Negation: Verbs & Clauses
Negation is the process that turns an affirmative statement into a negative one. In this lesson, we will learn about ways of creating negative sentences.
What Is Negation?
Negation is a grammatical notion that refers to the process of turning an affirmative statement into a negative one. Negation can happen in a number of structures.
Negation with NOT
The most common way to negate a statements is by using 'not' or n’t after verbs.
n’t is the contracted form of not. There is no space between the verb and n’t.
Be + Not
'Be' is one of the most common verbs in the English language, so it seems logical that we start by learning how to negate it.
|Be||Be in Negative|
As you can see from the table above, the verb 'be' in the first person form 'am' cannot be written in the contracted form. So, never write
With is and are there are two possible negative statements, ’s not or isn’t and ’re not or aren’t. The forms ’s not and ’re not are more common after pronouns; isn’t and aren’t are more common after noun phrases:
Do + Not
The second most common auxiliary verb in the English language is 'do'. Let's see its different forms and how they can form a negation.
|Do||Do in Negative|
Have + Not
'Have' is another common verb. Like the other two, it can be used both as a main verb and an auxiliary verb. We can negate it by putting 'not' after it.
|Have||Have in Negative|
Modals + Not
All modal verbs can be negated by adding not (or n't after them). However, there is some exceptions to this rule. For example, you cannot use the contracted form of not with the modal verb 'may' and 'shall'. In the table below, you can see the list of those modal verbs that do not regularly take 'not'.
|Modal||Modal in negative|
Do you see in the first example that we have two auxiliary verbs: one is should and the other is have. Note that when this happens, always put 'not' after the first verb. See another example:
We use not or n't to form negative questions:
- 1. When there is a modal verb or be, we use not or n't to form negative questions;
- 2. When there is no modal verb or be, we use auxiliary verb do + n't.
In order to make a negative order or command, use this structure:
do + not/don't + the base form of the verb
Important Rule: Don't Negate a Verb Directly!
Remember that you cannot negate the main verb directly. You MUST use an auxiliary. Take a look at this example:
I have a sister.
In order to negate it, you cannot say:
haven't a sister.
not have a sister.
The only correct way is using an auxiliary verb:
Negative Non-finite Clauses
Non-finite clauses are clauses where the main verb is in the to-infinitive form, the -ing form, or the -ed form. The negative forms of non-finite clauses are made by putting not before them.

She didn't say anything,
With to-infinitive clauses, we can also use 'not' after to. However, it is not recommended. Many consider this 'split infinitive' to be unacceptable grammatically.
To negate a sentence we are forced to add not to its auxiliary verb. If a sentence has only an auxiliary verb what you do is to add not directly to the auxiliary. But if there is a main verb you are forced to use (do, does, did) as an auxiliary before the main verb to be allowed to add 'not__' to auxiliary ( do, does, did) and negate the whole sentence.
