Forms

désarmer[1]

Etymology

It is formed from French dés- + armer, already in Old French as desarmer.[2][3][1] The verb armer is from Latin armō (“to equip, arm”).[4] Compare Old Occitan desarmar, Spanish desarmar and Italian disarmare.[5]

Earliest recorded meaning

It first appears in the Chanson de Roland as a reflexive verb, “to take off one's arms or armour”: Icele nuit ne se velt desarmer “That night he would not take off his armour”.[2][5] The TLFi dates the text to 1100, the Grand Robert, the GLLF and Bloch–Wartburg to 1080.[2][3][6][4] In Old French it could also mean “to strip, undress”.[3][7]

Semantic evolution

From the 12th century it meant to take someone's weapons away.[8] A ship that is désarmé has been laid up, the opposite of armer a ship, from 1466; the verb is used intransitively from 1701 and of sailors, “to be discharged”, from 1773.[8] In fencing it is to strike the sword from the opponent's hand (1718).[8]

Figurative uses follow those of armer: Montaigne writes désarmer l'injure in 1588,[2] and with a person as object it means “to soften, make yielding”, recorded in Racine in 1664 according to the TLFi and in Corneille in 1640 according to Rey.[2][8] Intransitively it meant “to stop keeping up a war footing” (1681, Vaugelas),[2] while since the mid-19th century it has meant “to give up”, mostly in the negative, as in sans désarmer.[8] The noun désarmement is recorded in 1594.[4]
