Another similar word is καταστρέφω (katastrephō) [ka-ta-STRE-pho], meaning “to overturn” or “to subvert,” which suggests a more violent or radical action than the sometimes more peaceful dissolution suggested by καταλύω.

Further Insights: The verb καταλύω (katalyō) can refer to both physical and metaphorical actions. It can mean to destroy a physical structure, to nullify a law, or to break something down in a more abstract sense. This word is also used in contexts indicating rest or temporary lodging, showing its versatility in meaning.
