Today, millions of be-ghouled kids across North America will be facing the disappointment of “fun size” candy as they trick-or-treat for Halloween. While “fun size” may sour any ghost or goblin, candy makes for a quite the sweet and surprising etymology.

Candy
Following in the tradition of the Romance languages, the earliest appearance of candy is in sugar-candy in 1390. From the French (sucre candi) and, previously, Latin (saccharum candi), we can unwrap the Arabic qand, “the crystallized juice of the sugar-cane” (Oxford English Dictionary [OED]). Passing through to Arabic from Persian, the word is connected to the Sanskrit khanda (“piece,” as in “piece of candy”), from the verb khand “to break.” (I think of small chunks of brittle as a visual reference, for whatever it’s worth.) The Online Etymology Dictionary proposes a Tamil root for “to harden.” Tamil, you may recall in my second post on “citrus,” is a Dravidian language, found in southern India and Sri Lanka.
Now that’s quite the Halloween haul.
Both sugar and cane also go back to the cradle of civilization, if you will, teaching us how ancient the “sweet-tooth” really is, to riff on Jordan Shipley’s commentary on these words. With both passing into English via the sturdy stock of French, Latin, and Greek, the former we can trace back to the Arabic sukkar (“sugar”), which has been connected to a Sanskrit word for “grit,” as in “ground-up,” like, well, grains of sugar. The historical phonology of sugar is quite ghoulish, however.
The latter, cane, is via a Semitic root, qanah, “reed,” which itself some link to the Sumerian gin, meaning the same. This root may also be part of the origin of caramel, along with the Indo-European root for “honey.” Canyon, canal, canister, cannon, and canon all, to various degrees, may be related to cane.
I know this holiday isn’t even over, but I have to put out one yuletide decoration briefly: A candy cane may evoke Christmas, which, culturally speaking, is about as Christian and Western as it gets, but etymologically, we can see that candy cane comes from a whole different world. Now that’s quite the treat, isn’t?
Speaking of Arabic, ghoul is another Halloween-y word that ultimately haunts the Arabic-speaking world. First appearing in English in a 1786 translation of a French-language Gothic novel called Vathek, the word goes back to the Arabic ghul, referring to an “evil spirit” believed in Muslim countries to “rob graves and prey on corpses” (OED). The word is further rooted in a verb meaning “to seize.”
Seize away, ghoul, as long as you don’t steal my candy.
