The more the merrier means that a situation becomes more enjoyable when more people join in. It is often said when welcoming others to take part in an activity, gathering, or event.

The saying has been used in English for hundreds of years and reflects the idea that shared company brings more fun and happiness. It became a common friendly expression when inviting others to join a group.

When another cat jumped onto the couch beside the others, she laughed and said the more the merrier.
