Homonym: reserve (Backup)
A "reserve" refers to a supply of resources or assets that are set aside for future use. This can include financial reserves, such as savings or investments, which individuals or organizations keep to ensure they have funds available for emergencies or unexpected expenses.
In environmental contexts, a reserve often describes a protected area designated for conservation, such as a nature reserve or wildlife reserve. These areas are established to preserve biodiversity, protect endangered species, and maintain natural habitats, allowing ecosystems to thrive without human interference.
