clause: …

Not + -ing and not + to

We use not before an -ing clause in more formal styles: …

Or not

We can use or not in questions to ask about a range of possibilities: …

So and not with expect, hope, think, etc.

We can use so after some verbs instead of repeating an object clause, especially in short answers. The verbs we do this with most are: appear, assume, be afraid (meaning ‘regret’), believe, expect, guess, hope, imagine, presume, reckon, seem, suppose, think: …
