A few weeks ago, my husband and I were discussing words used for rooms or spaces that made no sense to us, and I brought up arcade. The only time I’ve really encountered this word “live,” so to speak, is in a video game arcade. So when I was researching Paris for The Collector of Burned Books and realized that an area of posh flats above the Champs-Elysee are also called “The Arcades,” I knew there had to be a meaning of this word that I didn’t know.

The word arcade has the hint of its root meaning right there in the word: arc, or arch. It’s from the Latin arcus, which then was used in the Italian arcata for an “arch of a bridge.” The French borrowed the word from there, using it to describe a vaulted space (hence those high-end apartments).

English adopted the word in 1731 with that same meaning and took to applying it to the spaces or passages formed by a succession of arches–think avenues of trees or a space beneath piers or pillars. By the late 1700s, it was used to refer to the spaces under a covered avenue that was lined with shops…and amusements. That’s ultimately where arcade games comes from, though that particular phrase dates only to 1977.
