To Not or Not To Which Is Correct Complete Grammar Guide 2026

English learners often stop when they see two forms such as to not and not to. Both can look correct, and both can appear in real English. This is why to not or not to can be confusing, especially for students who learned that “not” always comes before the infinitive phrase.

The good news is that the basic idea is simple. Both forms can be grammatical, but they are not always used in exactly the same way. In many sentences, not to is the more traditional and common choice. In other sentences, to not can sound natural and can place special focus on the negative action.

For example:

• I decided not to go.
• I decided to not go.

The first sentence is usually the safer choice in formal writing. The second can also be correct, especially when the writer wants to make the negative action stand out.

Understanding to not or not to is useful because infinitives are very common in everyday English. You will see these forms after verbs such as want, decide, try, hope, plan, and need.

By the end, you will know when to use each form, how their sentence structures work, what mistakes to avoid, and which form is usually the best choice for formal English.

What Does “To Not” Mean?

To not is an infinitive with the negative word not placed between to and the base verb.

The basic structure is:

to + not + base verb

For example:

• to not worry
• to not complain
• to not forget
• to not answer
• to not disturb
• to not interrupt

The form to not means that the action described by the verb should not happen. It is often used when the speaker or writer wants to put clear attention on the negative action To Not or Not To.

Consider this sentence:

She chose to not attend the meeting.

The meaning is that she chose not to attend. The focus can feel slightly stronger on the decision to not attend.

Here are several natural examples:

1. I decided to not tell him the secret.
2. We agreed to not discuss the problem today.
3. He tried to not laugh during the speech.
4. She promised to not make the same mistake.
5. They chose to not accept the offer.
6. I am trying to not worry about small things.
7. He asked me to not touch the machine.
8. She wanted to not upset her parents.

The construction is not automatically wrong. Some learners are taught that splitting to from the verb is always incorrect. That old rule is too simple.To Not or Not To.

English does allow words to come between to and the base verb in many situations. The important question is whether the sentence sounds natural and whether the placement gives the intended meaning.

For learners comparing to not or not to, it is helpful to remember that to not is especially common when the writer wants the negative idea to be clear or strongly connected to the verb that follows.

However, this does not mean you should always choose it. In many situations, not to remains the more natural and traditional form.To Not or Not To.

What Does “Not To” Mean?

Difference Between “To Not” and “Not To”

The main difference between to not or not to is usually not a completely different meaning. In many sentences, the two forms communicate essentially the same idea.To Not or Not To.

Compare:

I decided not to call her.

and:

I decided to not call her.

Both mean that I made a decision not to call her.

However, the first sentence is generally more traditional and more common. The second can give a little more attention to the negative action.

Feature	To not	Not to
Basic structure	to + not + verb	not + to + verb
Meaning	Negative infinitive	Negative infinitive
Commonness	Common in some contexts	Very common
Formal writing	Acceptable	Usually preferred
Spoken English	Natural in many situations	Very natural
Main use	Can emphasize the negative action	Standard negative infinitive
Example	I chose to not go.	I chose not to go.

When comparing to not or not to, think about the position of not.

With not to, the negative word comes before the whole infinitive:

I decided not to leave.

With to not, not comes directly after to:

I decided to not leave.

The meaning is usually very close.

The choice can depend on style, emphasis, rhythm, and the surrounding sentence. Native speakers do not use one form in every situation.To Not or Not To.

For example:

She tried not to laugh.

This is very natural.

But:

She tried to not laugh.

This can also work, especially when the speaker wants to emphasize the action of not laughing.To Not or Not To.

So, the question is not simply “Which one is grammatically correct?” A better question is:

Which form sounds most natural and clearly expresses the intended focus?

Grammar Rules You Must Remember

1. Use “not to” as the safe standard choice

When you are writing a formal sentence and you are unsure, not to is usually the safest option.

For example:

We decided not to cancel the event.

This sounds natural in academic, professional, and everyday English.

Another example:

He promised not to make the same mistake again.

There is nothing unusual about this structure.

For students learning to not or not to, this simple rule can prevent many unnecessary mistakes.

2. “To not” is not automatically incorrect

Do not assume that every sentence containing to not is wrong.

For example:

I chose to not answer the phone.

This sentence can be perfectly grammatical.To Not or Not To.

The writer may want the phrase to not answer to feel like one clear choice.

The idea is similar to:

I chose to not participate.

Here, the negative action itself is being presented as the choice.

