Learned borrowing from Latin nimbus (“dark cloud”). Doublet of nimb.
Sense 2 (“grey rain cloud”) was coined by the British chemist and amateur meteorologist Luke Howard (1772–1864): see the 1803 quotation.
nimbus (plural nimbi or nimbuses)
Seemingly from Proto-Indo-European *nébʰos (“cloud”) with an *-n- infix, but the formal details are disputed. Possibly contaminated either by a zero-grade variant *imbus or by the related word imber (“rain”), if not borrowed from another Indo-European language. Cognates include Latin nebula, Proto-Slavic *nebo (“heaven, sky”), Sanskrit नभस् (nábhas, “sky”) and Ancient Greek νέφος (néphos, “cloud”).
