If you have ever paused over your keyboard trying to figure out the rules for lets vs let’s, the short answer is actually quite simple: “let’s” is used to make a shared suggestion, while “lets” is an action word that means to give permission. That tiny little apostrophe completely changes the job the word is doing in your sentence. It is an incredibly common mix-up in English—even native speakers accidentally swap them when typing fast! Don’t worry if it still trips you up. We are going to walk through exactly how to tell them apart, including a foolproof memory trick you can use every single time you write.
Lets vs Let’s: What You Need to Know
“Let’s” is a contraction of the words “let us.” You use it when you are suggesting an activity or proposing an idea to someone else, such as “Let’s grab a cup of coffee.”
“Lets” is the third-person singular present tense form of the verb “let.” It means to allow, permit, or give permission, like in the sentence, “My boss lets me leave early on Fridays.”
What Does “Lets” Mean?
“Lets” is an action word. Specifically, it is the present tense verb you use when talking about he, she, it, or a single noun.
Because it follows the standard grammar rules for third-person singular verbs, we add an “s” to the end of the base verb “let” just like we do with words like run (runs) or eat (eats). You use this word to express that someone or something is giving permission. When a security guard opens a gate, he lets you inside. When a software update removes restrictions, it lets you do more on your phone.
What Does “Let’s” Mean?
“Let’s” with an apostrophe does a completely different job. It combines the words “let” and “us” into one short word.
You use this when you want to invite the person you are talking to into a shared action. Even though it literally means “let us,” native English speakers rarely say the full phrase “let us” unless they are speaking in a highly formal setting. In everyday conversation, “let’s” is the standard, natural way to make a friendly suggestion.
Difference Between Lets and Let’s
The difference comes down to the subject of your sentence and what you are trying to communicate.
“Lets” points to an outside person or thing giving permission. The subject is usually a person (like a teacher), an object (like a key), or a pronoun (he, she, it).
“Let’s” involves you and the listener. The apostrophe physically takes the place of the letter “u” in “us.” It operates as a suggestion rather than a statement about permission.
A Simple Memory Trick
Look closely at the word let’s. Imagine that tiny apostrophe is a little hook pulling you and your friend together to do an activity.
If you are ever stuck while writing, try separating the word into “let us.” Read your sentence out loud. If “let us” makes perfect sense, you need the apostrophe. If “let us” sounds strange or incorrect, leave the apostrophe out.

Common Mistakes to Avoid
Mistake: The teacher let’s the students talk quietly during group work.
Correction: The teacher lets the students talk quietly during group work. (The teacher allows them to talk; “let us” does not make sense here.)
Mistake: Lets go to the cinema tonight.
Correction: Let’s go to the cinema tonight. (You are suggesting an activity to do together.)
Mistake: My brother never let’s me borrow his car.
Correction: My brother never lets me borrow his car. (He does not give permission.)
Mistake: If you are feeling tired, lets just stay home.
Correction: If you are feeling tired, let’s just stay home. (You are proposing a shared plan.)
Tips for Remembering the Differences
Check for the “allow” meaning: If the word can be swapped with “allows” or “permits,” write lets.
Do the “us” test: If you can swap the word with “let us,” write let’s.
Look at sentence position: Let’s very often starts a sentence or a new clause. Lets usually sits right in the middle, directly following a noun or pronoun.
Spot the missing letter: Remind yourself that the apostrophe is literally standing in for the letter “u”.
