I thought we did have a word of the day thread around somewhere, i'll have a geezer. If not i'll leave as is.
EDIT - I must have been wrong i guess. Couldn't find what I thought I was looking for.
i'll get back to you with a word.
I'm not pulling this from anywhere online but I heard a friend use this word before just the other day.
So I'm going with ANFRACTUOSITY
A channel, crevice or passage full of windings and turnings.
Not quite describing a maze, though some mazes certainly take on an anfractuous appearance, one that is sinuous or winding. The noun is rare enough that it is hard to find examples, the adjective almost equally so.
One sense is of a broken or jumbled landscape. T S Eliot used this in his poem Sweeny Erect: “Paint me the bold anfractuous rocks / Faced by the snarled and yelping seas”.
The word comes from Latin anfractus, a bending around, from the verb frangere, to break. So it is a close cousin of the much more recent fractal, as well as fracture, fragile, refraction, and, rather less obviously, infringe and osprey (the latter ultimately derives from ossifraga, bone breaker, originally applied to the lammergeier).
