Etymology tree
From the same root
Forms
febre f (plural febres)[1] The 13th-century texts write fever and febre; the Galician Miragres de Santiago have feuere.[2][3]
Etymology
It is inherited from Latin febris (“fever”), written Old Galician-Portuguese fever and Old Galician-Portuguese febre in the oldest texts.[2][4][1] Nascentes derives it from the accusative ⟨febrem⟩, not ⟨febrim⟩, through the old form with ⟨v⟩, ⟨b⟩ returning through the medieval wavering between /b/ and /v/.[5][6]
The same Latin word is Galician febre, Spanish fiebre, Catalan febre, Occitan fèbre, French fièvre and Italian febbre.[7][8] Corominas regards the Spanish form as semi-learned, the word of physicians, beside the popular calentura.[9]
The Latin noun goes back to *feɣʷris and to Proto-Indo-European *dʰegʷʰ- (“to burn”), meaning “burning”; its cognate is Ancient Greek τέφρα (téphra, “ashes”).[10][1] Figueiredo (1899) took it as a metathesis of ⟨ferbis⟩, from ferveō (“to boil”).[11]
Earliest recorded meaning
The Cantigas de Santa Maria tell of one who dũa forte fever mui cedo morreu “soon died of a strong fever”, and elsewhere of a fever aguda and a fever mortal; cantiga 235 already writes febre gẽeral “fever all over the body”.[3][12] The sense is the illness with raised body heat.[3]
Semantic evolution
The old dictionaries describe fever in the humoral terms of their time: Bluteau as a preternatural heat of the blood and humours spreading from the heart.[13] Barbosa (1611) has febrezinha “slight fever” and ter febre “to have a fever”.[14] Morais (1813) distinguishes continuous and intermittent fevers.[15]
Figurative senses, “great agitation of the mind” and “burning desire” (febre do ouro “gold fever”), are given by Figueiredo and the modern dictionaries.[11][2][16] Many diseases are named with the word: febre amarela “yellow fever”, febre aftosa “foot-and-mouth disease”, febre tifoide.[2][1] In the plural, informally, febres is malaria, and Portuguese country people use o febre and a febre for different kinds of fever.[2][17]

Usage notes
Houaiss and Cunha record a separate adjective febre “underweight” (of a coin, lacking its legal weight), first found in 1372, which Houaiss explains as an old divergent form of flébil from Latin flebilis “weak”, probably influenced by French faible;[2][4][11][16][21] Cunha, Figueiredo and Aurélio derive it from the French word, and the REW from the French word through Spanish.[2][4][11][16][21] Viterbo explains moeda febre as the opposite of moeda forte.[22] The Crónica Troiana uses it for “weak”: molleres mansas et febres “meek and weak women”.[12]
