Have you ever typed “Lets go!” and wondered whether you need an apostrophe? The difference between lets and let’s is only one tiny mark, but that apostrophe completely changes the meaning and grammatical function of the word.
So, lets or let’s which one is correct? The answer is: both are correct, but they are used in different situations. Let’s is a contraction of “let us,” usually used to make a suggestion, while lets is the third-person singular form of the verb let, meaning “allows.”
This guide explains the difference between lets and let’s, shows you when to use each one, and gives you a simple trick to avoid the mistake.

Lets or Let’s: What Is the Difference?
The easiest way to understand the difference is to look at their meanings.
Let’s means “let us” and is generally used to suggest that the speaker and another person or group do something together.
Let’s go for a walk.
Here, let’s means something like “Let us go for a walk.”
On the other hand, lets is a form of the verb let and means allows or permits.
My mother lets me stay up late on weekends.
Here, lets means allows.
Cambridge Dictionary confirms that let’s is used to make a suggestion or request that includes the speaker and other people, while let can mean to allow someone to do something.
Quick Difference
| Word | Meaning | Example |
|---|---|---|
| let’s | let us; makes a suggestion | Let’s start now. |
| lets | allows or permits | She lets me use her laptop. |
Therefore, the apostrophe is not optional. It signals that let’s is a contraction.
When to Use “Let’s”
Use let’s when you are suggesting an action that includes yourself and another person or group.
The word is short for “let us.”
Let’s Means “Let Us”
Try expanding let’s to let us.
Let’s go home.
Let us go home.
The meaning still works, so let’s is correct.
Here are more examples:
- Let’s have some coffee.
- Let’s finish this project today.
- Let’s watch a movie tonight.
- Let’s take a short break.
- Let’s discuss the problem.
- Let’s try again tomorrow.
Cambridge describes let’s as the common shortened form used for suggestions that include the speaker and other people.
Let’s + Base Verb
After let’s, use the base form of the verb.
Correct:
Let’s go outside.
Let’s eat lunch.
Let’s start the meeting.
Incorrect:
Let’s goes outside.
Let’s eats lunch.
Let’s starting the meeting.
The basic pattern is:
Let’s + base verb
Negative Form: “Let’s Not”
When suggesting that people should avoid an action, use let’s not.
Examples:
Let’s not argue about this.
Let’s not waste any more time.
Let’s not forget the deadline.
Cambridge notes that let’s not is the more common negative form compared with the less common “don’t let’s.”

When to Use “Lets”
Use lets without an apostrophe when it is the third-person singular form of let.
In this situation, lets usually means allows or permits.
Lets Means “Allows”
Consider this sentence:
My teacher lets us ask questions.
This means:
My teacher allows us to ask questions.
More examples:
- My dad lets me drive his car.
- Sarah lets her children play outside.
- The manager lets employees work from home.
- This app lets users edit their photos.
- The teacher lets students use dictionaries.
- The software lets you save your work.
Notice that the subject is usually he, she, it, or a singular noun.
Lets in a Simple Grammar Pattern
A useful structure is:
Subject + lets + person/object + base verb
For example:
She lets me use her computer.
The teacher lets students ask questions.
This feature lets users save files.
Do not add to after the object in this structure.
Correct:
She lets me go.
Incorrect:
She lets me to go.
Cambridge explains that let takes an object followed by an infinitive without to.
“Lets” Can Also Relate to Renting
In British English, let can also mean to rent a property to someone.
For example:
They let their apartment to a young couple.
This produces the third-person form:
The company lets several properties each year.
This meaning is less common for many learners, but it is another legitimate use of let/lets.

Lets vs. Let’s: The Easy Trick That Works
If you are unsure whether to write lets or let’s, use a simple replacement test.
The “Let Us” Test
Replace the word with “let us.”
If the sentence still makes sense, use let’s.
Let’s go home.
↓
Let us go home.
Correct: let’s
Now try:
She lets me go home early.
↓
She let us me go home early.
That does not work.
Therefore, the correct word is lets.
The “Allows” Test
You can also replace lets with allows.
My teacher lets me leave early.
↓
My teacher allows me to leave early.
The meaning works, so lets is correct.

| If you can replace it with… | Use |
|---|---|
| let us | let’s |
| allows | lets |
This is one of the simplest ways to remember the difference.
A Simple Memory Rule
Remember:
Let’s = suggestion
Lets = allows
For example:
Let’s study together. → Suggestion
My teacher lets me study here. → Permission
That single distinction will help you get most examples right.

