¿QUÉ SIGNIFICA: "GROUNDBREAKING"?
This is an expression that if I heard a Spanish speaker use it, I would be impressed. It is not commonly used but can be heard in the business sector from time to time (de vez en cuando).
So what does it mean? Well, if something is "groundbreaking" it means that it is very innovative and unique. A good example of this is when the first iPhone was produced and it became clear that it was a "groundbreaking" product.
Hope that helps!
