Expeditious is an adjective that means done with speed and efficiency.

Our word of the day comes from the Latin word expedire (eks ped ARE ay) which means ‘to liberate.’ By the late 15th century, its definition had shifted to its current meaning. It may be helpful to think of expeditious as a synonym of words like ‘swift’ and ‘prompt.’ Here’s an example:

While I can’t say I was a fan of the food that diner served, I did appreciate the expeditious service. The place may have been lousy, but at least, their prompt delivery got me in and out quickly.
