Other forms: bibliophages
If you ever snuck a book and a flashlight into bed to read under the covers past bedtime, or got scolded for reading a book when you should have been doing your chores, you might be a bibliophage: an avid reader.
The word bibliophage is composed of two Greek elements: biblio, meaning "book," and the suffix -phage, "one that eats." A bibliophage is quite literally a book-eater, but the word is more frequently used metaphorically. Someone who reads books voraciously, as though they're hungry for them or need them to survive, could be described as a bibliophage, or more commonly, as a "bookworm."
