The Chinese word **间隔** (jiàngé) is a compound noun formed by combining two semantically similar characters: **间** (jiān), which originally signifies a gap, space, or betweenness, and **隔** (gé), which means to separate, partition, or divide. Together, they create a cohesive concept where each character reinforces the other, resulting in a meaning that emphasizes a defined space of separation—an **interval**, a **gap**, or a period of time between events. This is a classic example of a parallel or coordinative compound in Chinese morphology, where two elements of analogous meaning are joined to express a single, more precise or nuanced idea.
