Forms

mortal m or f (plural mortais, comparable, comparative mais mortal, superlative o mais mortal or mortalíssimo)[1] Medieval texts have the plural mortaes (1271) and mortaaes (14th century), and the singular is also spelt mortãl and mortall in the 15th century.[2]

Etymology

It is inherited from Latin mortālis (“subject to death, mortal”), written Old Galician-Portuguese mortal in the oldest texts.[2][3][1] The Latin adjective is formed mors (“death”) with the suffix -ālis.[1][4] Nascentes counts the Portuguese word a learned one, taken over from the written language.[5] Seen from Portuguese, it is morte with the suffix -al.[1]

The same Latin word is Galician mortal, Spanish mortal, Catalan mortal, French mortel, Italian mortale and Romanian mortal.[6][1]

De Vaan places the noun among the derivatives of morior (“to die”), from Proto-Indo-European *mr̥-ti- (“death”), built on the root of *mer- (“to die”).[7][1]

Earliest recorded meaning

Houaiss dates the plural mortaes to 1271, from the slips of Cunha's index of medieval Portuguese.[2] In the Cantigas de Santa Maria the adjective qualifies feelings and wounds rather than people: coyta mortal “deadly grief”, medo mortal “mortal fear”, chagas mortaes “deadly wounds”, and pecado mortal “mortal sin”.[8] The Crónica Troiana speaks of a battle that was estrayo… et mao et mortal, “fierce, cruel and deadly”.[8]

Semantic evolution

Both Latin senses, “subject to death” and “causing death”, came into Portuguese together.[2][4] The religious pecado mortal, a sin that brings the death of the soul, continues a Medieval Latin use of the word.[8][9] The cantigas d'escarnho also use mortal as an adverb, “mortally”.[8][10]

Cardoso's dictionary of 1569 gives only the Latin equivalent and Pereira (1697) defines it as “that brings death”, while Bluteau (1712) separates the being that can die from the thing that kills, and Folqman (1755) records ódio mortal and inimigo mortal for a deadly hatred and a sworn enemy.[11][12][13][14] The modern dictionaries add the weakened senses “fleeting”, “dying” and “unbearably tedious”, and use the noun for a human being and, in the plural, for mankind.[2][15][16] From salto mortal the noun also names a somersault in gymnastics and in capoeira.[2][1]
