高得没有底也望不到顶So high it has neither floor nor ceiling
下峥嵘而无地兮，上寥廓而无天。
Below, the crags fall away with no ground; above, the emptiness has no sky.
楚辞 · 远游· our translation
Here 峥嵘 is height with no ground beneath and no sky above: a name takes the unusualness of that, not just the height.
「峥嵘」在这里是高得下面没有地、上面望不到天——名字用「峥」，取的是这个「高得不寻常」。
峥嵘峥嵘岁月峥之峥然峥宇子峥
In a name
峥 is not steadiness but unusual height — it carries an edge.
