The Chinese word **住宿 (zhùsù)** is a compound noun formed by combining two semantically related characters: **住 (zhù)**, meaning "to reside" or "to live," and **宿 (sù)**, meaning "to lodge" or "to stay overnight." Together, they create a single term that conceptually narrows and specifies the general idea of "staying" into the more concrete concept of "accommodation" or "lodging," where one resides temporarily, such as in a hotel or dormitory. This formation follows a common pattern in Chinese where two near-synonyms are paired to form a precise, cohesive word.
