Etymology

It is inherited from Latin ardor (“burning, heat; passion”), from ardeō (“to burn”) with the noun suffix -or.[2][3][4][5][1] Wiktionary takes it as inherited through the old language, while Nascentes calls it a learned word.[1][6]

The same Latin noun is Galician ardor, Spanish ardor, Catalan ardor, French ardeur, Italian ardore and Romanian ardoare.[7][1] The verb arder is from the same Latin root.[3]

Earliest recorded meaning

Cunha and Houaiss date the word to the 14th century.[3][2] The Crónica Troiana has it for the burning of fever: leuantou se lle hũ ardor dentro ẽno corpo “a burning rose up inside his body”.[8] The same text already has the sense “passion”, in o ardor do amor “the ardour of love”.[8]

Semantic evolution

Machado quotes a 15th-century religious text on o ardor da morte perduravel “the burning of everlasting death”.[4] The CTA corpus has the word from the Vida do Infante Josafat (witness 1431–1446) on.[9] Morais (1813) gives the heat of fire and of the sun, the heat of the climate, and figuratively the eagerness of strong passions, anger, sensuality or love, and violent desire.[10] Vieira and the modern dictionaries add the smart of a caustic or a wound and the sharp taste of pepper and spices.[11][12][13] The DLP also records the heat of a fight or argument.[13]
