English Idiom – Square the circle

Meaning – To try to do something that is impossible. An attempt to do something that is extremely difficult and is unlikely to be successful.

This idiom references an ancient geometry problem – the challenge of constructing a square with the same area as a given circle by using only a finite number of steps with compass and straightedge (ruler). This problem was found to be impossible to solve, therefore this expression became a metaphor for trying to do the impossible.

If you go back to square one on something you are starting again.
