Pronunciation

Forms

incube m (plural incubes)[1] Middle French also incubon, and the Latin form incubus used in French texts.[2][3]

Etymology

It is borrowed from Late Latin incubus (“nightmare, satyr”), a Late Latin derivative of classical incubō (“to lie on”).[3][4][5] Littré analyses the Latin verb as in- and cubō (“to lie down”).[6] Bloch and Wartburg explain that the Latin word for a nightmare, the weight felt on the sleeper, came to name in Church Latin the demon believed to lie on sleeping women.[7] The learned form incubus “nightmare” is already used in French by Aldobrandino of Siena about 1256.[3][8][9] The Anglo-Norman Dictionary has Anglo-Norman incube “demon, evil spirit”, with the spellings inchube and incubus, from 1155.[10]

Wiktionary treats the modern word as inherited from the Old French word, itself borrowed from Latin.[1]

Earliest recorded meaning

In Aldobrandino of Siena's Régime du corps (about 1256) incubus is the nightmare, the feeling of a weight pressing on the sleeper, which the text glosses in French as apesart.[11][3] The form incube for the demon is dated 1372 by the TLFi, in Jean Corbichon's translation of the Propriétés des choses, where it is named beside satyrs.[3][7]

Semantic evolution

In the 14th century the word is used both as an adjective, of a demon “that couples with a sleeping person” (un deable incube, Bersuire, about 1354–1359), and as a noun beside its female counterpart subcube.[12] The older medical sense “nightmare” stayed alive in Latin form: Ambroise Paré in the 16th century explains incubus as a night illness in which one feels crushed by a heavy load, and describes the incubes as demons taking the shape of men to lie with witches.[6]

Richelet in 1680 records the word in the sense “lesbian”, which did not last.[4] In modern French incube is a term of theology and demonology, the male demon set against the succube;[3][13] Huysmans used the rare derivative incubat “the nature of the incubus” in 1891.[4][3]
