The word 原地 is formed by combining two independent characters, each contributing its core meaning to create a new, unified concept. The first character, 原 (yuán), carries the fundamental idea of "original", "source", or "primary". The second character, 地 (dì), means "ground", "earth", or "place". When fused, they create a spatial concept meaning "the original place" or "the very spot", where the sense of 原 modifies and specifies the nature of the 地, emphasizing a fixed, unchanged location from which something begins or upon which something stands.
