What does establish mean?
Establish is a versatile English verb meaning to set up or bring something into existence on a permanent basis. It is used when founding organizations, institutions, companies, laws, and systems: one establishes a business, a government establishes a policy, and a treaty establishes relations between nations. A second major sense concerns proof and certainty — investigators establish facts, scientists establish findings, and courts establish guilt or innocence — making the word central to legal and academic language. A related use describes securing someone's position, as when a young professional establishes herself in a field. The word carries connotations of permanence, authority, and credibility; an established practice or reputation is one that has stood the test of time. Derived forms include the adjective established and the noun establishment, which can refer both to an institution and, more broadly, to a dominant social or political elite.

When you establish something, you literally make it stand — the word traces back to Latin stabilire, "to make firm," from stare, "to stand," the same root that gives us "stable" and "state."

Etymology of establish
Establish comes from Old French establiss-, the stem of establir, which derives from Latin stabilire, "to make firm or stable," itself built on stabilis (firm) from the verb stare, "to stand." The word entered Middle English around the late 14th century, initially appearing chiefly in legal and religious contexts such as establishing laws or churches. It shares its Latin root with words like stable, stability, and state, all of which carry the underlying idea of standing firmly in place.
