KK: /kəmˈpætəblɪ/
In a way that is suitable or able to exist together without conflict.
The two software programs work compatibly, allowing users to share data easily.
Compatibly → It is formed from "com-" (meaning together) and "pati" (from Latin, meaning to suffer or endure). The suffix "-bly" indicates a manner. Thus, "compatibly" means in a manner that can endure or exist together harmoniously.
Think of 'together' ('com-') and 'enduring' ('pati') to remember that 'compatibly' means existing together in harmony.
