The word 收留 is a compound verb formed by combining two characters: 收 (shōu), meaning "to receive", "to take in", or "to collect", and 留 (liú), meaning "to stay", "to remain", or "to keep". Together, they create a semantic synergy where 收 provides the action of accepting or admitting someone, and 留 adds the crucial dimension of allowing that person to remain or stay on. Thus, the compound conveys the specific, compassionate meaning of "to take someone in and provide shelter or care", typically referring to offering refuge to a person in need, such as a homeless individual, a refugee, or a stray animal. The formation follows a common Chinese morphological pattern where two verbs with related meanings combine to express a single, more nuanced action.
