The Latin word aptus, meaning “fit” or “suitable,” gives us the root apt or ept. Words from the Latin aptus have something to do with being fitting or suitable. Something apt fits just right into a situation. To adapt is to change in order to fit a situation better. Someone who is adept has suitable skills to perform a task well, while someone who is inept does not.
