Etymology

The noun “death” is inherited from Old French mort, inherited from Latin mors (“death; capital punishment”), accusative “mortem”.[4][5][1][3][6] Like the verb “morī” (see mourir), it goes back to the Indo-European root Proto-Indo-European *mer- (“to die”).[5] In Latin “mors” also named Death personified and, figuratively, ruin or loss (“mors memoriae” “loss of memory”); Christian Latin used it for spiritual death through sin.[5]

Cognate with Italian morte and Spanish muerte.[3]

Earliest recorded meaning

It is first found in the Séquence de sainte Eulalie (881), which asks that Christ have mercy on us post la mort “after death”.[4][5]

Semantic evolution

Phrases appear early: aler a la mort (late 10th century), a mort (1080, a mort est ferut “he is mortally wounded”), ne por vie ne por mort (1160–1174) and u a mort u a vie (about 1170), forerunner of mort ou vif.[4][5] Death personified, with a club or a sling, is found from about 1165, before the familiar scythe.[4][5] In law mort d'homme dates from 1283, and the death penalty is meant in the 14th century, condamné à mort (1606) replaced criminel de mort (1559).[4][5]

From the end of the 12th century mort also meant spiritual death, damnation, with the seconde mort of the Apocalypse (about 1223).[4][5] The oath par la mort Dieu (late 13th century) was disguised as morbleu.[5][3] Modern phrases include il n'y a pas mort d'homme (1838) and c'est pas la mort (1970s).[5]

Forms

mort (feminine morte, masculine plural morts, feminine plural mortes)[2]

Etymology

The adjective “dead” is inherited from Vulgar Latin *mortus (“dead”), the popular form of classical Latin mortuus (“dead”), past participle of morior (“to die”).[3][1][2][8] Littré notes that “mortuus” is irregularly formed, with the suffix of “mutuus”; the regular form would have been “mortus”.[9] The noun “un mort”, “une morte” “dead person” is the adjective used as a noun (1080).[1]

Cognate with Italian morto and Spanish muerto.[3]

Earliest recorded meaning

It is first found at the end of the 10th century, as the participle and adjective of mourir; the noun un mort “a dead man” follows in 1080.[1][10]

Semantic evolution

Besides people, animals and plants (bois mort, feuilles mortes), the adjective was applied to whatever has lost its life or movement: stagnant water (morte-eau, 1690), a dead season (morte-saison, 15th century).[7][3][10] Mort-né dates from 1551 and mort-bois from 1533.[3] Card players have said faire le mort, of the hand laid down by a missing player, since 1845.[11]
