These or This: The Simple Guide to Using Them Correctly

Have you ever written a sentence and stopped to ask, “Should I use these or this?” The two words look very similar, but they do not have the same job.

Choosing the right one depends mainly on whether you are talking about one thing or more than one thing. This small grammar rule can cause confusion in emails, essays, social media posts, schoolwork, and professional writing.

People often search for these or this because they want a quick way to understand the difference. The good news is that the rule is simple.

This is normally used with a singular noun, while these is used with a plural noun. Both words usually point to something that is near in place, time, or context.

In this guide, you will learn the difference between these and this, their history, common mistakes, everyday examples, and useful grammar rules. By the end, you will know exactly when to use each word.

These or This Quick Answer

The quick answer is:

• This = singular
• These = plural

Both normally point to something that is near the speaker or close in time or context.

Examples with “this”

• This book is interesting
• This car is new
• This idea could work
• This is my phone

Here, each noun is singular.

Examples with “these”

• These books are interesting
• These cars are new
• These ideas could work
• These are my phones

Here, the nouns are plural.

A useful rule is:

This + singular noun
These + plural noun

Compare:

Singular	Plural
This book is new.	These books are new.
This apple is fresh.	These apples are fresh.
This student is ready.	These students are ready.
This idea is useful.	These ideas are useful.

The verb also changes. Use is with “this” and are with “these.”

The Origin of These or This

This and these are old English demonstrative words. 

They belong to a group of words that point to people, things, places, or ideas. Modern English has four main demonstratives: this, that, these, and those.

Over time, English developed a clear pattern based on two ideas: number and distance.

• This refers to one nearby thing
• These refers to several nearby things
• That refers to one more distant thing
• Those refers to several more distant things

The difference is therefore not a spelling variation. This and these are different grammatical forms.

For example:

• This chair is comfortable
• These chairs are comfortable

The first sentence refers to one chair. The second refers to more than one chair.

Distance can also be about time or ideas, not only physical space. 

For example, this week can mean the current week, while these days can refer to the present period. Demonstratives can also refer to things close or distant in a conversation.

British English vs American English Spelling

There is no spelling difference between British English and American English for this and these. Both varieties use the same forms and follow the same basic singular and plural rule.

British English

• This book is useful
• These books are useful
• This is my pen
• These are my pens

American English

• This book is useful
• These books are useful
• This is my pen
• These are my pens

The important point is that this is singular and these is plural in both major varieties of English.

Comparison Table

Feature	This	These
Number	Singular	Plural
Basic meaning	One	More than one
Distance	Usually near	Usually near
With a noun	This book	These books
As a pronoun	This is good.	These are good.
Verb commonly used	Is	Are
British spelling	This	These
American spelling	This	These

Unlike words such as colour/color, there is no British-versus-American spelling issue here. The choice depends on grammar, not geography.

Which Spelling Should You Use?

You do not need to choose between a British spelling and an American spelling when using this or these. The correct choice depends on whether the noun is singular or plural.

For US English

Use:

• this for one thing
• these for more than one thing

Example:

This computer is fast.
These computers are fast.

For UK and Commonwealth English

The same rule applies:

This house is large.
These houses are large.

For global English

If you write for an international audience, use the same grammar rule. This and these are standard in both British and American English.

The easiest question to ask is:

Am I talking about one thing or more than one?

If it is one, choose this.
If it is more than one, choose these.

Common Mistakes with These or This

Mistake 1: Using “this” with a plural noun

Incorrect:

This books are expensive.

Correct:

These books are expensive.

“Books” is plural, so use these.

Mistake 2: Using “these” with a singular noun

Incorrect:

These book is expensive.

Correct:

This book is expensive.

“Book” is singular, so use this.

Mistake 3: Using the wrong verb

Incorrect:

These is my shoes.

Correct:

These are my shoes.

These is plural, so it normally takes are.

Mistake 4: Saying “this are”

Incorrect:

This are my documents.

Correct:

These are my documents.

Mistake 5: Confusing “these” with “those”

These usually points to things that are near.

These shoes are mine.

Those usually points to things that are farther away.

Those shoes are mine.

Distance can also be about time or context, so the difference is not always physical.

Mistake 6: Forgetting that “this” can stand alone

“This” does not always need a noun after it.

This is delicious.

Here, this is a demonstrative pronoun.

Likewise:

These are delicious.

Here, these replaces a plural noun.

These or This in Everyday Examples

Knowing the rule is useful, but seeing these words in real situations makes the difference easier to remember.

In emails

Singular:

This document contains the information you requested.

Plural:

These documents contain the information you requested.

In news writing

Singular:

This decision could affect local businesses.

Plural:

These changes could affect local businesses.

News writing often uses demonstratives to connect a sentence with information already discussed.

On social media

Singular:

This photo makes me smile.

Plural:

These photos are from my trip.

In formal writing

Singular:

This method provides a simple solution.

Plural:

These methods provide simple solutions.

Notice the verb change:

• This method provides
• These methods provide

In conversation

You might say:

What is this?

Or:

What are these?

The singular and plural forms naturally change the verb as well. Oxford Learner’s Dictionaries gives the same basic pattern: “This is” for singular and “These are” for plural.

These or This Google Trends & Usage Data

Searches for “these or this” usually come from people trying to solve a grammar choice, rather than from a spelling difference. 

Google Trends can show interest in grammar questions, but search interest changes by country, language-learning needs, season, and search wording.

The important usage pattern is clear across standard English grammar references: this is the singular form, while these is the plural form.

In countries where English is widely taught as a second language, learners may search for questions such as:

• these or this
• this or these
• this is or these are
• this book or these books

The words themselves are extremely common because they are basic English demonstratives used in speech and writing.

Google Trends data should therefore be treated as a measure of search interest, not as a measure of grammatical correctness. 

A higher search volume for one phrase does not mean that one grammatical form is more correct.

For usage, the reliable rule remains simple:

This = one
These = more than one

These students	This student

Both are commonly used to point to things that are near in space, time, or context.

There is no British-versus-American spelling difference between these words. 

The same grammar rule works in US English, UK English, Commonwealth English, and international English. 

The most useful pattern to remember is “this + singular” and “these + plural.”

For example, say “This book is helpful” when talking about one book. Say “These books are helpful” when talking about several books. 

Also remember the matching verbs: this is and these are.

If you are unsure, look at the noun that follows the demonstrative. One means this; more than one means these. 

Once you learn this simple pattern, you can use both words confidently in emails, conversations, social media posts, news writing, and formal documents.
