Of Apogees, Climaxes, and Culminations

Apogee is often used in its figurative sense, signifying the high point of a career, endeavor, or state (“she was at the apogee of her profession”). This meaning developed as a metaphorical extension of the word’s astronomical sense, denoting the farthest distance from earth of an object orbiting the planet.

A number of other English words that are synonymous with apogee have followed a similar path of figurative development from a technical meaning. Climax (“the most interesting and exciting part of something”) came into English as a term for a series of phrases arranged in ascending order of rhetorical forcefulness. And, very much like apogee, culmination (“the final result of something”) is also rooted in astronomy: it originally referred to the highest point a celestial body reaches in its daily revolution (for example, the sun’s height at noon).
