I’m halfway through Annihilation (thanks, bulbul!), and one of the pleasures of the book is discovering phrases hitherto unknown to me that are attractive as linguistic items and interesting as real-world phenomena; so far they’re all biological, because the narrator of the book is a biologist:
Interestingly, a velvet ant is not an ant, a sea oat is not an oat, and a cypress knee is not a knee. Natural language is not transparent!
