Too and Enough in English: Meaning, Grammar Rules and Examples

Too and enough are two very useful words in English. We use them to talk about quantity, degree and whether something is suitable or possible.

They may look simple, but many English learners make mistakes with word order.

Compare:

The bag is too heavy.
The bag is not light enough.
We have too much work.
We don’t have enough time.

In this lesson, you will learn how to use too and enough correctly, how they are different, and how to avoid common mistakes. These structures are especially useful for everyday English, B2 First and C1 Advanced writing and speaking.

The Main Difference Between Too and Enough

The easiest way to understand the difference is this:

Too means more than necessary or more than is good.

Enough means as much as necessary.

Look at these examples:

The coffee is too hot.	I cannot drink it because it is hotter than I want.
The coffee is hot enough.	It is the right temperature.
We have too many chairs.	We have more chairs than we need.
We have enough chairs.	We have the number of chairs we need.
He is too young to drive.	He cannot drive because he is not old enough.
He is old enough to drive.	He can drive because his age is suitable.

So, remember:

too = excessive / more than needed

enough = sufficient / as much as needed

How to Use Too in English

We use too when something is more than necessary, more than wanted, or more than is suitable.

1. Too + Adjective

Use too + adjective to say that something has more of a quality than is good or suitable.

Examples:

This soup is too salty.
The room is too small.

2. Too + Adverb

We can also use too before an adverb.

You’re speaking too quietly.
The teacher explained the rule too quickly.

This structure is useful when we want to describe how someone does something.

3. Too Much + Uncountable Nouns

Use too much with uncountable nouns.

Uncountable nouns include words such as:

money, time, water, sugar, traffic, homework, information, noise

You put too much sugar in my tea.
There is too much traffic in the city centre.

Common Mistake

Incorrect:

~~There are too much people in the room.~~

Correct:

There are too many people in the room. ✓

Why? Because people is countable, so we use too many.

4. Too Many + Countable Nouns

Use too many with countable plural nouns.

Countable plural nouns include:

people, books, cars, mistakes, problems, questions, chairs

There are too many people on the bus.
You’ve made too many mistakes in this paragraph.

Useful Patterns with Too

1. Too + Adjective + for Someone/Something

Use this structure when something is not suitable for a particular person or situation.

This coat is too big for me.
The film is too scary for children.

2. Too + Adjective + to + Infinitive

Use this structure when something is impossible or difficult because of an excessive quality.

Structure:

too + adjective + to + verb

I’m too tired to study.
The box is too heavy to lift.

Meaning:

I’m too tired to study
= I cannot study because I am very tired.
The box is too heavy to lift
= I cannot lift it because it is very heavy.

3. Too + Adjective + for Someone + to + Infinitive

This structure tells us who cannot do the action.

Structure:

too + adjective + for + person + to + verb

The bag was too heavy for her to carry.
The text was too difficult for me to understand.

This structure is very useful in exams because it allows you to create more complex sentences.

How to Use Enough in English

Enough means sufficient. It means that something is as much as we need.

However, the word order is different depending on whether we use enough with a noun, adjective or adverb.

This is the key rule:

enough + noun

adjective/adverb + enough

Let’s look at both.

1. Enough + Noun

When enough comes before a noun, it means that we have the amount we need.

We have enough chairs for everyone.
She doesn’t have enough experience for the job.

Enough with Countable and Uncountable Nouns

We can use enough with both countable and uncountable nouns.

Countable:

enough chairs
enough books
enough people
enough tickets

Uncountable:

enough money
enough time
enough water
enough information

Examples:

There aren’t enough chairs.
There isn’t enough water.
We don’t have enough books.
I don’t have enough information.

2. Adjective + Enough

When we use enough with an adjective, it comes after the adjective.

Structure:

adjective + enough

He is old enough to drive.
The room is big enough for all of us.

Common Mistake

Incorrect:

~~He is enough old to drive.~~

Correct:

He is old enough to drive. ✓

This is one of the most common mistakes learners make.

3. Adverb + Enough

We can also use enough after an adverb.

She speaks English well enough to study abroad.
He didn’t run fast enough to win the race.

4. Enough Without a Noun

Sometimes we use enough alone when the noun is already understood.

I can’t eat any more. I’ve had enough.
Three chairs aren’t enough.

Useful Patterns with Enough

1. Enough + Noun + for Someone/Something

We have enough food for everyone.
There isn’t enough space for all the guests.

2. Enough + Noun + to + Infinitive

Structure:

enough + noun + to + verb

We don’t have enough money to buy a car.
She has enough experience to manage the team.

3. Adjective + Enough + to + Infinitive

Structure:

adjective + enough + to + verb

He is old enough to vote.
She is confident enough to speak in public.

4. Adjective + Enough + for Someone + to + Infinitive

This structure tells us who can or cannot do the action.

The question was easy enough for everyone to answer.
The story was simple enough for children to understand.

Too and Enough: Direct Contrast

Sometimes we can express a similar idea using too or not enough.

Compare:

The coffee is too cold.	The coffee isn’t hot enough.
He is too young to drive.	He isn’t old enough to drive.
The room is too small.	The room isn’t big enough.
The bag is too heavy.	The bag isn’t light enough.
The test was too difficult.	The test wasn’t easy enough.

This is very useful for sentence transformations.

Too and Enough in B2 First and C1 Advanced

Too and enough are especially useful for Cambridge exams because they often appear in sentence transformations, essays, reports and speaking tasks.

Sentence Transformation Examples

Example 1

The room was too small for all the students.

ENOUGH

The room wasn’t big enough for all the students.

Example 2

A more natural version:

Example 3

TOO

We had too little time to visit the museum.

This is correct, but in everyday English, the first sentence sounds more natural.
