adjective nos·o·co·mi·al \ˌnä-sə-ˈkō-mē-əl\

Definition of nosocomial

  1. :  acquired or occurring in a hospital <nosocomial infection>



Did You Know?

Nosocomial is a word that usually occurs in formal medical contexts; specifically, in reference to hospital-acquired sickness. We hope you never encounter "nosocomial" as part of your own medical diagnosis, but if you do, you might want to remember that the term descends from "nosocomium," the Late Latin word for "hospital." "Nosocomium" in turn traces to the Greek nosos, meaning "disease." That root has given English other words as well, including "zoonosis" ("a disease communicable from animals to humans under natural conditions") and "nosology" ("a classification or list of diseases" or "a branch of medical science that deals with classification of diseases").

Origin and Etymology of nosocomial

Late Latin nosocomium hospital, from Late Greek nosokomeion, from Greek nosokomos one who tends the sick, from nosos disease + -komos; akin to Greek kamnein to suffer, toil, Sanskrit śāmyati he tires


First Known Use: circa 1843
