Word Origin for Host
"person who receives guests," late 13c., from Old French hoste "guest, host, hostess, landlord" (12c., Modern French hôte), from Latin hospitem (nominative hospes) "guest, host," literally "lord of strangers," from PIE *ghostis- "stranger" (cf. Old Church Slavonic gosti "guest, friend," gospodi "lord, master;" see guest). The biological sense of "animal or plant having a parasite" is from 1857.
"multitude" mid-13c., from Old French host "army" (10c.), from Medieval Latin hostis "army, war-like expedition," from Latin hostis "enemy, foreigner, stranger," from the same root as host (n.1). Replaced Old English here, and in turn has been largely superseded by army. The generalized meaning of "large number" is first attested 1610s.
"body of Christ, consecrated bread," c.1300, from Latin hostia "sacrifice," also "the animal sacrificed," applied in Church Latin to Christ; probably ultimately related to host (n.1) in its root sense of "stranger, enemy."
"to serve as a host," early 15c., from host (n.1). Related: Hosted; hosting.
- The larger of two organisms in a symbiotic relationship.
- An organism or cell on or in which a parasite lives or feeds.♦ A definitive host is an organism in which a parasite reaches sexual maturity. The anopheles mosquito is the definitive host for the malaria plasmodium because, while the mosquito is not adversely affected by the plasmodium's presence, it is the organism in which the plasmodium matures and reproduces.♦ An intermediate host is an organism in which a parasite develops but does not attain sexual maturity. Humans and certain other vertebrates are the intermediate host of the malaria plasmodium.♦ A paratenic host is an organism which may be required for the completion of a parasite's life cycle but in which no development of the parasite occurs. The unhatched eggs of nematodes are sometimes carried in a paratenic host such as a bird or rodent. When a predator eats the paratenic host, the eggs are ingested as well.
