Types of and Type of: What’s the Difference?

Should you say “this type of book” or “these types of books”? The phrases types of and type of look almost identical, but they do not always communicate the same meaning.

The main difference is number: type of usually refers to one category, while types of refers to two or more categories. However, choosing the correct phrase also depends on determiners, noun forms, context, and subject–verb agreement.

This article explains the difference with clear rules, comparison tables, questions, and everyday examples.

Quick Answer: Types of and Type of

The choice between these expressions mainly depends on whether you are discussing one category or several categories. The noun and determiner around the phrase must also match that meaning.

• Type of means one category, class, form, or variety.
• Types of means two or more categories, classes, forms, or varieties.

A useful rule is:

Use type of for one category and types of for more than one category.

The Difference Between Types of and Type of

Both phrases classify something by placing it into a group. The key difference is whether the speaker is referring to a single group or multiple groups.

“Type of” refers to one category

Use the singular word type when you are talking about one particular class, form, style, or category.

• This is a new type of phone.
• What type of food do you prefer?
• A whale is a type of mammal.
• That type of behaviour can cause problems.

In each sentence, the speaker is interested in one general category.

“Types of” refers to several categories

Use the plural word types when discussing more than one class, form, style, or category.

• The shop sells many types of phones.
• We tried three types of food.
• Scientists study different types of mammals.
• These types of behaviour are difficult to change.

Here, the speaker refers to multiple categories rather than one.

How to Use “Type of”

The phrase type of often follows a singular determiner such as a, one, this, or that. It can be followed by a countable or uncountable noun.

Common patterns

With singular countable nouns

A singular countable noun often follows a type of when one category is being identified.

• A laptop is a type of computer.
• A violin is a type of musical instrument.
• A bungalow is a type of house.
• An eagle is a type of bird.

The noun after of names the larger group.

With uncountable nouns

Uncountable nouns do not normally take a plural ending, even after type of.

• This type of music is relaxing.
• What type of information do you need?
• That type of equipment is expensive.
• We do not provide this type of advice.

Do not write informations, equipments, or advices in these examples because those nouns are normally uncountable.

When asking about one general category

Use what type of when you expect one general answer or want someone to identify a category.

• What type of car do you drive?
• What type of work does she do?
• What type of exercise is best for you?
• What type of books do you enjoy?

Notice that what type of books is correct. The word type is singular because the question asks for one general category, while books is plural because it refers to books as a group.

How to Use “Types of”

Use types of when you want to name, compare, count, or discuss several categories. It commonly follows words such as many, several, different, various, these, and those.

Common patterns

With plural countable nouns

A plural countable noun usually follows types of.

• different types of animals
• several types of computers
• many types of flowers
• two types of questions
• various types of buildings

This pattern clearly shows that several categories exist within a larger group.

With uncountable nouns

An uncountable noun remains uncountable after types of.

• different types of music
• several types of information
• various types of equipment
• two types of rice
• many types of furniture

The word types becomes plural, but the uncountable noun does not.

When listing several categories

Use types of when the sentence names or implies more than one category.

• The course covers three types of writing: descriptive, narrative, and persuasive.
• We grow several types of vegetables, including carrots, onions, and potatoes.
• The library contains different types of books, such as novels, biographies, and dictionaries.

What Type of vs. What Types of

Both question forms are correct, but they set different expectations. What type of usually asks for one general category, while what types of invites several categories.

Use “what type of” for one main answer

• What type of phone do you use?
• What type of pet does she have?
• What type of problem are you facing?
• What type of accommodation do they need?

The speaker expects one main category, although the answer may contain additional details.

Use “what types of” for a list

• What types of phones does the company sell?
• What types of pets are allowed?
• What types of problems did you find?
• What types of accommodation are available?

These questions encourage the listener to mention several categories.

Choosing the Correct Determiner

Words such as this, that, these, and those must agree with type or types. Singular determiners go with type, while plural determiners go with types.

