助記提示
1、vert- + -ex.
2、字面含義：that which turns, the turning point. => whirling column, whirlpool. => highest point, the point opposite the base in geometry.
3、其原始含義或者說最初含義為：whirling column, whirlpool. 也就是：漩渦，漩渦所涌出的漩渦柱；想象一下升起的漩渦柱頂端的頂點。再想象一下咱們物理學(xué)中的“鐘擺模型”，其自由轉(zhuǎn)動只會低于其中心的轉(zhuǎn)動點。
4. 轉(zhuǎn)折點---頂點就是發(fā)生轉(zhuǎn)折的點。
