En·de·mic En·de·mic·al a.  Med.
  1. Peculiar to a district or particular locality, or class of persons; as, an endemic disease.
  Note: ☞ An endemic disease is one which is constantly present to a greater or less degree in any place, as distinguished from an epidemic disease, which prevails widely at some one time, or periodically, and from a sporadic disease, of which a few instances occur now and then.
  2. Belonging or native to a particular people or country; native as distinguished from introduced or naturalized; hence, regularly or ordinarily occurring in a given region; local; as, a plant endemic in Australia; -- often distinguished from exotic.
     The traditions of folklore . . . form a kind of endemic symbolism.    --F. W. H. Myers.
