Not too surprisingly, febrile originatedin the field of medicine. We note its first use in the work of the 17th-century medical reformer NoahBiggs. Biggs used it in admonishingphysicians to care for their “febrilepatients” properly. Both feverish and febrile are from the Latin word for fever, which is febris. Nowadays, febrile is used in medicine in a varietyof ways, including references to suchthings as “the febrile phase” of an illness. And, like feverish, it also has an extended sense, as in “a febrileemotional state.”
