  • IPA (Ecclesiastical): [ˈnɛː.bu.la], [ˈnɛː.bu.la][1]

Forms

nebula f (genitive nebulae); first declension[1]

Etymology

It is inherited from Proto-Italic *nefelā-, inherited from Proto-Indo-European *nebʰ-e-lo- (“small cloud”), from the root *nebʰ-, which the TLL glosses “to be moist, cloudy”.[2][3][1]

Cognate with Middle Welsh nyfel (“clouds”), Ancient Greek νεφέλη (nephélē, “cloud”), Old Norse nifl (“darkness, haze”) and Old High German nebul (“mist, fog”),[2][4] and with Sanskrit नभस् (nábhas, “mist, sky”).[3][1]

Earliest recorded meaning

It is found from Plautus onwards.[2][5] In the Amphitruo Plautus says that mist is made of breath and panting.[4]

Semantic evolution

It meant mist or fog and, in poetry, a cloud, and Lucretius used it for clouds of dust and smoke.[4][6] Ovid and Martial used it for a thin film, and Pliny the Elder for a sea creature that pearl divers dread.[4] Figuratively it meant obscurity or a cloud of confusion, as in Gellius.[4][6] Terence already has its derivative nebulo “good-for-nothing”.[2]

In Medieval Latin it was also a wafer, including the host of the Mass.[7][5][8] It survives as Romanian negură, Italian nebbia, Spanish niebla and Portuguese névoa.[1] English took nebula for a cloud in the 15th century and, about 1730, for a cloudlike patch in the night sky.[9]
