means The final, climactic point that a process or series of events builds toward and ends at.

from From Latin culmen, meaning 'top' or 'summit' — the same root that gives us 'column.' The verb culminare meant literally to reach the top. It entered English through astronomy in the 1600s, describing the moment a star or planet reaches its highest point in the sky, directly overhead, before it begins to descend again. The figurative sense — the peak of an effort, a story, an argument — grew naturally from that image of a heavenly body hitting its zenith.
