Forms

mortal m or f (masculine and feminine plural mortales)[1]

Etymology

It is inherited from Latin mortālis (“subject to death, mortal”).[2][3][4][1] The DCECH calls the old Old Spanish mortaldad “plague” the popular counterpart of mortalidad, and derives mortandad from it.[2]

The same Latin word is Portuguese mortal, Catalan mortal, French mortel and Italian mortale.[5][1] Nascentes regards the Portuguese word as learned.[6]

The Latin adjective is formed from mors (“death”) with the suffix -ālis.[7][1] The noun goes back to Proto-Indo-European *mértis (“death”), from the root *mer- (“to die”), which also gave morior (“to die”).[1][8]

Earliest recorded meaning

The first record is the Auto de los Reyes Magos, which the CDH dates about 1180 and the DCECH about 1200: the kings wonder how to test whether the child is homne mortal, “a mortal man”, an earthly king or a heavenly one.[9][2][10] The sense “deadly” follows in the Vida de Santa María Egipcíaca (c. 1215), where the speaker prays for her llagas that son mortales, “mortal wounds”.[9]

Semantic evolution

Alfonso X's prose uses it for what must die, what causes death and what concerns death, and as a noun for human beings, los mortales.[11] Autoridades added the sense of feelings that wish another's death, as in odio mortal and enemistad mortal.[12] The Academy recorded quedarse mortal “to look like death” in 1817, and in 1843 the sense “excessive, very long”, as in cuatro leguas mortales.[13][14]

The modern dictionaries add the colloquial sense “very intense”, as in un frío mortal.[15][16] In Nicaragua, Cuba, Bolivia, Paraguay, Chile and Uruguay mortal can mean “excellent”, and in Cuba it describes a friendly, helpful person.[17]