3. Both forms use the base verb

After the infinitive marker to, the verb remains in its base form.

Correct:

I decided not to go.To Not or Not To.

Correct:

I decided to not go.

Incorrect:

I decided not to went.

Incorrect:

I decided to not going.

The negative word does not change the basic infinitive structure.To Not or Not To.

4. Do not confuse “not to” with “don’t”

The forms are different.

I decided not to go.

Here, not to go is an infinitive phrase.

But:

I don’t go there.

Here, don’t is part of a present-tense verb phrase.To Not or Not To.

Do not replace one structure with the other just because both can express a negative idea.

Common Mistakes Students Make

Mistake 1: Thinking “to not” is always wrong

This is probably the biggest problem with to not or not to.

Some learners have heard that you must never put a word between to and the verb. That idea comes from an old grammar rule about the so-called “split infinitive.”

Modern English does not treat every split infinitive as an error.To Not or Not To.

For example:

She decided to not participate.

This can be acceptable.

However, if you are writing a formal school assignment, not to participate may sound more traditional:

She decided not to participate.

Mistake 2: Thinking the two forms always have different meanings

Usually, they do not have a major difference in basic meaning.To Not or Not To.

Compare:

He tried not to cry.

He tried to not cry.

Both tell us that he made an effort to avoid crying.To Not or Not To.

The difference is mostly about placement and emphasis, not a completely different action.

Mistake 3: Using “not” in the wrong place

Learners sometimes create sentences such as:

I decided to not went.

The problem is not the position of not. The problem is went.To Not or Not To.

After to, use the base form:

I decided to not go.

Or:

I decided not to go.

Mistake 4: Using “don’t to”

Another common mistake is:

I decided don’t to go.

That is incorrect.

Use:

I decided not to go.

Or, in a suitable context:

I decided to not go.

The word don’t cannot replace not in an infinitive structure.

Easy correction tip

Whenever you see to followed by a verb, ask yourself:

Am I making a negative infinitive?

If yes, you normally have two possible patterns:

not + to + verb

or, in suitable contexts:

to + not + verb

When you are unsure, choose not to.

Easy Trick to Remember the Difference

Here is a simple classroom trick for remembering to not or not to.

Think of not to as your default door.

If you need a negative infinitive and you do not have a special reason to choose another structure, walk through the not to door.

For example:

I decided not to leave.

She promised not to complain.

We agreed not to argue.

These forms are easy, natural, and widely used.

Now think of to not as a way of putting extra attention on the negative action.

Imagine someone asks:

Are you going to join the discussion?

You might say:

No. I decided to not participate.

The focus can fall more strongly on the choice to not participate.

This is not a strict rule. Native speakers may use either structure depending on the sentence.

The best practical rule for learners is:

Use “not to” when you want the normal, traditional form. Consider “to not” when the negative action needs special focus or sounds better in the sentence.

That simple idea will help you understand most examples of to not or not to.

Daily Life Examples

Real Conversations

You can hear both patterns in real-life English.

1. Making a decision

“Are you going to the party?”

“No, I decided not to go.”

This is probably the most natural everyday choice.

2. Refusing something

“Why didn’t you answer his message?”

“I chose to not reply because I was upset.”

Here, to not reply highlights the choice not to reply.

3. Avoiding a problem

“What did your teacher tell you?”

“She told us not to use our phones.”

This is a very common instruction.

4. Controlling laughter

“Why were you looking down?”

“I was trying not to laugh.”

This sounds very natural in conversation.

5. Making a promise

“Are you going to tell anyone?”

“No. I promise not to tell anyone.”

The form not to tell is the natural standard choice.

6. Making a personal choice

“Why didn’t you join them?”

“I decided to not get involved.”

This form can emphasize the decision to avoid involvement.

7. Giving advice

“What should I do?”

“Try not to worry too much.”

This is a very common expression.

8. Avoiding an argument

“Did you talk to Sam?”

“No. I tried not to start an argument.”

The speaker explains an effort to avoid something.

9. Choosing silence

“Why didn’t you say anything?”

“I decided to not say anything until I knew the facts.”

Here, the negative action is presented as a deliberate choice.

10. Remembering a rule

“What did the sign say?”

“It told visitors not to touch the paintings.”

This is a standard and natural use of the negative infinitive.

These examples show why to not or not to is not simply a matter of right versus wrong. Context and emphasis can influence which form sounds better.
