Labyrinth
Definition:
(n.) An edifice or place full of intricate passageways which render it difficult to find the way from the interior to the entrance; as, the Egyptian and Cretan labyrinths.
(n.) Any intricate or involved inclosure; especially, an ornamental maze or inclosure in a park or garden.
(n.) Any object or arrangement of an intricate or involved form, or having a very complicated nature.
(n.) An inextricable or bewildering difficulty.
(n.) The internal ear. See Note under Ear.