A Real-Life Example: “Lets” vs. “Let’s” in Everyday Writing
Imagine a student named Emma is working on a group project with two classmates. She sends a message to the group chat saying:
“Lets meet at 4 p.m. to finish our presentation.”
The sentence is understandable, but the apostrophe is missing. Emma is making a suggestion that includes herself and her classmates. She could expand the sentence to:
“Let us meet at 4 p.m. to finish our presentation.”
Therefore, the correct version is:
“Let’s meet at 4 p.m. to finish our presentation.”
Later, Emma tells her friend about her teacher:
“Our teacher lets us submit the presentation tomorrow.”
This time, there is no apostrophe. Why? Because lets means allows.
The teacher allows the students to submit the presentation tomorrow.
This example shows why the apostrophe matters. Compare the two sentences:
Let’s finish the presentation.
This is a suggestion: I suggest that we finish it.
Our teacher lets us finish the presentation tomorrow.
This describes permission: Our teacher allows us to do it tomorrow.
The pronunciation can make these words especially confusing because lets and let’s are normally pronounced the same. However, their grammatical roles are different. LanguageTool’s 2025 article, revised in 2026, likewise identifies let’s as the contraction of let us and lets as the third-person singular form of let.
This distinction is particularly useful in emails, assignments, work messages, captions, and other forms of writing where punctuation affects clarity.
Common Mistakes With Lets and Let’s
Even though the rule is simple, several mistakes appear frequently.
Mistake 1: Writing “Lets go”
Incorrect:
Lets go to the park.
Correct:
Let’s go to the park.
Why? You are suggesting that you and someone else go to the park.
You can test it:
Let us go to the park.
So the apostrophe belongs in let’s.
Mistake 2: Adding an Apostrophe to “Lets”
Incorrect:
My father let’s me use his car.
Correct:
My father lets me use his car.
Here, lets means allows.
The apostrophe changes the grammatical function.
Mistake 3: Using the Wrong Verb Form
Incorrect:
Let’s goes shopping.
Correct:
Let’s go shopping.
Incorrect:
She lets me goes home early.
Correct:
She lets me go home early.
Both structures use the base verb after let/lets.
Mistake 4: Adding “To” After Lets
Incorrect:
She lets me to use her phone.
Correct:
She lets me use her phone.
The verb after let + object is normally used without to.

Lets vs. Let’s: 2025–2026 Usage and Grammar Evidence
There is an important distinction between usage data and grammar rules. Current public sources do not provide a reliable 2025–2026 percentage showing how often English writers confuse lets and let’s. Therefore, it would be misleading to invent a statistic or claim that a specific percentage of people make this error.
However, current 2025–2026 English-language resources continue to document the distinction consistently. LanguageTool published a dedicated “Lets vs. Let’s” explanation in June 2025 and revised it in February 2026, while Cambridge Dictionary’s current grammar guidance continues to define let’s as the short form used for suggestions and let as a verb used for permission.
A useful current-data point is therefore the publication/revision evidence itself:
- 2025: LanguageTool published its dedicated explanation of lets vs. let’s.
- 2026: LanguageTool revised that explanation, showing the distinction remains relevant in contemporary English-learning resources.
- 2026: Cambridge Dictionary’s current grammar guidance continues to distinguish let’s for suggestions from let for permission.
- Purdue OWL’s current apostrophe guidance reinforces the broader rule that apostrophes are used in contractions and are not simply added to ordinary plural forms.
So, while there is no trustworthy current percentage to quote, the grammatical distinction itself remains standard and well documented.
Quick Checklist: How to Choose the Correct Word
Before publishing or sending your sentence, run through this checklist.
Step 1: Identify the Meaning
Ask yourself:
Am I making a suggestion?
If yes, use let’s.
Let’s start now.
Am I saying that someone or something allows an action?
If yes, use lets.
The app lets you edit photos.
Step 2: Try “Let Us”
If you can replace the word with let us, use let’s.
Let’s begin.
→ Let us begin. ✓
Step 3: Try “Allows”
If you can replace the word with allows, use lets.
She lets me borrow her notes.
→ She allows me to borrow her notes. ✓
Step 4: Check the Subject
If the sentence describes what he, she, it, or a singular noun allows, lets may be the correct form.
He lets me use his phone.
If you are suggesting something that we should do, use let’s.
Let’s use his phone.
