Tipping point is often used to describe a critical moment or turning point in a process or situation. However, there are several synonyms that can be used to communicate this same idea. One such synonym is breaking point, which signifies a point where something can no longer be sustained or endured. Another alternative is critical mass, implying a threshold of a quantity or activity that causes an irreversible change. Turning point is also a viable synonym, suggesting a decisive moment or event where a change occurs. Finally, threshold itself can be a synonym, representing a point at which significant change can occur.
