The kanji 催 is a phono-semantic compound (形声文字, けいせいいもじ). The left side is a radical called 亻(にんべん, ninben), representing "person." The right side is 崔 (さい, sai), which provides the phonetic component. The original meaning of 崔 is related to "high" or "a peak," and when combined with the "person" radical, it subtly shifted to imply "to urge" or "to encourage" someone to reach a certain height (metaphorically). The character's formation thus combines a semantic element (person) with a phonetic element (sound).
