wonderworld
A place full of delights or marvels.
What indeed, is every—the commonest phenomenon but a wonder and a mystery;—every flower a riddle; every blade of grass an open secret; every mite that glistens in the sunbeam a point from which the universe opens outward? This world is no less a mystery and a wonder-world than the world beyond, and were it not for our close familiarity with it, by which our sense is blunted we should at once perceive it to be no less so.
Where it comes from
From wonder + world; compare the coincidentally equivalently formed Old English wundorworuld (“wonderful world”).
