nebula
Pronunciation
- IPA: /ˈnɛb.jə.lə/[1]
Etymology
It is borrowed from Latin nebula (“mist, vapour, cloud”),[2][3][4][5] first as inherited from Middle English nebule,[2][3][4] from Proto-Indo-European *nebh- (“cloud”).[4][2][6] It is related to Ancient Greek νεφέλη (nephélē, “cloud”), νέφος (néphos), Sanskrit नभस् (nábhas, “mist, sky”), Old High German nebul (“fog”) (German Nebel) and Old English nifol (“dark”).[3][7][6][8]
Earliest recorded meaning
As nebule, a cloud or mist (before 1449 in Barnhart; mid-15th century in Etymonline).[3][4]
Semantic evolution
In Middle English the word had several medical uses.[9] It was reborrowed from Latin in 1661 for a film or cloudy spot on the eye,[10][3][4] and later for cloudiness in the urine.[2][11] The astronomical sense, a cloudlike patch in the heavens, is first recorded in 1718, used by Edmond Halley,[9][8] or 1727–38 in the OED and Barnhart.[10][3] As early as 1802 Herschel realized that some nebulae were star clusters,[4] and the word was long used of galaxies beyond the Milky Way before astronomers distinguished nearby clouds of gas from distant galaxies.[4][5][11] Kant first proposed the nebular hypothesis of the origin of the solar system.[12]
