The word "establish" traces back to Latin stabilire ("to make stable"), derived from stabilis (stable/firm). The prefix e- (from ex-, "out") implies bringing something into existence or visibility. Over time, the meaning expanded from physical stability (e.g., buildings) to abstract concepts (e.g., laws, reputations). The suffix -ish (via Old French -ir) marks it as a verb.
