Let’s vs Lets: What’s the Difference? Meaning, Rules

Let’s and lets look almost identical, but they have different meanings and grammatical functions. Let’s is a contraction of “let us” and is commonly used to make suggestions, invitations, or proposals, such as “Let’s go home.” Lets is the third-person singular form of the verb “let,” meaning allows or permits, as in “She lets her children play outside.”

Understanding the difference between let’s vs lets is important because the apostrophe changes the meaning of the word. This small punctuation mark can turn a verb meaning “allows” into a phrase meaning “we should.”

The good news is that the rule is simple once you know what each form means. If you are a student, ESL learner, writer, or everyday English speaker, learning when to use let’s and lets will help you write more accurately and confidently.

Quick Answer

Let’s means “let us” and is used mainly for suggestions or invitations: “Let’s study together.” Lets is a verb meaning “allows” or “permits”: “My teacher lets us ask questions.” Use the apostrophe in let’s when you could replace it with let us.

Why People Confuse It

People often confuse let’s and lets because they sound the same when spoken. The only visible difference is the apostrophe, but that apostrophe represents missing letters in the contraction let us → let’s.

The words also appear in similar sentence positions. For example:

• Let’s eat dinner.
• She lets us eat dinner early.

The first is a suggestion. The second says that someone allows something to happen.

First Word: Let’s

Let’s is a contraction of “let us.” It is generally used when the speaker is suggesting that we do something together.

Common uses of “let’s”

• Making a suggestion
• Giving an invitation
• Proposing an action
• Encouraging someone
• Starting a shared activity

Examples:

• Let’s go for a walk.
• Let’s finish this project today.
• Let’s try again.
• Let’s watch a movie tonight.

A useful test is to replace let’s with let us.

If the expanded version makes sense, let’s is probably correct.

Second Word: Lets

Lets is the third-person singular form of the verb “let.” It means allows, permits, or gives someone permission to do something.

It is used with subjects such as he, she, it, or a singular noun.

Examples:

• She lets me use her laptop.
• My father lets me drive his car.
• The teacher lets students ask questions.
• This software lets you edit photos.

Notice that lets does not need an apostrophe because it is not a contraction.

Use “let’s” for suggestions

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

• Let’s have lunch.
• Let’s meet tomorrow.
• Let’s start the lesson.

Use “lets” for permission

Use lets when someone or something allows another person to do something.

• She lets me borrow her books.
• The app lets users save their work.

Use “let us” when appropriate

In some formal or traditional contexts, let us may be preferable to let’s, especially when the full phrase sounds more formal.

For example:

In ordinary conversation, however, let’s is much more common.

Common Mistakes

Mistake 1: Using “lets” for a suggestion

❌ Lets go shopping.

✅ Let’s go shopping.

You are suggesting that you and someone else go shopping, so let’s is correct.

Mistake 2: Using “let’s” for “allows”

❌ My brother let’s me use his computer.

✅ My brother lets me use his computer.

Here, lets means allows, so no apostrophe is needed.

Mistake 3: Thinking every word ending in “s” needs an apostrophe

An apostrophe is not used simply because a word ends in s. In lets, the s is part of the verb form.

Mistake 4: Forgetting that “let’s” means “let us”

When unsure, expand the word:

Let’s → let us

If that meaning works, use let’s.

Memory Trick

Remember this:

Let’s = Let Us = Suggestion

Lets = Allows = Permission
