Apex
noun /ˈeɪpɛks/ — The pointed tip — the highest, sharpest, most extreme point of anything.
Definition
The top or highest point of something, especially one forming a point; the culmination or climax of something.
Beyond the definition
Apex has a precision that summit lacks — a summit is broad enough to stand on; an apex is a point. The apex predator, the apex of one's career, the geometric apex: all share the quality of being the sharpest version of the thing.
Origin & history
From Latin apex — peak, tip (the pointed top of the Roman flamen's headdress). The very tip — not the broad top but the single sharpest point.
