Geophagy

Postby Palewriter » Wed Aug 16, 2006 11:04 pm

Geophagy (n)

The practice of eating earth, such as clay, chalk or dirt. Apparently a condition dependent on a dietary deficiency, causing the subject to seek a supplement in earth. In simple terms: eating dirt.

The compulsive habit of chewing on clay (chalk, etc) is called geophagia. Other related nouns are: geophagism and geophagist.

In use:

I like to use this rather arcane word in the sense: "I'd rather practice geophagy than visit Mother-in-Law this weekend."

According to the Online Etymoligical Dictionary:

"A diseased appetite ... prevails in several parts of Alabama, where they eat clay. I heard various speculations on the origin of this singular propensity, called 'geophagy' in some medical books." [Lyell, 1850]

Who knew?

Origin:

Greek: geo- "earth" + phagein "to eat." (Etymonline points out that "the actual Gk. was geotragia"

My sister's pony (well, technically, it's her daughter's pony) evidently has this habit. It sure was delighted to be scarfing down some of their sandy terrain while we were visiting her over the summer.

I thought immediately that the pony's diet must be short of some mineral... but the soil there (they live in the Sandhills region of NC) doesn't seem like it would be very rich in any particular minerals, other than silicon!

I liked Designing Women. But I've always had a thing for strong-willed women. ;)
