Key Differences
Apex is used to describe the peak or the highest point of an achievement, a process, or a physical object. It symbolizes the pinnacle of success or elevation. On the other hand, nadir refers to the lowest point or phase, either in a situation, a career, or on a celestial sphere directly opposite the zenith.
While the apex often embodies culmination, climax, or a point of greatest strength or vigor, nadir represents the bottom, the point of greatest adversity or despair. This contrast illustrates how both terms are used to articulate extremities in various contexts, from literature to astronomy.
In astronomy, the apex refers to the point in the sky directly above an observer, the zenith, or the highest point in the celestial sphere’s apparent path. Conversely, nadir is the point directly beneath the observer, diametrically opposed to the zenith, highlighting how these terms are also used to describe specific astronomical positions.
In the realm of personal achievements or business, reaching the apex is often associated with reaching the peak of one's career or the highest level of performance. In contrast, hitting the nadir implies a critical low point, often prompting a need for significant change or reflection.
In literature and storytelling, characters often face their nadir as a pivotal moment of failure or challenge, which is essential for the narrative arc. The apex, meanwhile, is typically the moment of triumph or the climax of the story, underscoring the narrative importance of both extremes.

The nadir (; also UK: ; Arabic: نظير, romanized: naẓīr, lit.
