Choosing between “these or this” can feel confusing. Both words are common. Both point to people, things, ideas, or situations. So why do we say “this book” but “these books”?
The answer is simple: “this” is singular, while “these” is plural.
People often search for “these or this” because they are unsure which word should match a noun. The confusion can also happen when the noun is far from the word, when the sentence refers to an idea, or when English is not their first language.
This small grammar choice matters. A wrong demonstrative can make an email, essay, report, or social media post look less polished.
The good news is that the basic rule is easy to remember. Use this for one thing and these for more than one thing. Both words can refer to things that are close in space, time, or discussion.
This guide explains the difference, gives simple examples, covers common mistakes, and explains whether British and American English use different forms.
These or This Quick Answer
The quick rule is:
- This = one thing
- These = more than one thing
Examples:
- This book is interesting. → One book.
- These books are interesting. → More than one book.
- This idea could work. → One idea.
- These ideas could work. → Several ideas.
The same rule applies when the word stands alone:
- This is my phone.
- These are my phones.
“ This” is the singular form. “These” is the plural form. Both usually refer to something close to the speaker, either physically or in the current discussion.
Quick comparison
| Word | Number | Example |
| This | Singular | This car is fast. |
| These | Plural | These cars are fast. |
A useful memory trick is:
This = one. These = many.
Also remember the related pair:
- This = singular and near
- These = plural and near
- That = singular and farther away
- Those = plural and farther away
The Origin of These or This
The words this and these are very old. They developed from forms used in Old English.
Modern English has simplified the old demonstrative system, but it still keeps the basic distinction between singular and plural forms.
Today, the pattern is:
| Distance | Singular | Plural |
| Near | This | These |
| Far | That | Those |
The words do more than describe physical distance. They can also show distance in time or in a conversation.
For example:
- This meeting is important.
- These problems need attention.
- That event happened last year.
- Those mistakes caused delays.
English speakers can also use “this” or “these” to point back to something just mentioned. In writing, “this” can introduce or emphasize an idea, while “that” can create more distance from it.
Over time, English spelling changed, but this and these became the standard modern forms. The difference is grammatical rather than a regional spelling difference.
British English vs American English Spelling
Here is an important point: there is no British-versus-American spelling difference between “this” and “these.”
British English uses:
- This
- These
American English also uses:
- This
- These
The rule is the same in both varieties. “This” is singular, and “these” is plural. English grammar references from Cambridge and the British Council describe the same distinction.
This is different from words such as:
- colour / color
- centre / center
- organise / organize
Those can have regional spelling differences. This and these do not.
British English vs American English comparison
| Feature | British English | American English |
| Singular | This | This |
| Plural | These | These |
| “This book” | Correct | Correct |
| “These books” | Correct | Correct |
| Spelling difference | None | None |
| Main rule | Singular/plural | Singular/plural |
So, if you are writing for a US, UK, Canadian, Australian, Indian, Pakistani, or global audience, you do not need to change the spelling of this or these.
Which Spelling Should You Use?
You do not need to choose between British and American spelling for this and these. Both are standard everywhere.
Instead, choose the word based on the number of things you mean.
For a US audience
Use:
- This report is ready.
- These reports are ready.
For a UK or Commonwealth audience
Use:
- This report is ready.
- These reports are ready.
The grammar does not change.
For a global audience
Use the same rule:
One = this. More than one = these.
This is especially useful in:
- Business emails
- Websites
- SEO articles
- Academic papers
- School assignments
- Reports
- Social media
- Customer support
If you are unsure, look at the noun after the word. If the noun means one item, use this. If it means several items, use these.
Common Mistakes with These or This
1. Using “this” with a plural noun
Incorrect:
This books are useful.
Correct:
These books are useful.
“Books” is plural, so it needs these.
2. Using “these” with a singular noun
Incorrect:
These book is expensive.
Correct:
This book is expensive.
“Book” is singular, so use this.
3. Forgetting subject-verb agreement
Incorrect:
These books is helpful.
Correct:
These books are helpful.
With these, a plural noun normally takes a plural verb.
Compare:
- This book is helpful.
- These books are helpful.
4. Using “these” with an uncountable noun
Some nouns are normally uncountable.
Incorrect:
These information is useful.
Correct:
This information is useful.
Other examples include:
- This advice is helpful.
- This furniture is new.
- This equipment is expensive.
The noun, not the nearby words, determines the correct form.
5. Confusing “this kind” and “these kinds”
Compare:
This kind of problem is common.
and:
These kinds of problems are common.
The first sentence focuses on one kind. The second refers to multiple kinds.
6. Using “this” when referring to several items
Incorrect:
I bought three shirts. This are my new clothes.
Correct:
I bought three shirts. These are my new clothes.
Use these when the word replaces several things.
7. Choosing the word without checking the noun
When in doubt, ask:
Is it one or more than one?
- One → this
- More than one → these
That simple test solves most “these or this” questions.
These or This in Everyday Examples
The words this and these appear everywhere in English.
In emails
Singular:
Please review this document before the meeting.
Plural:
Please review these documents before the meeting.

In news writing
News writers often use demonstratives to connect ideas.
Singular:

The choice depends on whether the writer is pointing to one decision or several changes.
On social media
Social media often uses short sentences:

The rule stays the same, even in informal writing.
In formal writing
Academic and professional writing also follows the same rule:
This study examines consumer behavior.

Clear number agreement makes formal writing easier to read.

You might say:
What are these?
when pointing to several things.
English speakers also use these words for ideas:
This is a good idea.
These are good ideas.
