Etymology
It is inherited from Middle English mortal, borrowed from Old French mortal (also mortel (“destined to die”)) and directly Latin mortālis (“subject to death”),[2][3][4] from mors (“death”) (stem mort-),[2][3] from Proto-Indo-European *mer- (“to rub away, harm; to die”),[3][4] also the source of Ancient Greek βροτός (brotós, “mortal”).[4]
Earliest recorded meaning
Subject to death: about 1374 in the OED, about 1380 in Barnhart; deadly or grievous about 1370 in Barnhart; all first found in Chaucer.[5][2]
Semantic evolution
Causing death, deadly, is from about 1385,[5] now used only of diseases and wounds.[5] Of a sin, deserving damnation, it is from the 15th century.[4] Trench notes that the active sense, deadly, has nearly departed from mortal, while the passive has departed from deadly.[6] The noun, a human being in contrast with an immortal, is from 1567,[5][3] used playfully for a person from 1718.[5] As an intensive, every mortal thing, it is colloquial and dialectal.[7][8]
