How from that sapphire fount the crispèd brooks,
Rolling on orient pearl and sands of gold,
With mazy error under pendant shades
Ran nectar, visiting each plant, and fed
Flowers worthy of Paradise …—John Milton, Paradise Lost (iv. 237–241).
So muses Satan on the nectar flowing through Eden. But how much thought does he give to the adjectives derived therefrom: is that flow nectarean or nectareal, or is it paradisean, or perhaps paradisiacal?
In 1968, Fowler’s opines:
nectar has kept the word-makers busy in search of its adjective; nectareal, nectarean, nectared, nectareous, nectarian, nectariferous, nectarine, nectareous, and nectarous, have all been given a chance. Milton, with nectared, nectarine, and nectarous, keeps clear of the four-syllabled forms in which the accent is drawn away from the significant part; and we might do worse than let him decide for us.
So which one won out?
