Reaching a peak, climax, or final point; bringing something to its highest point or conclusion.
From Latin 'culminare,' meaning to reach the top, from 'culmen' (summit or peak). The word entered English in the 17th century, originally used in astronomy, then expanded to general use.
The word 'culminate' has an astronomical birth—it originally described when a star reached its highest point in the sky! That's why the word still has that sense of reaching a peak, like you're aiming for the very top of something.