Singular combinations

Use these expressions for one category:

• this type of
• that type of
• one type of
• each type of
• another type of

Examples:

• This type of lesson is easy to follow.
• That type of fabric dries quickly.
• Another type of treatment may be available.
• Each type of engine works differently.

Plural combinations

Use these expressions for more than one category:

• these types of
• those types of
• many types of
• several types of
• different types of
• various types of

Examples:

• These types of lessons help visual learners.
• Those types of fabrics require special care.
• Different types of engines use different fuels.
• Several types of treatment are being studied.

Singular and Plural Nouns After the Phrase

The noun following of does not depend only on type or types. It also depends on whether that noun is countable, uncountable, or being used as a category label.

The safest standard patterns

Countable noun examples

• one type of bird
• two types of birds
• this type of question
• these types of questions
• another type of vehicle
• several types of vehicles

Uncountable noun examples

• one type of water
• several types of water
• this type of software
• different types of software
• a type of bread
• many types of bread

Some nouns, including fish, fruit, cheese, and bread, may be countable or uncountable depending on meaning. When they refer to varieties, their usual uncountable form often remains natural.

• The shop sells five types of cheese.
• We tasted several types of bread.
• The region produces different types of fruit.

Subject–Verb Agreement

The verb usually agrees with type or types, because that word is the grammatical head of the subject. A singular type takes a singular verb, while plural types takes a plural verb.

Singular subject

• This type of problem is common.
• That type of machine requires regular maintenance.
• One type of exercise helps improve balance.
• Each type of flower has a different shape.

Plural subject

• These types of problems are common.
• Those types of machines require regular maintenance.
• Different types of exercise help improve balance.
• Several types of flowers have a strong scent.

Compare:

• This type of question is difficult.
• These types of questions are difficult.

The noun nearest the verb may be plural, but the verb still agrees with type or types.

Common Mistakes and Their Corrections

Most errors happen because the determiner, the word type, and the following noun do not agree. Checking whether you mean one category or several categories usually solves the problem.

1. Using “these type of”

Incorrect: These type of shoes are comfortable.
Correct: These types of shoes are comfortable.

These is plural, so it must modify the plural noun types.

2. Using “this types of”

Incorrect: This types of exercise improve strength.
Correct: This type of exercise improves strength.

This is singular and must be followed by type.

3. Using a singular countable noun after plural “types”

Less natural: We studied different types of animal.
Recommended: We studied different types of animals.

In modern everyday English, a plural countable noun is usually the clearest choice after types of.

4. Using a plural noun after “a type of”

Less natural: A tiger is a type of animals.
Correct: A tiger is a type of animal.

The phrase identifies one category within the larger group called animals.

5. Choosing the wrong verb

Incorrect: This type of mistake are common.
Correct: This type of mistake is common.

The singular subject type requires the singular verb is.

6. Using “different type” for multiple categories

Incorrect: The website offers different type of courses.
Correct: The website offers different types of courses.

The word different often signals that more than one category is being discussed.

Type of, Kind of, and Sort of

The nouns type, kind, and sort can all describe a category. In many sentences, they have similar meanings, although tone and usage may vary.

These sentences have nearly the same meaning:

• What type of film is it?
• What kind of film is it?
• What sort of film is it?

Their plural forms work in the same way:

• different types of films
• different kinds of films
• different sorts of films

However, kind of and sort of can also mean “slightly” or “somewhat” in informal speech.

• I am kind of tired.
• The instructions were sort of confusing.

In those sentences, they do not refer to categories.

A Fast Way to Choose the Correct Form

You can choose between type of and types of by asking one question: “Am I talking about one category or more than one?”

Use this three-step check:

1. Decide whether the meaning is singular or plural.
2. Match the determiner with type or types.
3. Check the noun and verb forms.

One category

• this type of book
• that type of music
• one type of machine
• what type of job

More than one category

• these types of books
• those types of music
• several types of machines
• what types of jobs

A useful memory pattern is:

This type is singular.
These types are plural.
