Etymology

Origin of professional

First recorded in 1740–50; profession + -al ¹

Explanation

When an athlete "goes pro," she goes professional–-she is paid for her service rather than doing it on an amateur basis. Other professionals, including doctors and lawyers, are also paid for their work, which, we hope, they conduct in a professional manner. In the 15th century, the word profession referred to vows taken upon entering a religious order. A monk or priest professed his faith. Now, the word suggests competence and expertise and even dignity––"He can't ask me to go out for coffee. I'm a vice president. That just wouldn't be professional!"
