Etymology

Origin of labyrinthine

First recorded in 1740–50; labyrinth + -ine 1

Explanation

Labyrinthine is a good word to describe a place that feels like an enormous maze. A new student at a huge, sprawling high school is likely to find the building labyrinthine as she wanders the halls looking for her math class. If you've ever been lost in a hedge maze, you know what a labyrinth is. The adjective labyrinthine describes something that is as confusing, complex, or maze-like as a labyrinth. This could be an actual maze, a city, or even a convoluted idea. The word comes from the Greek labyrinthos, the structure built to contain the mythological Minotaur. In the story, Daedalus did such a good job making the building labyrinthine that he nearly couldn't find his way out.
