Etymology

It is inherited from Proto-Italic *feɣʷris, from Proto-Indo-European *dʰegʷʰ-ri-s, from Proto-Indo-European *dʰegʷʰ- (“to burn, warm”), according to Wiktionary and Köbler.[1][2] It is related to foveō “to warm” and februum.[1][3] The OLD calls its origin doubtful.[4] The accusative is ⟨febrim⟩ or ⟨febrem⟩, the ablative ⟨febrī⟩ or ⟨febre⟩.[4][5] Isidore derived it from ⟨fervor⟩ “heat”.[6]

Earliest recorded meaning

Köbler's first source is Plautus, whom he dates c. 250–184 BC, and Plautus has the accusative febrim.[2][5] Cato also uses it.[4]

Semantic evolution

It meant a fever, as Cicero's febrim habēre “to have a fever” and cum febrī redīre “to come home with a fever”, and with adjectives of particular fevers, as in Terence.[4][7] In Cicero Febris was worshipped as a goddess.[4]

In Ecclesiastical Latin it meant a fever.[8] British Medieval Latin described fever as marked by heat and cold, and distinguished its kinds.[9] It survives in Italian febbre, Spanish fiebre and Portuguese febre, and was borrowed into Old English as fefor, whence English fever.[1][3]
