The word 假期 is formed by combining two conceptual building blocks: 假, which carries the inherent idea of a break, leisure, or a temporary suspension of normal activities (like work or school), and 期, which means a fixed, bounded period of time. When placed together, these characters conceptually merge to define a specific, limited duration specifically designated for rest or leisure, essentially painting a complete picture of a "holiday" or "vacation" as a bounded break from routine.
