Lets or Let’s: Which Spelling Is Correct? 

Have you ever stopped while writing and wondered whether it should be “lets” or “let’s”? You are not alone. These two forms look almost identical and sound the same in many sentences, but they have different meanings and grammar roles.

The small apostrophe in “let’s” can change the meaning of the whole sentence. For example, “Let’s go home” means “Let us go home.” But “She lets me go home” means that she allows me to go home.

This simple difference matters in emails, school assignments, websites, social media posts, business writing, and everyday English. Many people search for “lets or let’s” because they are unsure when the apostrophe is needed.

The good news is that the rule is easy once you know what each form means. In this guide, you will learn the difference between lets and let’s, where the words come from, how they are used in British and American English, common mistakes, and an easy trick for choosing the correct form.

Lets or Let’s – Quick Answer

The quick answer is:

• Let’s = let us. It is a contraction used mainly to make a suggestion or encourage an action.
• Lets = the third person singular form of the verb let. It usually means allows or permits.

Examples of “let’s”

• Let’s go to the park.
• Let’s start the meeting.
• Let’s study together.
• Let’s try again.
• Let’s not waste time.

In these examples, let’s means let us.

For example:

Let’s study together.

can be expanded to:

Let us study together.

Cambridge defines let’s as a form used to make a suggestion or request that includes the speaker and the other person or people.

Examples of “lets”

• She lets me use her laptop.
• My teacher lets us ask questions.
• This app lets users save files.
• He lets his children play outside.

Here, lets means allows or permits.

For example:

This app lets you edit photos.

means:

This app allows you to edit photos.

Oxford lists lets as the third person singular present form of let.

The easiest test

Try replacing let’s with let us.

If the sentence still makes sense, use let’s.

Let’s go home.
→ Let us go home. ✅

But:

This phone lets you take better photos.
→ This phone let us you take better photos. ❌

So the correct form is lets.

The Origin of Lets or Let’s

Both lets and let’s come from the verb let, but they developed different grammatical functions.

The verb let is very old. Oxford traces the verb to Old English lǣtan, with meanings connected to leaving or allowing. It is of Germanic origin and is related to words in languages such as Dutch and German.

An Old English reference also records lǣtan with meanings such as “let” and “allow.”

Over time, let became an important English verb with several related uses, including:

• allow
• permit
• release
• allow someone to do something
• rent out, especially in British English

The form lets developed as the third person singular present form.

For example:

She lets me use her car.

The subject is she, so the verb becomes lets.

Where does the apostrophe in “let’s” come from?

Let’s is a contraction of let us.

The apostrophe shows that letters have been left out. In this case:

let us → let’s

The contraction became established in English centuries ago. Historical sources trace its use back to Early Modern English, with evidence of the contracted form appearing by the Elizabethan period.

This is why the apostrophe is important. It is not simply decorative punctuation.

Compare:

Let’s eat.
= Let us eat.

She lets us eat.
= She allows us to eat.

The words look similar, but their grammar is different.

British English vs American English Spelling

There is an important point to understand: British and American English do not normally spell these two forms differently.

Both varieties use:

• let’s for the contraction
• lets for the third person singular verb

So you should not think of lets as the British spelling and let’s as the American spelling. That would be incorrect.

Comparison table

Feature	Lets	Let’s
Apostrophe	No	Yes
Full form	Let	Let us
Grammar	Verb	Contraction
Main meaning	Allows or permits	Suggests an action
Common subject	He, she, it	We/us idea
Example	She lets me leave.	Let’s leave.
American English	Used	Used
British English	Used	Used

British English examples

She lets her children play outside.

Let’s go home before it gets dark.

American English examples

The software lets you change the settings.

Let’s check the results again.

The spelling remains the same in both varieties.

There can be differences in how let is used in other contexts. For example, British English commonly uses let in the sense of renting property, as in “a flat to let.” Oxford identifies this as a British English usage.

But this does not change the basic rule for lets vs. let’s.

Which Spelling Should You Use?

The correct spelling depends on what you want to say, not on whether your audience is American or British.

Use “let’s” for suggestions

Use let’s when you are suggesting that you and another person or group do something.

Examples:

• Let’s begin.
• Let’s go outside.
• Let’s take a break.
• Let’s solve this problem.
• Let’s talk about it.
• Let’s try another method.

You can usually test the sentence by using let us.

Let’s start.

→ Let us start.

Use “lets” when you mean “allows”

Use lets when the subject is singular and you mean allows or permits.

