Definition

A host is an organism that harbors a parasite or symbiont, typically providing nourishment and shelter. Think of it as a landlord providing room and board, whether willingly or not. Unlike predators that hunt, hosts are simply inhabited. The relationship can be beneficial, harmful, or neutral. A plant providing nectar to a bee is a host in a beneficial symbiosis. A person infected with a virus is a host in a parasitic relationship. 🏠

Etymology

The word "host" comes from the Old French word "oste," which means "guest" or "host." This in turn comes from the Latin word "hospes," which means both "guest" and "host." This dual meaning reflects the reciprocal relationship originally implied. It shares roots with words like "hospitality." Over time, the meaning shifted to emphasize the provider of shelter and nourishment.
