adjective en-DEM-ik

What it Means

When used for a plant or animal species, endemic describes something that grows or exists in a certain place or area, and often specifically something restricted to a particular locality or region. Endemic is also used to describe diseases that persist over time in a particular region or population. It can also mean “common in a particular area or field.”

// Our children were excited to finally see wild giant pandas—endemic to just three provinces in south-central China—during our family vacation.

// He eventually learned that low wages were endemic to his line of work, but he continued nevertheless to pursue his passion.

Endemic in Context

“Though less charismatic than the improbably pastel pink birds, unique endemic plants have achieved impressive feats of resourcefulness and endurance. Indeed, scientists have called the region an ‘unparalleled natural laboratory’ to understand how plants adapt to ‘extreme environmental conditions.’” — Thea Riofrancos, Extraction: The Frontiers of Green Capitalism, 2025

Did You Know?

Ever wonder how endemic ended up in the English language? It arrived via French and New Latin, with its ultimate origin likely in the Greek adjective éndēmos, which describes (among other things) a disease confined to one area. Éndēmos was formed from en- ( “in”) and a form of the noun dêmos, meaning “district, country, people.” That word was also key to the formation of the earlier word on which éndēmos was modeled: epidēmia, meaning “disease affecting a large number of individuals.” English adopted epidemic (also via French) in the early 17th century, but endemic didn’t become, uh, endemic until a century and a half later. (The familiar relation pandemic slipped into the language in the mid 17th.) In current use, endemic characterizes diseases that are generally found in a particular area—malaria, for example, is said to be endemic to tropical and subtropical regions—while epidemic indicates a sudden, severe outbreak within a region or group. Endemic is also used by biologists to characterize plant and animal species that are found only in a given area.
