"Yet avoiding the heat altogether and watching Netflix from the confines of your cool couch—even while performing a perfunctory sit-up or two—is not the way to stay healthy and active this summer." — Leslie Barker, The Dallas Morning News, 13 June 2017 Did you know? Perfunctory is a word whose origins are found entirely in Latin. It first appeared in English in the late 16th century and is derived from the Late Latin perfunctorius, meaning "done in a careless or superficial manner." (Perfunctorius was also borrowed for the synonymous, and now archaic, English adjective [perfunctorious](https://www.merriam-webster.com/dictionary/perfunctorious) at around the same time.) Perfunctorius comes from the earlier Latin perfunctus, a past participle of perfungi, meaning "to accomplish" or "to get through with." That verb is formed by combining the prefix per-, meaning "through," with the verb fungi, meaning "to perform." Fungi can be found in the roots of such words as [function](https://www.merriam-webster.com/dictionary/function), [defunct](https://www.merriam-webster.com/dictionary/defunct), and [fungible](https://www.merriam-webster.com/dictionary/fungible).
