In researching this wonderful subject of mine, I’ve often seen the word Celiac spelled Coeliac (pronounced the same.)
Turns out it’s only North America that spells the word sans O. Europe and Australia use Coeliac because it derives from the œ symbol used overseas.
While we’re on the subject of Celiac etymology, I found this Wikipedia excerpt interesting:
“This condition has several other names, including: cœliac disease (with œ ligature), c(o)eliac sprue, non-tropical sprue, endemic sprue, gluten enteropathy or gluten-sensitive enteropathy, and gluten intolerance. The term coeliac derives from the Greek κοιλιακός (koiliakόs, “abdominal”), and was introduced in the 19th century in a translation of what is generally regarded as an ancient Greek description of the disease by Aretaeus of Cappadocia.”
