Usage

What does endemic mean? Endemic is an adjective that means natural to, native to, confined to, or widespread within a place or population of people. Endemic is perhaps most commonly used to describe a disease that is prevalent in or restricted to a particular location, region, or population. For example, malaria is said to be endemic to tropical regions. In this context, it can also be used as a noun: an endemic disease can simply be called an endemic. When used to describe species of plants or animals that are found only within a specific place, it has the same meaning as native or indigenous, as in This plant is endemic to this region. It can also be applied to characteristics of a people, place, or situation, as in Corruption was endemic in that organization when I worked there.

Etymology

Origin of endemic

First recorded in 1655–65; from New Latin endēmicus, equivalent to Greek éndēm(os) “dwelling in a place, native, (of disease) endemic” (from en- “within, in” + dêm(os) “people, district”) + Latin -icus adjective suffix; en- ², deme, -ic

Explanation

If you want to underscore just how commonly found and present something is within a particular place, try the word endemic. The saguaro cactus is endemic, or native, to the American southwest — so watch out for its sharp spines when you're hiking in Arizona! Although endemic meaning "prevalent" often describes a plant or disease, it can also refer to something less tangible and more unwanted such as violence or poverty. Many complain of endemic corruption in the local government. Despite its -ic ending, endemic can also be used as a noun to signify a plant or animal that is prevalent in a certain region. If an endemic is brought to another area which it takes over, destroying the local population, it's classified as an invasive species.
