What does established mean?
"Established" is an adjective describing something that has been in existence long enough to be firmly set up, recognized, and generally accepted. An established company has proven itself over time; an established fact is universally acknowledged; an established practice is one that people follow by convention. The word carries strongly positive connotations of reliability, credibility, and permanence, which is why it appears so often in business, academia, law, and journalism — phrases such as "a well-established reputation" or "an established leader in the field" signal trustworthiness without needing further proof. It can also describe physical settling, as when a newly planted tree becomes established and grows independently. Derived from the verb "establish," which traces back through Old French to the Latin stabilire, meaning to make firm or stable, the word shares its ancient root with "stable," "state," and "status." Its opposite sense would be something unproven, tentative, or newly founded.

Every "established" tradition was once brand new — the word itself comes from the Latin stabilire, to make stand firm, which is why stability and established share a root.

Etymology of established
"Established" derives from "establish," which entered English from Old French establiss-, the stem of establir, ultimately from the Latin stabilire, meaning "to make firm or stable." That Latin verb comes from stabilis (firm, steadfast), built on the root stare, "to stand." The same root gives English cognates such as "stable," "state," "status," and "institute." The adjectival use of "established," describing something long-settled and recognized, developed naturally from the past participle of the verb.
