When a star or other heavenly body culminates, it reaches its highest point above the horizon from the vantage point of an observer on the ground. Culminate was drawn from Medieval Latin culminare, meaning "to crown," specifically for this astronomical application. Its ultimate root is Latin culmen, meaning "top." Today, the word’s typical context is less lofty: it can mean “to reach a climactic point,” as in “a long career culminating in a prestigious award,” but it can also simply mean "to reach the end of something,” as in “a sentence culminating in a period.”
