Definition of "moony"

(Her white throat whiter than a moony pearl / Just threaded with a blue vein’s tapestry / Had not yet ceased to throb, and still her breast / Swayed like a wind-stirred lily in ambiguous unrest)

1881, Oscar Wilde, “Charmides”, in Poems‎

And oft at midnight’s moony sceneA faded form of ghastly mien Across the waves doth glide;And oft upon the passing galesA plaintive voice the ear assails, When wand’ring by the tide.

1816, Dorothea Primrose Campbell, “Agnes And the Water-Sprite”, in Poems‎, London: Baldwin, Cradock, and Joy, page 26

It was an extraordinary sight. Even the light was extraordinary, a kind of reddy-coloured twilight, on account of the streamers of seaweed that floated up on either side of the ship. And far overhead just a moony, deep green-blue.

I peered at his rather featureless face through the moony twilight; and then he suddenly rose and paced the path with the impatience of a schoolboy.

Less violent, but no less eerie, was a teenage girl with Down’s syndrome who suddenly lolloped up to me on a sidewalk in Tacoma, Washington – I being then a morose and moony college student – and kissed me on the cheek.

In one of his earliest known paintings, A Carnival Evening, which was shown at the Salon des Independants in 1886, the clown may reflect the influence of Watteau, the clown's girlfriend perhaps was taken from an advertisement for chocolates, the lacy tangle of branches in the trees possibly echoes a postcard photograph of the Bois de Boulogne. They all fit together in a moony atmosphere which is the Duanier's own.
