mors m (invariable)[1]

Etymology

It is inherited from Latin morsus (“a bite”), the verbal noun of mordeō (“to bite”), the source of mordre.[2][3][4][5] The word morceau is a diminutive of it.[2][3]

Cognate with Italian morso and Old Occitan mors (“bite”).[4][6]

Earliest recorded meaning

It is first found about 1120 in the Voyage de saint Brendan, meaning a bite, the act of biting.[2][3]

Semantic evolution

As the action noun of mordre, mors meant “bite” into the 16th century (the TLFi has it until Monet in 1636), and it also meant a morsel, a mouthful bitten off (1176), a sense now kept only by its derivative morceau.[2][3][4] The derivative morsure (1213) then took over the sense “bite”.[3][4]

From the idea of something that bites or holds, mors named technical objects: the clasp that held a cope on the breast (about 1160), and above all the bar of the bridle in a horse's mouth (1370).[2][3][4] From it came prendre le mors aux dents (1547), said of a horse, and figuratively, from 1694, to set to work with energy;[3][2] Old French already said prendre le frein as dents with the same idea.[3][2] The jaws of a vice (mords d'étau, 1680) and the joint of a bookbinding (1765) followed, and mors du diable named the scabious (1573).[3][2]
