watershed

What does "watershed" mean?
A watershed is an event, period, or point in time that marks a major turning point or a significant shift in the course of history, development, or a personal narrative. The image is that of a ridge or divide where water begins to flow into an entirely different direction or river system, representing a clear separation between what came before and what follows. In professional or academic contexts, it is commonly used to describe breakthroughs, legislative changes, or scientific discoveries that fundamentally alter a landscape. It carries a sense of gravity and finality; once a "watershed moment" occurs, the situation rarely returns to the previous state.
