The word "闲暇" is formed by combining the characters "闲" and "暇". "闲" consists of the radical "门" (door) and "木" (wood), historically implying a barrier that confines, thus conveying idleness or free time. "暇" includes the radical "日" (sun/day), indicating time, and the component "叚", which primarily provides phonetic value, together denoting leisure time. Both characters contribute the concept of unoccupied time, resulting in the compound meaning of leisure or spare time.
