“Adroit” is a loanword borrowed directly from French. In French, “à droit” is translated as “according to the right” or “properly,” but in English, “adroit” is an adjective that can refer to either physical or mental dexterity. It means someone is performing a task in a quick and skillful manner. An adroit researcher might come up with the perfect solution to a vexing problem, or an adroit dancer might show off ease of movement.
