Forms

endormir[1]

Etymology

It is inherited from Latin indormīre (“to sleep on; to be careless”),[2][3][4][5][6] which in Late Latin also meant “to go numb” (of a limb); the Latin verb is formed from in- and dormiō (“to sleep”) (see dormir).[2][3] The Grand Robert adds that the French verb was shaped after the simple verb, and the GLLF and Littré simply analyse it as en- and that verb.[5][7][8]

Compare Old Occitan endormir and Italian indormire.[8]

Earliest recorded meaning

The Chanson de Roland (about 1100) has the past participle: Endormiz est, ne puet mais en avant “he is asleep, he can go no further”.[2][8]

Semantic evolution

The reflexive s'endormir “to fall asleep” is in the Couronnement de Louis (about 1135).[2] Chrétien de Troyes's Cligès (1176) uses the feminine andormie for a sleeping draught, later (1572) a name of henbane.[2][3] The Livre des Rois (about 1170) has endormi “numb”, of an arm tired from striking, and Benoît de Sainte-Maure (about 1175) the figurative “to lull, deceive” (od beiau parler endormir).[2][8]

S'endormir “to die” dates from the 13th century and survives in literary phrases; the slang endormir “to kill” (Vadé, 1753) has gone.[2][3] In the 16th century the reflexive meant “to lose one's force” (Gringore, before 1539) and “to subside”, of a feeling (Belleau, before 1577), and Montaigne (1580) has endormir un mal; in medicine the verb is used of inducing sleep (before 1577; revived in the 19th century).[2][3] Boileau (1660) uses it for boring an audience.[2][3]
