If walking into a bookstore makes you feel like your eyes are bigger than your bookshelves back home, you’ve got a bookworm-unique condition called Tsundoku.
Tsundoku is the stockpiling of books never consumed. Sahoko Ichikawa, a senior lecturer in Japanese at Cornell University, explains that tsunde means “to stack things” and oku is “to leave for a while.” The word originated in Japan’s late 19th-century Meiji Era from a play on words. Sometime around the turn of the century, the oku in tsunde oku was replaced with doku, meaning to read. But because tsunde doku rolls awkwardly off the tongue, the mashup version became tsundoku.
