What Does Let’s Mean?

The word let’s is a contraction of the phrase “let us.” It is used when making suggestions, proposing actions, or inviting others to do something together.

• Let’s order dinner.
• Let’s start the meeting.
• Let’s study together.
• Let’s finish this project.

In every example above, let’s can be replaced with “let us.”

For example:
