The word "巅峰" is formed by combining two characters, each meaning "peak" or "summit". The character "巅" consists of the radical "山" (mountain) indicating its category, with the component "顛" providing phonetic clues, meaning the top of a mountain. The character "峰" also uses the radical "山" for meaning, combined with "夆" for sound, specifically denoting a mountain peak. Together, they create a compound word where both characters semantically reinforce the concept of the highest point, used literally for physical peaks or metaphorically for pinnacles of success.