Examples:

• My mother lets me drive her car.
• The teacher lets students use calculators.
• This website lets users create an account.
• The hotel lets guests check in early.
• The program lets you save your work.

A useful pattern is:

He/she/it + lets + person + base verb

For example:

She lets me work from home.

Not:

She let’s me work from home. ❌

What about global English?

For international readers, the same basic rule works.

Whether you are writing for readers in:

• the United States
• the United Kingdom
• Canada
• Australia
• New Zealand
• India
• Pakistan
• or another English speaking market

the standard distinction remains the same.

If you mean “let us,” write let’s.

If you mean “allows,” write lets.

Common Mistakes with Lets or Let’s

The most common mistake is adding an apostrophe where it does not belong.

Mistake 1: “Let’s” when you mean “allows”

❌ This tool let’s you edit images.

✅ This tool lets you edit images.

Why?

The tool is not suggesting something. It allows you to edit images.

Mistake 2: “Lets” when you mean “let us”

❌ Lets go to the beach.

✅ Let’s go to the beach.

The sentence is a suggestion.

Let’s = let us.

Mistake 3: “She let’s me”

❌ She let’s me use her phone.

✅ She lets me use her phone.

The subject is she, so lets is the correct verb form.

Mistake 4: “Lets us” vs. “Let’s us”

These forms can also confuse writers.

❌ Let’s us know when you arrive.

Usually, if you mean allows us, use:

✅ The teacher lets us leave early.

If you are asking someone to inform you, use:

✅ Let us know when you arrive.

Notice that let us know here is not the same as the suggestion let’s know.

Mistake 5: Using “let’s” automatically before “you”

Consider:

This feature lets you download the file.

Correct.

The feature allows you to download the file.

But:

Let’s download the file.

also works, but it has a different meaning.

Here, the speaker is suggesting that we download the file.

Lets or Let’s in Everyday Examples

Understanding real life examples makes the difference much easier.

In emails

Let’s discuss the project tomorrow.

This is a suggestion.

The new system lets employees submit forms online.

Here, lets means allows.

In business writing

Let’s review the proposal before the meeting.

This encourages a group action.

The software lets companies manage customer information.

This means the software allows companies to manage information.

In school writing

Let’s examine the main argument.

This is a suggestion.

The new method lets students complete the task faster.

This means the method allows students to complete the task.

In news writing

You may see phrases such as:

Let’s look at the latest results.

This is a way of inviting readers or viewers to consider something.

You may also see:

The new policy lets residents apply online.

Here, lets means allows.

On social media

Social media often uses let’s because it is conversational.

Examples:

• Let’s talk about it.
• Let’s try this trend.
• Let’s celebrate!
• Let’s make it happen.
• Let’s see what happens next.

In formal writing

Both forms can appear in formal writing, but let’s is still a contraction.

For a more formal tone, writers sometimes use let us when appropriate.

For example:

Let us examine the evidence.

This can sound more formal than:

Let’s examine the evidence.

However, you should not replace every use of let’s with let us. Sometimes let us has a different meaning.

Compare:

Let’s go.

This normally suggests that the speaker and listener should go.

But:

Please let us go.

means please allow us to go.

That is an important difference.

Lets or Let’s – Google Trends & Usage Data

People search for “lets or let’s” because the two forms are easy to confuse. The problem is especially common in online writing, where apostrophes are sometimes forgotten.

Search interest for grammar questions can change by country, education level, language learning activity, and online writing habits. Google Trends can be used to compare relative search interest for phrases such as:

• lets or let’s
• lets vs let’s
• let’s or lets
• lets meaning
• let’s meaning

However, Google Trends reports relative search interest, not the exact number of searches. A Trends score of 100 represents the highest point of interest within the selected comparison and time period; it does not mean 100 searches.

For this reason, a fixed statement such as “Country X searches this keyword exactly 50,000 times per month” should not be made from Google Trends alone.

The available dictionary evidence confirms that let’s is a standard contraction of let us, while lets is the third person singular form of let.

Why this keyword has lasting search value

The confusion is unlikely to disappear because:

• Apostrophes are easy to miss.
• Both forms are pronounced the same.
• English learners often confuse contractions with verb forms.
• People write quickly in emails and social media.
• Grammar questions are common in school and professional writing.
• The difference changes the meaning of a sentence.

This makes “lets or let’s” a useful grammar topic for learners who want a quick answer and clear examples.
