incubate: incubate: [18] Latin incubāre, the source of English incubate, meant literally ‘lie down on’. It was based on the verb cubāre ‘lie’, which also produced English concubine and cubicle. The notion of ‘lying on eggs to hatch them’ seems later to have fed back into the simple verb cubāre, which in this sense gave English couvade ‘male mimicking of child-bearing’ [19] (an anthropological term borrowed from French) and covey [14].

Another English descendant of incubāre is incubus ‘male demon that has sex with a sleeping woman’ [14], literally ‘one who lies down on another’ (its counterpart is the succubus ‘female demon that has sex with a sleeping man’ [16], literally ‘one who lies down under another’). The nasalized version of the stem of Latin cubāre gave English incumbent [16] (which etymologically means ‘resting upon as a duty’) and recumbent [17].
