Etymology

Origin of established

First recorded in 1350–1400; establish ( def. ) + -ed 2 ( def. ) for the adjective senses; establish ( def. ) + -ed 1 ( def. ) for the verb sense


Explanation

Something or someone well established is well known, totally trusted and usually has a proven track record of success. Becoming established doesn't happen overnight. You've got to put in the time and effort to prove yourself, make connections and build a good reputation. So it makes sense that this adjective is related to the verb establish, which means to "create, set up, or prove." Established is a handy word to know, especially when you're looking for a dentist — you probably won't want to try Dr. Lovedrill until his practice is more established.
