The difference between lets and let’s is small, but it changes the meaning of a sentence completely.
Many English learners, students, and even native speakers get confused because the only visible difference is an apostrophe.
However, these two words serve different grammatical purposes and cannot always replace each other.
The simple rule is this: let’s is a contraction of “let us,” while lets is the third-person singular form of the verb let, meaning allows or permits.
Both forms are correct, but each belongs in a different context. Knowing when to use each one will help you write more accurately in emails, essays, social media posts, and everyday conversations.
This guide explains the grammar rules, provides real-life examples, highlights common mistakes, and shows you how to choose the correct form with confiden

Both “let’s” and “lets” are correct, but they have different meanings.
- Let’s means “let us.” It’s a contraction and always includes an apostrophe.
- Lets is the third-person singular form of the verb let, meaning allows or permits.
| Word | Meaning | Grammar Role | Example |
|---|---|---|---|
| Let’s | Let us | Contraction | Let’s start the meeting. |

Let’s vs Lets at a Glance
| Feature | Let’s | Lets |
|---|---|---|
| Correct spelling | Yes | Yes |
| Has an apostrophe | Yes | No |
| Meaning | Let us | Allows or permits |
| Part of speech | Contraction | Verb |
| Used to make suggestions | Yes | No |
| Used with he, she, or it | No | Yes |
Although they look similar, they perform completely different jobs in a sentence.
What Does “Let’s” Mean?
“Let’s” = “Let Us”
Let’s is a contraction of let us. The apostrophe replaces the missing letter “u” in us.
For example:
- Let’s leave early.
- Let’s finish the report today.
- Let’s celebrate your success.
If you expand these sentences, they still make perfect sense:
- Let us leave early.
- Let us finish the report today.
- Let us celebrate your success.
Because the meaning stays the same, let’s is the correct choice.
Why Does “Let’s” Have an Apostrophe?
An apostrophe often shows that letters have been omitted from a contraction.
Just like:
- don’t = do not
- it’s = it is
- I’m = I am
Let’s follows the same rule:
- let’s = let us
This is one of the most common apostrophe rules in English grammar and is recognized by trusted references such as Merriam-Webster, Cambridge Dictionary, and Oxford English Dictionary.
Common Expressions with “Let’s”
You’ll often see let’s in everyday speech because it sounds friendly and inclusive.
Examples include:
- Let’s go for a walk.
- Let’s talk after lunch.
- Let’s see what happens.
- Let’s begin the presentation.
- Let’s take a short break.
- Let’s find another solution.
- Let’s work together on this project.
These expressions invite someone to do something together.
What Does “Lets” Mean?
Unlike let’s, lets is not a contraction. It is a verb.
It means allows, permits, or gives permission.
Examples:
- My teacher lets students ask questions anytime.
- The company lets employees work remotely twice a week.
- Our landlord lets us keep small pets.
- The app lets users edit photos with one click.
In every example, lets describes someone or something giving permission.
Subject–Verb Agreement
The word lets is only used with singular third-person subjects.
| Subject | Correct Verb |
|---|---|
| I | let |
| You | let |
| We | let |
| They | let |
| He | lets |
| She | lets |
| It | lets |
Correct Examples
- He lets his younger brother use his laptop.

- It lets users download files securely.
Incorrect Examples
- I lets my friends borrow my books. ❌

Instead, write:
- I let my friends borrow my books.
- They let us park here.
Understanding subject–verb agreement makes it much easier to choose the correct form and avoid one of the most common grammar mistakes involving lets and let’s.
Verb Forms of “Let”

| Base Form | let |
| Third-Person Singular | lets |
| Present Participle | letting |
| Past Tense | let |
