The idiom "reinvent the wheel" means to waste time and effort trying to create something that already exists or has already been done before. It refers to the idea of someone trying to create a new solution to a problem that has already been solved by someone else.
For example, if a person is trying to create a new way to make coffee, but there are already many ways to make coffee, then they are "reinventing the wheel." They are wasting their time and energy trying to create something that already exists.
This idiom is often used to discourage people from trying to create something new when there is already a solution available. It is a reminder that sometimes it is better to use what already works instead of trying to create something new from scratch.
So, if someone suggests a new idea or solution to a problem, and you know that there is already an existing solution, you can use this idiom to suggest that they are wasting their time and effort trying to create something that already exists.
