Forms

insomnie f (plural insomnies)[1]

Etymology

It is borrowed from Latin īnsomnia (“sleeplessness”),[2][3][1][4] the neuter plural of īnsomnium, from īnsomnis (“sleepless”),[4][5] formed from in- (“not”) and somnus (“sleep”).[4][6][7][8] The Latin noun belongs to the Indo-European root Proto-Indo-European *swep- (“to sleep”), also behind sommeil and somme3.[4][5]

Middle French had earlier taken insompnité (1495) from Late Latin insomnietas, a 4th-century derivative.[2][4]

Earliest recorded meaning

Bloch–Wartburg and the GLLF date it to 1555, in Belon; the TLFi's first quotation is from André Du Chesne in 1611, for “lack of sleep”.[3][7][2]

Semantic evolution

It kept the Latin sense, involuntary lack of sleep, and is now more often used of a time during which one cannot sleep, especially in the plural.[4][9][7] Richelet noted in 1680 that physicians sometimes made it masculine, after Latin insomnium.[4] Its derivatives are insomnieux (1853, the Goncourts) and the commoner insomniaque (1883, Richepin), formed on the model of cardiaque and maniaque.[4]
